![]() ![]() Times shown for MBP M2 Max are estimates based on 2021 MacBook Pro M1 Max. Correct figures cannot be obtained since the test machine is no longer available. There are quite a few focus stacking software available, some free like CombineZP, some expensive like Adobe Photoshop, and some kind-of-expensive like Helicon Focus. Focus Stacking Using Zerene Stacker Stack 1. UPDATE 2023-0501: results are invalid for the 2022 MacBook Pro M2 Max because Interpolation = Lanczos 8 was used in Intel machines (very slow) and something else (unknown for MBP, probably Lanczos 4). Basic idea of focus stacking is to combine narrow depth of field of many images to one large depth of field in the final picture. The 2021 MacBook Pro M1 Max is stunning! Consider that most Mac Pros will have 8/10/12/16 cores and that means the MacBook Pro would easily BEAT them. It’s only about a 10% time reduction for the smaller job. The 2021 MacBook Pro M1 Max dusts the 2020 iMac 5K and 2019 iMac 5K.Īt best, the 28-core Mac Pro ekes out about a 19% time reduction over the 2021 MacBook Pro M1 Max. Zerene Stacker DMAP: focus stack 20 X 150 megapixel and 28 X 45 megapixel 16-bit TIF. See for example Nikon D850 'Focus Shift shooting' feature for Easy Focus Stacking.

Zerene Stacker is outstanding at using all CPU cores. Zerene Stacker is not the fastest stacking software out there (see Helicon Focus results), but minimizing touchup work is far more important and that’s where Zerene Stacker shines by yielding results that minimize the need for retouching and my retouching time is far more important than the computer time. With access to experts.For my photographic work, I use Zerene Stacker heavily for focus stacking and it takes minutes to do some stacks, so speed here matters. Helicon may be better suited to larger subjects while Stackshot/Zerene is better suited to the smallest subjects. Stackshot and Zerene leave the lens focus ring as is and physically moves the camera instead. Helicon electronically twists the focus ring on the lens for each new exposure. Helican was full of bugs two years ago when I used it. Now run gimp on stk-filename.tif to make the final image. It's convenient to name stacked tifs as stk-filename.tif Now save as a single stacked *.tif, named what ever you like. Using the Lightroom plugins for Helicon, Zerene and direct to PS, I find it so easy to load 100’s of stacked images directly into photoshop, select and use the plug-ins and then return to PS for editing and/or exporting to PS. Align and stack all tifs as per various GUI options. Now run Zerene again on all tifs (ZereneStacker.sh *tif). That command also deposits each *.tif file in the tiffs directory made above. That performs the same rawtherapee editing steps, as defined in the pp3 file, to each raw image in the stack, converting to *.tif on the fly. Rawtherapee-cli -o tiffs -p now.pp3 -t -Y -d -c. Save a *.pp3 file in the current directory, perhaps named as now.pp3 Edit any one raw image from the middle of the stack with rawtherapee. You now have N raw exposures in the stack all exposed and lighted identically. Zerene controls it all from that point on. Click the mouse appropriately to tell Zerene where those points are. My Nikor 105mm macro lens seems to like F8 best.ĭetermine closest focus point and the furthest. Use trial and error to determine the ideal manual exposure. Once all the various parts are wired together properly (takes some effort to figure it all out) I fire up:ġ) entangle tethered directly to the camera andĢ) Zerene Stacker, which has a GUI interface for controlling the rail-all of which I have mounted on a tripod in front of a light tent. I've worked with both Helicon focus and the two-part combination of a Stackshot rail paired with ZereneStacker. ![]()
