Nikon SB-900 Foot: Size 16 EEEE

The new Nikon SB-900 Speedlights are dropping into stock pretty much everywhere, albeit on allocation.

But before you buy, you might want to check this thread for a running update on what the flash shoes the newly designed foot will -- and won't -- fit. Please feel free to add to this list if you find out anything first hand.

And remember that they do ship with an AS-21 foot, which can be swapped out if your system is 1/4 x 20-based. But mind that plastic thread if you are swapping out frequently.

Speedlights, South Africa Style

South African photographer (and Strobist reader) Robert Miller, whom you may also know as "Panascape" on Flickr, has been showing up in PIX African Photo Journal so often he should be paying them rent.

Back in the March edition, Miller wrote and photographed a story entitled, "Welcome to Strobist." He got four pages for his story and another four pages about his photography in the form of a monolith/Q&A piece. Not a bad month.

Then he pops up in my mailbox today with a stitched, HDR panorama with embedded lit portrait on the current, triple fold-out cover -- which is basically a PIX magazine geargasm to the new Nikon D700. (It wraps around to the back cover, too. Craziness.)

We'd never do the ad / cover / fold-out ad thing like that in the States. But seeing that kind of stuff is one of the reasons I love reading foreign photo mags. Even as an old Chinese Wall newspaper guy, I have to admit it is pretty friggin' cool for PIX to announce a long-awaited camera like that.

Links and a diagram, after the jump.

Here's the setup for the top photo. Two umbrellas and a ring light. Click the diagram to read more info in Robert's comment stream, where he talks about how he built the flash and ambient ratio for the shot.

As far as my photo, which pretty much looks like a little turd compared to Robert's stuff, I stuck an SB-800 at camera left and exposed for the flash at about 1 stop above the ambient. Location: My mail box.

Hands-On Review: Nikon SB-900 Speedlight

I got a chance to play with a new Nikon SB-900 speedlight over the last few days and I gotta say, it's a pretty sweet flash. Long story short: Nikon has just extended their lead in the flash department.

The only drawback I can see is the "perfectly good" status of the current SB-800. And that $500 price tag, of course.

Should you get one? Swap out all of your SB-800s? Be on the lookout for cheap, used SB-800s and add more?

Hit the jump for the Full Monty review, and a few things you might want to consider.
_________

First impression: It is much bigger than the SB-800. Didn't really seem any heavier, but definitely takes up more space. This is a consideration for a couple of reasons. One, cubic inches matter when on the road. Not so much on a single flash basis, but if you are packing half a dozen SB-900s, you could probably cram seven SB-800's in the same space.

Also, the head is a totally new design and size. This means that your current light modifiers may or may not fit the SB-900, depending on their size and/or mounting flexibility.


So here's that big ol' honker of a head. First glance, it looks to be pretty much the biggest speedlight head going, save maybe the Vivitar 285 HV. It looks bigger than an old SB-26, and certainly bigger than an SB-24.

If you can get past the size, they have done some really cool things with the extra space. The 200mm zoom rocks. Not because I am gonna direct flash with my 70-200 racked out. But because it will concentrate the beam, of light into a smaller area when used off-camera.

Why would you care? Because it effectively gives you a more powerful flash when large swaths of light are not needed. Like doing a hard-light, multi-flash portrait outdoors, for example. You usually would not want to light their feet anyway.

Rather than eat up that needless beam angle with a snoot or grid, you can zoom it in, and get some extra f-stop with the more concentrated beam. This translates into more control over the ambient light level (you can get a darker working f-stop at 1/250th, for example) for more choices in your ambient tones.

Of course, you can get a Better Beamer to stick on just about any flash to do this, but it is not built-in.

The Big Head Advantages do not stop there. It's the most sophisticated refractor/reflector system I have ever seen on a flash. They actually modulate the tube with respect to both the front fresnel and the polished, rear reflector. This gives you the ability to shape the internal qualities of the beam, too.

You can choose a normal (slightly concentrated) pattern, an even more concentrated pattern (again, yet more energy to the center for situations described above) or a near-perfectly even light distribution depending on your lighting needs.

That's a real breakthrough in speedlight design, and brings to a (relatively) small package more of the capabilities of an interchangeable-reflector studio strobe. Big props to Nikon for that.


Other advantages that argue for switching are the new CLS interface. You'll get back the time you spend wading through the CLS menus on your master flash. This would not be a reason to swap out, say, four flashes. But it might be good reason to get one to use as a master.

It's basically a manual switch and a wheel dial -- a very fast an intuitive combo for switching setting in very little time. It took a little digging to find the SU-4 mode, which we like because it activates an awesome built-in slave, but I can confirm it is included and does work it's manual-power slaved-flash magic.

I actually used that mode to sync all of the flashes used to make the shots in this post. More on that later.


Big on the advantage list: Recycle time absolutely rocks at 2 seconds with no accessory battery back. Better circuitry uses the same power source -- with much faster recycling. This is a dream with Ni-MH batts, and the fifth-wheel option is no longer needed for fast shooting. For some, this will warrant swapping out their main, on-camera flash.

The accessory SD-9 battery pack walks that already fast recycle time down to about a second at full power. And it can hobble along on just four extra batts if needed, according to the Nikon guys I spoke with.

Interesting point: The power plug on the SD-9 has two extra nubs which means it will not fit other flashes. But the design looks as if the current SD-8-type plug may fit the SB-900. This is important if you are going to be migrating other existing battery packs to the SB-900.


Thankfully, the PC jack is still there. Big ups to Nikon for including the old-school synching, in addition to the fancy-pants CLS stuff.

One other noteworthy change is that the SB-900 swings both ways -- you can go reverse 180 in either direction. This is especially useful, in that whichever way you mount a remote flash you can have the receiving window facing the master light source.

Before, there were situations in which you had to cheat that angle and lose wireless range as a result. Every flash should have this feature, IMO.


In Sync:

1. It comes with a gel holder, which totally rocks. No more tape and/or velcro. And the dome diffuser fits right over the gel holder, allowing both to be used at once. The bar-coded Nikon gel thing is a little gimmicky -- it sets your camera's WB to the "appropriate" setting. The special Nikon gels could easily be duped with a template and some liquid paper. You will not need to re-up with the official Nikon gels ($$) if you do not want to.

2. Goofy, but cool: At full power, the discharge sounds like a blaster from Star Wars ("pew, pew, pew"). Recycling is almost silent. And oh-so-fast.

3. My seven year-old boy loved the battery compartment: Individual cylindrical battery holes -- like loading a revolver.

4. Thermal shut-down protection -- which can be disabled if you are completely stupid. Cool detail: A "thermometer" in the rear display shows you if you are starting to red-line it.


Out of Sync:

1. Five. Hundred. Dollars.

2. The hot shoe is a new, thicker size that will not fit many current accessory shoes. McNally dropped one out of a Justin Clamp, which is a staple lighting tool. (The Nikon guys mentioned that about 5 times this weekend, Joe. They might be sending the black helicopters after you shortly...)

3. The new AS-21 foot must be used because of the new shoe size. Which would be fine, except for that the metal female 1/4 x 20 insert in the AS-19 has been replaced by mere molded plastic in the AS-21. This will be a problem for people who repeatedly use the AS-21 on an umbrella swivel. That's a design whiff that should not have happened. (More on that here.)



Decision Time

So, that to do?

My biggest problem is, I absolutely love the SB-800s. IMO, many of the added features are great. But I do not think I can justify switching everything out wholesale. Buying just one might be a very good idea -- I can see many instances when those extra features would make for a more useful single flash.

My other problem: They may well choose to discontinue the SB-800, which would be a crying shame. It's either that or create a whole new production line for the SB-900. The SB-800 is small, powerful and does everything. Many will continue to prefer it to the SB-900, given price difference and the fact that the core functionality is the same. Seriously, what's so wrong with this current flash?

But of course, that's how my grandmother felt about her rotary-dial ATT phone, too. I am officially old now.

I know one thing -- if they do drop the SB-800, the '900 is gonna sell a crapload of SB-600 flashes. Thats a huge price gap which many amateurs will not be able to rationalize. And the smart move for new CLS'ers might be one '900 and a few '600's. Who knows.

The SB-900s are already pre-selling like crazy. So Nikon is clearly doing something right. My hope: SB-800s go out of vogue with the doctors, dentists, and rich soccer moms and they all wind up in the used dept and on Ebay for $200 a pop.

'Cause if that happened, I'd pimp out my lighting bag like McNally's. (Only, he'd have 72 SB-900s by then...)


Lighting These Photos

For the top photo (shown again here) I set the subject flashes on SU-4 slave mode in manual, at 1/128th power. Since they were only a few inches away from each other this would be my limiting factor, even dialed down to 1/128th. A quick pop-and-chimp, and I was adjusted to the aperture that gave me a good exposure from each other's close-in light.

I shot these with a new Nikon D700, BTW. We were absolutely swimming in new toys this weekend at Shoot! The Day in NYC. Awesome little camera, that '700. D3 guts in a D300 body. Expect iPhone 3G-esque wait times for a while if you want one.

Anyway, once I got the best shooting aperture for the flash-to-flash light from the subject flashes, I manually adjusted the other lights to look good at the chosen aperture, which I believe was f/16. I shot at a 250th, to nuke the ambient away. I put the flashes on a shiny black table and shot low, to maximize the reflection.


Other lights were:


• An SB-800 aimed at the background from under the table, using the frosted diffuser for an even gradient.

• Two SB-800's as rim lights, which edge-lights all of the shiny black surfaces.

• An on-camera flash in a Ray Flash adapter, which gave me the specular highlights on the front surfaces.


You Tell Me

Nikon shooters: Are you gonna get one? Are you gonna swap out your SB-800s? Why? Why not?

I'm on the fence, and looking for feedback...

One-Light Night Landscape

New in the Strobist Reader Gallery is Jonathan Boeke's night shot of a stand of trees.

It's done with multiple pops, during a time exposure. And it is easier than you might think. Keep reading for a few tips on creating shot like this, next time you are alone in the woods at night...

For this shot, Jonathan walked to a spot behind each tree and fired a Nikon SB-600 with a green gel back at the camera while the shutter was open during a time exposure. (You can click on the pic for the comment thread, and his explanation.)

If you have a camera that supports multiple exposure, you can eliminate a lot of noise (and logistical problems) from the frame by shooting the frame as a sequence of higher-shutter speed multi-exposure shots.

But you'd need a shutter cord and a third remote (or a helper and a tripod) to do that. You can see how to do the channel-hopping relay mode here.

If you wanna go multi exposure, you can do it with no remotes at all. Just open that shutter and start running. I've pulled together a few ideas to help your photo, and save some work in post production.
___________


• Wear dark clothing. Nice to have a dark hoodie, too, just in case you do not have one of those face-hiding ninja masks lying around.


• Snoot the flash just a teensy bit. You still want a nice, wide beam, so just do a half-inch or so. Black gaffer's tape works great. But that little ridge will help avoid blowback in the exposure, which can light you up if you have limbs visible to the camera.


• Mount a very dim light source close to the vertical axis of the lens at the camera. Maybe an LED flashlight, aimed up, mounted to the hot shoe. This will let you know when the tree is hiding you (and your flash) from the camera very precisely as you walk around in the background.


• Consider varying your distance from behind the trees as you pop each flash shot. You can throw light a long distance, and light up big chunks of your background that way. Be sure to crank up the power some (adjust with a few test shots) to account for the increased flash-to-blocking-tree distance. And multiple pops could be your friend here, too.


• If you aim the flash up a little (or a lot) you'll light the leaves in the trees better. Especially in the background, where more height from the trees will be visible to catch the light. This will also avoid the hot spot being visible at your feet.


• Remember that the light behind the far trees acts as a nice rim for the nearer trees, so take that light-to-subject distance into account when planning how far back to get behind the rear light pops. (Remember L102 Position -- evenness increases with distance.)


• Watch your ambient lights, to keep from tracking. Gaffer tape everything that would give off light while you are busy walking around in your frame. Your flash ready light and info panel backlight need to go dark. Ditto anything else that might be glowing or blinking, like a Pocket Wizard status LED.
___________


If you are gonna try this on your own, tag your shot "strobist" and "backlitforest" (the latter is all one word) so we can see all of them at once by clicking here. I am thinking of trying one myself, and it might be fun to revisit in a future post.

Speedlinks, July 18, 2008

I'm up in NYC, gearing up for tomorrow's lighting seminar and Sunday's "Shoot! The Day" classes. But there's still time for a fresh batch of speedlinks!


• Thomas Graves has an excellent real-world review of the RadioPoppers at Light-Shoot-Print.

• Remember Joey Lawrence? He's been in Moldova, shooting cats the King of the Gypsies and has a video which includes the lighting setup. That kid is something. Eighteen frickin' years old and never home.

(Warning: The audio is NSFW, and the video is NSF cat lovers...)

• My friend Kevin Coloton is doing foot race finishes with a quad-speedlight setup, shooting motor sequences on 1/16th power. Knowing some of you are into this, I wanted to point you to his team's blog post -- complete with pix, a diagram and video.

• Chris Claborne has posted a review of the brand new AlienBees CyberSyncs in the Strobist Flickr threads.

• Back in the late 70's and early 80's I spent a lot of times in some, uh, pretty creative darkrooms. And I saw more than one photographer printing on grass. But never like this...

Rembrandt Lighting? Um, No.

Phoenix-based shooter Blair Bunting must have been asleep the day they taught the classic portrait lighting styles in school. Either that, or he skipped right past "Rembrandt" and went straight to "Badass."

Bunting is part of a movement of a high-def lighting style that is especially well-suited to subjects like athletes, rock musicians, MMA fighters, assassins, orcs, etc.

Keep reading for full lighting diagrams (hint: lots of sources) and some Q&A on Bunting's techniques and lighting philosophy.
________


The first thing to consider when sculpting light like this is to leave some shadow. The light's edge is defined by shadow, which is what creates the form. The other thing to remember is that the intensity of the surface of the subject also is revealed by specular highlights. And each light source is going to create a specular of some kind.

Placing lights where you want them -- and keeping them away from where you do not -- is the balance you need to strike to make this kind of photo.

To get an idea of what it took to create this look for a portrait of Arizona State running back Keegan Herring, check out the top-view and front-view lighting diagrams, below.


Top View



Looking at this angle, you can see that Herring is lit from just about everywhere except the lens axis. This is what makes the lights define him in such a cool way. Again, you have to leave shadow to get form.

But each of those lights his the subject on a glancing blow, with respect to the lens axis, and that is what creates the cool highlights.

Lotta lights? Yeah. It's pretty much walking into a camera store and asking for two of everything they have. But it is a look. And it's a look that will make a college sports information department do the Happy Dance and call you back year after year. Just like they do for Bunting.


Front View


To look at the top view, you'd think Herring is inside of a cylinder of light, but that does not take into account the varying heights of the light sources, which in this way creates yet more sculpting with shadows.

From this angle, you should really start to see the light coming together.

Height-wise, the strips and small square boxes are doing the heavy lifting, lighting the body and face. But it is the beauty dish (don't call it that in front of Herring) grids and reflector that create the edge everywhere.

"Yeah, yeah," you say. "It's really all done in post. Ten minutes of shooting and two days of Photoshop."


Yeah, well, maybe not so much as you think. In fact, Blair was kind enough to release a raw photo, seen at left, which shows you just how close he gets with light.

From there, it's pretty quick and basic in Photoshop. It always helps to start with the best file possible. And the closer you can get in the camera, they better. That said, Bunting notes that he tends to think of light as expression, rather than as a process. He said he uses light to create opinion and emotion.

He gets the "what light is best?" question a lot, to which he responds:

"Buy what you can afford. The reasoning behind my answer is that I am of firm belief that practice is more significant than any brand name. I have been fortunate enough to use numerous different brands of lights, hot and cold, small and large."

As for tools vs. vision, he says, "I fall into a rhythm where my tools give way to my vision and my eye produces what my mind wants to see. Be it Profotos, Alien Bees, or SB-800's, one can create with all of these."

He particularly worries for the beginning photographer who finds his or her approach inferior to a photographer using more expensive lights. He feels that mindset is a dangerous mental handicap, and wishes it on no one.

Where does he get his inspiration? You might be surprised:

"Often times I find that the music I listen to can determine my lighting approach more than anything else. With my eyes closed, a glass of wine, and a powerful score (or any song that drives you within for that matter) I sit and think of light not as this invisible substance, but a tangible entity."

He goes on:

"Mentally I observe it like wind and smoke and try to imagine how it should form my subject. This is particularly practical when shooting cars as many people hit a road block with the reflectivity of metal."

Bunting also thinks of light as water, using analogies of hard vs. soft, narrow vs. wide beams and hot vs. cold. It's an organic way of describing light that I had never considered, but it has me thinking.

He advises photographers to consider, and learn, the power of a single light source. Know what a single, silver umbrella can do for your subject, and to respect light.

Lest this all get too philosophical, I hit him up with some specific questions:



Q and A

1. The lighting design for the football player is killer. How did you evolve this particular lighting style? Were you influenced by video games? Movies? Other shooters?

Oddly enough, this one was music and visualizing for endless hours. I lived with my Ipod in and would skip lunches to plan (this shoot had 10 shots to be done in 2 hours). For this one in particular I listened to everything from the Gladiator theme (“The Battle” by Hans Zimmer) to death metal.

The idea was to make the scariest person imaginable. So the lighting was based off of discomfort, a lot of lights, a lot of speculars, a lot of chaos. The idea of the lighting came from the countless movies where you can barely see the person, rather an outline; in this case I wanted it carried a bit further with his eyes.


2. Do you find you get hired to do a certain look? Do you feel you still have creative freedom?

I have been especially fortunate in this area. It is often that I get booked by clients that have someone of a concept and want my style to carry it, which in turn lends a great deal of creative freedom my way. Other times I will be booked by a client that maybe wants a less moody image, but still wants my view brought into the shot, either way the freedom is there.

The downside is sometimes all I want to do is think about lighting and would give anything for a set in stone storyboard where I came in, followed directions, lit, shot and went home.


3. That's, um, a lot of light sources. Typically a shooter would not start out with an arsenal like that. What kind of approach were you using when you had fewer lights?

I am a huge fan of shooting one source, and often have usually with one silver umbrella. Another way I saw lighting (when using fewer sources) was making sure that the eye saw a comfortable single direction in the photo, and from there countering that source with a fill to keep the contrast ratio down.


4. Given that many watt-second deployed against a single player, how do you adapt that look to larger subjects -- say, an offensive line?

This is sometimes a task, in all honesty. The football player need a lot of light since the shot was done with a digital medium format system, which requires more than a 35mm.

I will usually try and bring larger packs (preference going to the Profoto D4 4800). However, there are just times when there are not enough lights and the budget isn’t open enough to bring in 20 or 30 heads. (DH note: 20 or 30?!?) In this case I improvise and try to visualize the scene with a single light source and take small steps building off that to a minimalist approach.

5. Is heavy post production an important part of this look? If so, how close do you get with the light and how much needs to be done in post?

In all reality I am not that savvy with Photoshop. Because of this lighting has to be perfect. I have seen guys take snapshots of cars and make them look like a studio shot. I respect this approach, but it’s just not mine and is dangerous if an AD is on set and wants to visualize a shot for placement. Much of the work I do looks extremely close to what is seen in the LCD on set with added contrast, polishing and sharpening. I have included the jpeg for the football player shot for reference as a file that has not seen Photoshop.

Blair posted a brief video vignette from other parts of this same shoot to YouTube:

Orbis Ring Flash Adapter Details


An email from Enlight Photo dropped into my box tonight with some fresh detail on the upcoming Orbis Ring Flash Adapter. It's similar in function (if not design) to the Ray Flash adapter, with some key differences:

• The flash is mounted off-camera, similar to many of the DIY designs we have seen.

• From the light source reflections in some of the test shots on the updated website, it appears to be a little softer (bigger) light source than the Ray Flash.

• Price is said to be "under $200".

• No word on efficiency, relative to direct flash. (Ray Flash is minus just one stop compared to direct flash.)


More info, email list sign up, pre-sale info, etc. -- here.
