The colors and the images as a whole are wonderful. Thanks for all the posted images here. I have never used such a camera.

Thanks Raid, it's never too late to start experimenting with such a camera.

The Black Poplar trees are flowering in our neck of the woods. Can but try and get a snap with my arms stretched out above my head.

I used to have (transparent) tape on my dp2 merrill screen to be able to frame 4x3 shots:

It seemed a bit soft for a Merrill and I wondered where the focus was ...

... so I did an edge-detect followed by a threshold filter in the GIMP, voila:




I'm not real sure that edge detection shows the focal plane that well but it's kind of like Contrast Detection AF which the DP Merrill uses, IMHO.

Makes me so happy to see an edge detection image here.
I wrote my first edge detection code over 40 years ago. It ran on an $8M supercomputer.

Makes me so happy to see an edge detection image here.

Certainly an interesting subject especially with respect to focus position or depth thereof.

I'm leery, in Jeri's image, that the focus plane is perhaps not the treetops as implied - because of the big difference in local contrast between the top and bottom of the frame.

Of the various common methods (Canny, Sobel, Laplace, Gaussian difference, et al) do you prefer any with reference to image focus measurement?

Your code will probably run quite well on my cellphone ... 😉
