I often get asked ‘How do you do that?’ when I show someone a picture with off camera flash, and of course I am more than happy to oblige as I love to talk camera geekery. I have always been keen on off camera flash, I have practiced it a little bit at home, but I don’t claim I’m a guru on the subject, I just love to have fun with different photographic techniques. In this article I’ll talk about the vision I had for the photograph, the trial and error, the equipment and technique as well as the retouching on a series of images I took with the awesome Nicole and Billy. More after the jump (Click on the title).

The subject matter isn’t the most exciting for some, but for some Strobist enthusiasts (people who love to photograph stuff with off camera flash to a point where it is nerdy) this stuff is great! The setup for this was relatively simple and can be achieved with manual flash or ETTL, wired or wireless. I used a combination of wireless manual flash and ETTL flash that was connected to a 10m (30ft) cord and controlled from the camera body. The purpose of the job was to photograph a car radio installation kit in a new Holden Captiva (aka Chevy) and steering wheel audio control interface kit. The images will be used in an industry brochure that is designed to announce the product’s introduction.

Now for the process: With no clear direction for the shots needed, I decided to shoot first and ask questions later and the client was more than happy with the results that I showed them on the back of the camera as I shot the job. The middle shot was photographed first using my Tamron 17-50mm f2.8 lens set to manual focus, 50mm focal length and f8 for good depth of field. Ideally this sort of work is photographed with a medium format camera and a tilt shift lens in a studio but I don’t have $50k worth of gear at my disposal. The tilt shift lens would have been used to match the product plane with focal plane of the camera to maintain perfect sharpness. I still got it to an acceptable level due to the size it will be printed at. I first determined a base exposure of 1/250th of a second at f8, ISO 100 to knock out the ambient light from the skylights in the warehouse where the car was located. With no ambient light to worry about, I built up the light bit by bit until I got good coverage and balance. First I setup one Canon 580EX-II speedlight on a stand and firing into a soft box to soften the light with an additional Stofen diffuser on the flash head. Here a battery pack and am ETTL cord can be seen.

I fired a few test frames to get the lighting right by using a few different positions through the windows and checked the results on the LCD of the camera. I was getting heavy shadows cast by the steering wheel over the focal point of the photograph, the radio fitting kit. I had to fill the shadows somehow, but I still wanted good contrast and blacks to suit the style of brochure that it was going to be in. First thing was to try bouncing the light back into the shadows, but I didn’t have a reflector with me. It wouldn’t have been any use because it would be too big to fit in the car anyway. I scoured the warehouse to find something white and I found an empty white cardboard box which was perfect. I first tried a small section but it didn’t do what I needed to do, so I had to result in using another flash to get more kick. So I rigged up another Canon 580EX-II flash on a table stand, a Stofen diffuser and a radio trigger to pop the flash during the shutter sequence. This I bounced into a larger sheet of cardboard with the flash mounted on the centre console to create a larger source of light to make it softer. I then experimented with power levels until I got the right balance of light and shadow. You can see here the flash is flagged with a piece of foam (a very commonly used piece of equipment in my bag) to prevent lens flare.

The high tech reflector

I took the photographs on a tripod to slow down the process in getting a good composition and to maintain maximum sharpness in the final file. I also used a suedo HDR (High Dynamic Range) technique on the wide shot of the dash as the shutter speed was too fast to record the lighting on the dash, so the only way to soak it into the shot I turned the flashes off and shot at 1/40th of a second to register the low light output of the dash lights. The two shots were combined in Photoshop and I merely combined the layers and used a mask to paint in the lights. I also used that frame to add more depth to the photograph as the top of the dash was totally black and it needed some life. All photos had to be prepared to a printable standard in post production, so the images had to look flawless. In order to keep my retouching time to a minimum I cleaned the car in the front top to bottom with a good quality cleaner and a towel. Once that was done, I used the air gun in the workshop to blow off any dust on the product to make my job of cloning out the dust specs much easier. I used some layer blending techniques to brighten and darken certain areas to highlight the product better. The image on the navigation was superimposed on the system as it never looks good if you try it in camera. I added a slight gradient of white over it to resemble the glare from the light source.

Well I hope someone got something out of this article as it was a lot of fun to shoot. Feel free to leave any comments or questions.

Welcome to part 2 of my photo critique series. I have dug up a photo from the archives from my first ever wedding that is one of the client’s favourites of the day.

Sarah & Geoff out the side of the Royal Carlton Exhibition Buildings, Melbourne

 This kind of image had to be created, unlike what most people call ‘photojournalistic’ or ‘reportage’ style when you shoot ‘as it happens.’ My vision for this photograph was to have the side of the building as a feature and to frame the couple somewhat with the door frame. To flatten the perspective I needed to use a long lens (in this case it was taken with a 75-300mm lens) and take the picture from a fair distance back to get my framing right.

The camera was mounted on a tripod to stabilise the wobble from the long lens as this was taken on the shade side of the building. The sun was particularly harsh at that time still so I put the couple in the shade which flattens the tones quite a bit rather than having deep shadows.

The couple’s directions were simple, I said just to take a seat and talk amongst themselves while I set up the camera. This is so they felt relaxed and weren’t really camera aware, so I waited for the opportunity when they went for a kiss. On the day I tried different crops, orientation and even used shorter lenses up close, but this one worked the best.

If I was to take it again, I would move the couple to my right a bit and up a step or two to centralise them more with in the door frame and the reflection from the fountain would have lit them up a bit better too.

My post processing was quite in-depth as well, back in the days I had more time to fiddle with a photo in Photoshop. I first used a ‘Screen’ Blend Layer using Curves and painted away the mask around the couple. This brightened them up a bit to ensure they were the focal point. I then used on a duplicate layer a Shadows & Highlights adjustment to reclaim the details in the dress and to boost the darkest shadows. The rest was done with Nik Color EFX plugin to further enhance the image to give it more oomph. Here a details enhancer layer was introduced to boost the building’s details and the warming filter was used to give the image a golden glow.

Once flatten it was printed on Kodak Endura Metallic paper and mounted on Archival Grade Acrylic for an ultra modern picture mount of which I have a sample of. Feel free to comment and give feedback, I’d be interested to know what you think.

It’s always exciting bringing home a new baby, this time a used Canon 200mm f2.8 L MK1 prime lens. This lens is regarded as one of Canon’s sharpest lenses, probably just sitting behind the 135mm f2 (which I’m sure to obtain one day) and up there in quality with lenses worth six times the amount. I’ll be giving it its first test drive at a wedding next week, but initial testing at the store at f2.8 gave excellent results and a lightning fast focus speed. Not having Image Stabilisation I’ll still need to keep the shutter speeds above 1/200th of a second to shoot hand held. Here are a couple of pictures.

The Flashes have arrived

October 4, 2009

One thing you would know about me if you were a reader is that I’m into using flash photography. I mainly try to get the flash off camera as the light is always more interesting. Up until now I have been using to Nikon Speedlights in full manual mode as slaves using a set of modified Gadget Infinity wireless triggers to set them off during the exposure. I did get to the point I could guess the exposure roughly and tweak it by chimping the LCD display but that always wasted time and precious battery power.

Now I have two, yes two 580EX II Canon Speedlights so now I can use E-TTL metering on and off camera via infra-red, so I can make adjustments right from the camera mounted flash. If business is good I’ll add a third to the group and sell my Nikons. If the range of the speedlight’s signals are too short for the job I can always set to manual and use my wireless radio triggers.

I’ve already got myself another radio trigger, some Stofen diffusers and Velcro cinch straps to attach any light modifiers. I’ll need to devise a system where I can use a flash on camera with E-TTL as well as a radio trigger mounted to the top and connected to the PC Sync port on the side of the camera.

When I get to chance to play with these babies, I’ll post the pics.
