    RogerWehage got a reaction from muggooz in Any Interest in Macro Photography Using an iPhone?   
    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!

    RogerWehage got a reaction from KipV in Mac Photos Extension: Affinity cannot be launched   
    Here it is 2019 and this problem still hasn't been fixed. Normally I'd have switched over to Luminar by this time but it doesn't work correctly with Photos either.

    OK, I did find that in Photos I can choose Image->Edit With->Affinity Photo and Affinity Photo will be launched with the selected image in Photos then opened in Affinity Photo. If this is the way Affinity Photo was intended to be launched in Photos, then Affinity Photo should not be included in the Photos extension list, which can only lead to confusion.

    If the image averaging process is linear it seems that one should be able to divide a set of images into a few groups and first average each group. Then average the resulting set of averages into one final average. Has anyone done this or is there some reason why this would not work?
