  1. A 2-shot focus merge working absolutely beautifully in creating a sharp image meeting my vision for the shot. I used luminosity masking to help in the edit - to separate water from reeds.
  2. Another one. The clematis flowers have all started going to seed, and some of the heads are getting quite fluffy. I'd intended to make another merge or two, but the camera battery ran out! Technical stuff: Canon EOS750D camera, Canon EFS 60mm (96mm equivalent) macro lens, f/2.8, ISO 1600 (because I forgot to set it to 100 before i started!); thirty photos. I have the camera set to save CR2 (Canon Raw) and jpeg; for quickness, I made the first merge from the jpegs straight out of camera then adjusted white balance and vibrance, saved the afphoto file, then reduced the size and ever so slightly sharpened the image. (For some reason I get an error trying to upload the first file, but this slightly compressed version works.) Although I set the white balance and vibrance to give what i thought was the same result, as you see the two pics are quite different. I think I prefer the first one, but that's just me. And maybe a more contrasting background next time?
  3. Situation: stack of 52 images, static subject, used focus rail to achieve focus with increasing sharpness to objects/edges farther away Camera: Nikon D5100 with El-Nikkor 50mm (enlarger) lens mounted backward at f/5.6, 1/20 second. Affinity Photo 1.10.0.1127 Since I know little about stacking in Affinity Photo, I used only defaults. The stacked result is soft (photo with center in focus), while for example, the sharpest petals surrounding the dahlia center (photo with unsharp center) is found on one of the middle images in the stack. I experimented with the various types of stacking but did not find one that appeared to actually select the sharpest petals consistently. How can I achieve that sharp-sharp focus stack result?
  4. Now that Affinity Photo is using the GPU in 1.9, I'm getting errors which are probably due to this change. The first time I was trying to stack images, I was running another program, DxO's PhotoLab 4. which also uses the GPU. I had various results: a hang (had to reboot), a hang (was able to kill the program), a black screen that reset and sometimes odd results. And sometimes it works. I just tried the same focus stack three times, once with PhotoLab 4 open but inactive and one without but with Affinity Publisher open, and one with neither program. Twice I got incorrect results. The third time, I got a black screen and the program hung (I was able to kill it). It might work if I reboot after using PhotoLab 4. I've attached examples of the two focus stacks (the results ought to be identical). Here's the info for my graphics card. I did install the latest driver before checking all this.

  5. It would be very useful to be able to save also the different sources used in the Focus Merge function, to be able to make the often necessary corrections (halos, alignment errors, ..) in multiple work sessions because it may not be possible to complete the work at the same time.
  6. Focus stack from 180 jpg shots, all post done with Affinity Photo
  7. I love hiking through the great southwest and taking many thousands of snaps, mostly of landscapes because my damn DSLR lens won't focus on small stuff. I recently threw my worn-out camera away and replaced it with a "toy" iPhone XR camera and three Moment lenses. Now I can take home some high resolution photos of small (even tiny) things that don't move while I'm shooting at them. That's better than nothing, and I don't have to carry around several thousand dollars worth of heavy photography equipment. If there is any interest I will describe in detail how I use CameraPixels on my iPhone XR to focus bracket up to 50 images and Affinity Photo to focus align and merge the images. There is a wonderful world of macro photography right at our fingertips, and it doesn't have to cost thousands of dollars. This first image below, about one cm across and one cm deep, was taken with a Moment macro lens attached to an iPhone XR mounted on a tripod. CameraPixels was used to focus bracket 40 images, and Affinity Photo was used to focus align and merge the images as well as remove a halo around the petals. The third image shows the sexual part of a bright red geranium flower taken with the iPhone XR and Moment macro lens. Moment claims a 10X magnification from this lens, and I've verified that with a ruler. Imagine looking at a three to five inch cluster of bright red geranium flowers and staring into a single flower that is about 3-5 cm wide. What you see in this third image is the reproductive part of one of those flowers; the image is about 2 cm wide. Look closely at the detail in this image. See the tiny piece of fiber stuck to the pollen on one of the stamens? The middle image was clipped out of the right image in Affinity Photo and expanded using Bicubic Interpolation. We can clearly see the individual pollen particles. This is over a 50X magnification!
