Description
CLICK FOR FULL VIEWThis small barrel cactus was about the size of a softball. I got as low as my tripod allowed to have the cactus as close to the lens as possible. I then shot eight frames at different focal points and blended them together for extreme depth of field. I have been trying to work on this technique with some recent images and have found it take quite a bit of time during the processing. I hope I am able to get the timing faster and work the technique more effectively in the future.

Interesting perspective, the focus blending looks flawless here, I would enjoy seeing the print you are having made of this image! Strong composition with interesting juxtaposition of elements while keeping a level of movement throughout the photograph, looking forward to seeing more of your work!

Thank you! I can't wait either, just trying to find the right printer for the job.

Thank you! I can't tell you how much that means to me! Keep up the great work, it is always interesting to see someone else at your same age in the same field of work, but in another area. We will have to trade spots at some point in time!

That's one funky looking ball of vegetation.. Nice and sharp too, nice one.

Interesting. In situations such as these, I've given up trying to use the pinhole camera effect to maximize deep focus. The best means of getting real DoF for landscape photography is the use of TS lenses -- tilting toward the foreground as to change the shape of the plane of sharp focus. Still, with smaller formats, with the sacrifice of FoV, you do gain more DoF, which leads me to believe that, if you did your hyperfocal calculations with respect to your circle-of-confusion, you could nail the same effect in one shot with similar, if not equal quality.
I've used Helicon focus, but it seems as if I used full-sized .tif files that I'd meticulously prepared, so DR and color weren't too much of an issue. It was pretty slow, however, with each image in the set weighing in around 500Mb.

Yeah, the file sizes tend to get fairly large. I would have loved to use a TS lens if I had one, I think when I switch over to full frame I am going to get one. I never hear anything bad. For printing purposes, I have found this to be the best for detailed images. I have a 20x30 print in my room where I used a small aperture and using the hyperfocal distance and the foreground was just a tad soft as well as the distant background. I'm getting this printed the same size to compare quality, but so far, blending has been the best fit. I won't use it for everything, just when I get super close to my foreground subjects. I suppose it's just a personal preference.

Nice one, man. Good composition, great lighting, and just enough detail in the mid-tones. Very well-done. What did you use to stack your focus bracketing? As you're likely well-aware, changing the focus naturally imparts subtle changes in perspective, so getting it "right," if you're not using automated software, can be a pain. It's a process I've used before, but I have trouble seeing its worth for 35mm/APS-C sensors. I'd imagine your result would be almost indistinguishable from having shot at f/11 (yes, I know about single-slit diffraction, but I tend to wonder just how evident it would really be).
Awesome shot. Keep it up.

Thank you! All of the blending is done manually, it is a pain, but I find it to be the best to ensure everything can be sharp. I have been working on it for quite some time so I am able to get it done a bit faster each time. I have used helicon focus before but if your trying to blend for DOF and dynamic range it messes it up, everything has to be the exact same. Even if I shot at f/11 or smaller, the background would still be out of focus. I had taken a few shots before changing the aperture with the same comp and even when zoomed in the background was just too soft. Would probably be ok for a web image, but I'm getting this thing printed and the details from the blend are not even comparable. It's a technique that yields great results especially if you like to get super close to your foreground subjects (Like me).

Wouldn't it have been easier to just crank down to a super small aperture? Either way it's a fantastic shot.

Thanks! That would have worked for this web version, but when blown up large you would be able to tell that the background was out of focus. Because I was so close to the cactus in the foreground, I had to blend because even the hyperfocal distance would leave one or the other soft.

Nice work. The foreground and background are so sharp.
