For 100+ years, any given photo had a single prime focal point. But the results of this week's Shooting Challenge combine multiple points of focus to create images never seen before.
Before you read on, be sure to follow Shooting Challenges on Facebook to stay up to date! (OK, shameless self-promotion over.)
This is the filament of a well used quartz-halogen automobile headlamp. The area seen here is 1.54 mm wide, about the same area that you would see through a 100X microscope, but through the microscope you could see only a tiny slice in focus at once. Shot at 11.3X using a Canon T1i camera and Olympus 20 mm bellows macro lens at f/2 (effective aperture > f/22), ISO 100, 0.3 sec. 40 frames at 0.013 mm focus step (total subject thickness 0.5 mm), using a screw-feed setup. Assembled by Zerene Stacker, finished in Photoshop.
Shot with 7D and EF100mm f/2.8 Macro USM (1/200 sec @ F/9, ISO100)
I've always wanted to give a focus stacking shot a try so when I saw this challenge it made the perfect subject for my 365 Project. This one was made using 7 different images.
[Ed note: While the whole shot isn't in focus, note the multitude of water droplets captured with razor sharpness. Nice use of the technique.]
For this focus stacked image of a daisy, I took 15 images at varying focal distances with a Nikon D90 and an old full frame Sigma 70-300mm lens, set to 300mm (macro) on a tripod with a remote. Exposure: f5.6, 1/60, ISO 320. Images were then combined in Helicon Focus. Some post processing sharpening and contrasting was done in Photoshop.
Camera: Canon EOS Digital Rebel XSi
Lens: EF-S 18-55mm F/3.5-5.6 IS
Shutter Speed: 1/4 sec
Focal Length: 53mm
This shot is of an old micrometers I have. It probably around 50+ years old and works perfectly. This shot consisted of 13 images that I used photoshop to align and stack. For lighting, I used my home made lightbox and 2 desk lights on either side.The background is a piece of UV printed black foamcore.
Exposure 1/50 sec
Focal length 56mm
I was concerned too many people might use the same subject, Okay, maybe not. Used Helicon focus, an awesome program. I had difficulty with the lighting, cloudy day and the light varied a lot. I had to compensate by shooting 24 shots as quick as possible. My wife did help a little.
[Ed note: Aside from the humorous full disclosure footnote, the subject's juxtaposition against the ethereal background is a neat effect for sure.]
ISO 400 - 45mm - f/3.6 - 1/10sec
I used a home-made reversing ring in order to mount my kit lens backwards and have an ghetto- macro setup. I had to blend each focus point in manually in Photochop because none of the layers were even close to lined up.
[Ed note: I do love this shot, and I've been looking at it over and over, trying to decide if you'd need to use focus stacking to pull it off. With this exact rig, you unquestionably do. In general, I'm not positive that's the case. Still, great shot.]
My boyfriend wouldn't stop talking about this shooting challenge so I decided to humor him and used image stacking on my lunch. This series of images was taken on a Canon 5D with a Nikkor 60 mm macro f 2.8 at ISO 200. To blow out the background I covered my carpet and wall with printer paper and used a Canon EX 580 flash. Some post work was done in photoshop including curves and the clone stamp to get rid of rough edges.
[Ed note: Textures and colors for the sake of textures and colors—I actually offloaded the final verdict on this shot to many of the Giz writers, and it's almost universally loved. Also, it's a shot I'd challenge skeptics of the technique to recreate without focus stacking.]
More than ever, participants said two things of this week's challenge: One, it was difficult. And two, it was their first time attempting the technique. I love that, in spite of both these points, so many of you not only entered, but were able to prove that focus stacking has greater purpose than mere gimmick. Awesome job, everyone.
Gizmodo's Shooting Challenge is a weekly opportunity to dust off that fancy dSLR and experiment with hundreds of others in a new photography theme announced every Wednesday. May the best shot rule the internet for a week!
