Senior high school photo shoot: Justin

Lee Ann's grandson Justin is graduating next spring, and he and his mother asked me to shoot his outdoor senior high school shots recently. They pushed the timing of the shoot almost as late into the year as my niece Erin's family did two years ago, but fortunately, we found a day and time on Nov. 3 to squeeze in a late-afternoon session in Garfield Park in Indianapolis.

Unfortunately, Justin, who lives in Fishers, couldn't get to the park until after school that day, a Tuesday, so we started later than I would have liked. Darkness sets in much earlier these days since clocks rolled back for standard time earlier this month, so we tried to work quickly.

We got pictures of Justin and his girlfriend, Rae, in a dozen or so poses while we had good daylight. A few were taken inside the pagoda, others outside the amphitheater to exploit the brick facade, a few along the jagged stone staircase south of the arts center and several leaning against a tree and a light pole. (I did not attempt to get permission from Rae or her parents to use any of the photos with her in them for this post, which is why you don't see any of her here).

When it became too dark to get decent background into the photos, Justin, an artsy guy, asked me to shoot some pictures of him in available light -- without flash. I didn't bring along my tripod, so I boosted the ISO to very high levels (2500 and beyond) so I could continue hand-holding the camera. I figured that if it was an artsy, "different" look he was interested in, he might not mind the noise from high ISO levels. We were near the amphitheater at the time, so all of those photos were near that facility. Justin seemed pleased with those shots, which for the most part were cast against dark backgrounds of minimal natural light and illuminated by the park's tungsten pole lamps. Such lighting brings harsh facial light contrasts that photographers ordinarily wouldn't seek, but Justin wanted that mood, that look.

As it turned out, I took several of those shots using shutter speeds too slow (e.g., 1/25) for hand-holding a camera without a lens equipped with built-in stabilization. Some of those shots had to be discarded, requiring a reshoot with higher ISOs and faster shutter speeds. A few of the picture with slow shutter speeds, however, amazingly, actually turned out OK. A special nod of thanks to Lee Anne, an experienced studio portrait photographer, who gets the credit for posing her grandson.

The photo leading off the post was taken inside the pagoda with camera settings of f/2, 1/180 and ISO 200. Right after that shot, we took another with the same camera settings -- this time with Justin smiling. That shot is the first below.

Photo geek stuff: For the entire shoot, I used my Canon 6D and Sigma 85mm f/1.4 lens, which I've turned to recently for all of my portraiture-related shoots to exploit that fast aperture and bokeh. For the majority of the shoot, I also used an on-camera flash, Canon 580EX II, in manual mode set at 80mm w/light intensities of 1/32 to 1/8, depending on the stage of natural light availability, to highlight the subject. The flash was equipped with a white Graslon Insight (flat) diffuser. I made a point to shoot most of the photos at or around f/2.0 or f/2.4, adjusting my ISO (which usually was in the vicinity of 160) to compensate for any needed light, which wasn't an issue until darkness set in. In the darkness, I boosted ISO levels to in the range of 2500 to 10,000. In post-processing, the subject's facial features were enhanced in Portrait Professional Studio software, version 11.

Better luck on 2nd try with Graslon

In my last post, I went into great detail to recall the experience I had with my inaugural use of recently purchased Graslon Prodigy on-camera light diffusers. Since then, I had a second chance to shoot the Garfield Shakespeare Company at another rehearsal for its spring production of Thornton Wilder's "The Matchmaker," and I again turned to the Graslon Prodigy -- the flat attachment (Graslon also makes a rounded, dome attachment for the Prodigy) -- for my lighting help.

This time, it was a good-news, good-news experience. Not only was I again pleased with the lighting the Prodigy gave me, but I made a point to be deliberate in the way I attached the diffuser to the flash head, a Canon 580EX II. This time, it attached firmly, and remained so for the duration of the shoot; it was snug, and at no time did I ever feel as if the device would not stay secure.

Curiously, after the second shoot, I received an email from a representative of Graslon, who had seen my previous blog post. It was a very impressive reach-out; the rep expressed disappointment that the modifier didn't attach properly for me, acknowledged that perhaps Graslon should have done a better job explaining how the mounting process should be handled, then explained that proper process to me.

As I told the Graslon rep in my email reply, I'm certain I had tried the "proper" mounting sequence -- albeit by dumb luck on my part -- in my inaugural outing. But I also admitted that in my frustration, it's very likely I slopped through it and moved on to -- and settled upon -- another method. Ironically, on the second shoot (again, before hearing from the Graslon rep), the process I used successfully was different from the one the rep described to me as the proper one.

In any event, I salute Graslon for reaching out, and I do feel better about that aspect of the device. Most importantly, I really do like the light it delivers. My camera settings for the second shoot of play rehearsal were the same as the first -- Canon 7D manual mode, 1/160, f/3.2, ISO-800; and the 580EX II in manual, 24mm zoom and 1/32 intensity.

I neglected to mention in my first post that in addition to the white-colored attachments, Graslon sells amber-tinted domes and flats for photographers to use when they want their light source to match tungsten ambient light.

The good and not-so-good about
Graslon flash unit light diffusers

When photographers have the time to set up lighting to take pictures using artificial light (i.e., flash and strobes), such as they do in portraits, it usually leads to pro-quality images. Photographers have great control of lighting in such situations.

But when artificial light is needed and the subject is not able to sit still (pretty much all other circumstances besides portraiture), photographers ordinarily have to attach their flash to the camera for convenience, but they usually struggle to find the right modifiers to deliver the illumination they want without introducing harsh shadows and that bright, "headlight-in-face" look that comes with unmodified on-camera or built-in flash.

I've tried a bevy of options to deal with that. A good one is bouncing the flash, but that's effective only if you're someplace where you can bounce the light off a light-colored wall or low ceiling. There also are on-flash modifiers -- a small softbox, translucent flash-head caps (e.g., Omni Bounce) and even metal brackets to get the flash unit off and above the camera. In the case of a camera's built-in flash, there's the Gary Fong Puffer. Each of those has helped get me close to what I've wanted to achieve, but each also has its limitations, and almost every one -- on occasion -- still will allow a little too much harsh, direct light on the subject.

So I was immediately intrigued by the technology used for the Graslon Prodigy, Insight and Spark flash diffusers when I read about them about a year and a half ago. From the images I studied with the stories and reviews about the Graslon products, I liked how they helped soften light, reduce the likelihood of red-eye and still gave subjects the flattering illumination I sought. I was getting a bit of that already with a small softbox attachment, but there were still instances when even that wasn't cutting it.

Two things contributed to me holding off on a decision to buy any of these -- price and the mechanism used to affix the diffusers to the flash heads. I relented early on and bought the Spark, which was designed for the pop-up flash. The price -- $35 -- was the least expensive of the three, and its attachment mechanism looked relatively safe; it slides on to the camera's hot shoe. Indeed, it has been safe, and pretty effective. I've like what it's done, but I have no control over the light intensity, and that's an issue with pop-up, with or without diffusers.

So in pursuit of the same kind of result with the two Graslon diffusers designed for flash units, the Prodigy and Insight, I continued to study reviews. The technology is commendable; the diffusers are built with a mirror system consisting of strong plastic that help bounce much of the light throughout the device then out through the top, bottom and sides, while the exterior facade allows a very small amount of direct light to escape through tiny holes.

The Prodigy is larger (8x5x3") than the Insight (6x4x3"); both are made with two interchangeable attachments, although the $90 and $63 price tags, respectively, get you only the base unit and one attachment. If you pay for one unit and an attachment, you can purchase the second attachment for about a third of the price of the full unit. One attachment is a rounded dome for use where bounce opportunities exist. The other, flat surface attachment is for when there are no walls or low ceilings to bounce light off -- outdoors, in a huge hall or where there are tall ceilings.

So you can understand the cost issue. (I found it odd that two reviewers thought the price for these was nominal and quite reasonable; another reviewer felt as I did, that they are pricey).

What bothered me more was the other issue -- the less than enthusiastic responses from buyers who bought one or the other and were not pleased with the device's ability to remain firmly attached to the flash head. (Although two reviewers claim to have had no trouble with that.)

Despite both concerns, I did take the plunge finally, and bought the Prodigy -- both the dome and flat attachments -- and discovered immediately what those users were talking about. The device uses a circular bracket through which you insert the head of your flash unit so it fits snug against the hardware. Once snug, you're supposed to be able to tighten the bracket with the plastic thumb nuts around the bracket then further secure it by tightening a Velcro cinch that surrounds the bracket. I had to try the process four or five times on my maiden use before I felt the snugness I needed to ensure the diffuser would not fall off without warning.

And I didn't get it as secure as I wanted on the first try the next time I went to use it, either. Personally, I think Graslon shortchanged customers on the quality or design concept for the mechanism to secure diffuser to flash, and for $90 and $63, that shouldn't have happened. And yes, the unit did separate from the flash head on its own once on my first use. Fortunately, it came as I was placing the camera and flash on a cushioned chair -- gravity apparently pulled on it -- so no harm done. Reviewers claim that the dominant plastic used in the mechanism is so strong that the Graslons wouldn't damage if they are dropped. I hope not.

One other note, as some of the other reviewers have noted, the larger, heavier Prodigy unit tends to be more likely to loosen or fall then the lighter Insight. But the reason I went with the larger Prodigy is because the larger and closer the light source, the softer your light will be, and that's what I wanted. Currently, Graslon offers no bag or other portable carrier to tote the modifiers, although reviewers I read say Graslon is working on such an accessory. The Prodigy, especially, is too large to fit in most camera bags without taking up most of the space. So finding storage is an issue for this (I simply kept mine on the camera to and from the shoot Thursday).

That being said ... when the diffuser is on the flash and you're using it, the light is very nice. I would even go so far to say that it has given me the best lighting on my subjects of any modifier I've used on a flash attached to the camera. I used it to take the photographs you see in this post, which was from a shoot last week during a practice of the Garfield Shakespeare Company's spring play, Thornton Wilder's "The Matchmaker."

Leading off the post is a shot featuring actresses Laura Kelley (left) and Katie Schneider, an image in which I was impressed by the quality of even light striking both cast members. That's Katie again in the first picture below, with Monica Verdouw in the background.

I used manual settings on the camera (Canon 7D) and 580EX II Speedlite. For the camera, I had my settings at f/3.2, 1/100, ISO-800; the higher ISO setting allowed me to get some decent ambient light onto objects in the backgrounds, something I wasn't getting with test shots at ISO-100. The Speedlite was set at 24mm zoom, Manual mode and a light intensity of 1/32.


Above: The light was just enough to amply illuminate Justin Monts, who is looking at a park bench in the distance during this scene of the play. 

Above and next two below: These costumed, non-book shots were taken to use for the selections to pick formal publicity photos for the show. They feature Laura Kelley, in the role of professional matchmaker Dolly Levi, and Jonathan Kratzner, in the role of wealthy merchant and widower Horace Vandergelder.  



Above: Kelley again; this time I'm testing the distribution of light from low angle. I think it did well.

Above and below: I wanted some shots without flash -- at available light -- to contrast what I would get with flash, so I took these. I looked for opportunities when cast members were in direct lights from the overhead beams illuminating wall art in the gallery hall. I pushed the ISO to 3200 for these two shots and used no noise filter in post-processing. The 7D's noise suppression at such high ISOs is something I really like about the camera.

Every picture tells a story:

Finding unexpected value

Backlighted photos you don't have the time to set up properly might end up in the discard pile a lot. But with some work and care in post-processing, sometimes you can come up with wonderful silhouettes or beautiful portraits with such images. This is a story about one such photo; the image might not be very spectacular, but it is one I'm glad I didn't toss.

I strive to shoot available light when possible, even for indoor family gatherings. I did so on Thanksgiving, and although the end result from those pictures was satisfying, I didn't arrive at the "end result" until after a lot of post-processing work with editing software. Even using an ISO of 1600 and a lens with a wide aperture (f/1.8), I still had difficulty getting enough light for optimum exposure in the living room, dining room and the grandchildren's playroom on Thanksgiving. With 150+ pictures, it entailed considerable work.

I wanted to avoid so much post-processing editing for the Christmas get-together. So on Thursday, I decided to use Gary Fong's "Puffer" light diffuser on the pop-up flash on my Canon 30D. I knew I'd miss that natural look in ambient-light photos, but the Puffer delivered decent exposures, didn't white-out people's faces from using a straight-on pop-up flash, and left me far less work afterward. Oh, it also helped that I shot about 50 fewer pictures than on Thanksgiving!

One image I did spend a lot of time on afterward was a shot of my 3-year-old grandson Jakob, who I had noticed positioned in front of bright sunshine, streaming in from a dining room window, as he examined one of his Christmas presents. I knew I wouldn't have the time to set up a candid the way I really wanted, or to shoot many frames before Jakob would move on to other things. So I simply pushed down the pop-up and fired off an available-light frame in hopes I'd have something usable.

The color picture above is the original, unedited shot. I didn't feel strongly about it, but I did notice interesting spot illumination on Jakob's cheek, nose and forehead that I thought would be worth emphasizing in a grayscale (black-and-white) conversion. So in post-processing, I made a copy of the jpeg, converted it to grayscale, cropped it to eliminate the tiny stray light on the bottom left, fiddled with the facial shadows and highlights to play up the spot facial illumination, and tweaked the contrast. I left in the two tiny lights in the right background of the image to retain some balance and a representation of the holiday. The lights were on a garland decorating a living room wall. The result of the edit is the black-and-white version you see above left.

Then I made a copy of that b/w image and recropped it as a tight horizontal in pursuit of a dramatic, moody feel (below). On the crop, only the bottom of the two background garland lights showed up, and at this tight of a crop, that tiny light became more prominent and, hence, a distraction. So I cloned (erased) it out. The tradeoff going from the vertical to horizontal crop was a considerable loss of size -- my guess is that this version will lose quality printed at anything larger than 5x7 -- but I do like the effect, and all in all, the two-grayscale copies gave me value out of an image I might otherwise have discarded.

Gary Fong, by the why, markets a variety of flash diffusers; most are for electronic flash units; the Puffer I mentioned above is for pop-ups and is among the least expensive. You can check out his full line at http://store.garyfonginc.com/ ... and no, I don't know Gary! I'm simply providing this in case anyone would like to explore it further.
