  1. That's what I was trying to do as well 'gdenby' - thank you!

    Unfortunately, most of the pictures I have is already B&W.

     

    One of the versions from high res pic:

    Also, I ask Simon Foster (author of the AP Udemy courses) for help, and he was kind enough to provide one of the techniques that one can use as base/macro:

  2. I think the basic reason you got a pixelization is that the image is too small. Too few pixels to begin. And it had lots of .jpg artifacts. I don't know how to resample the image w. AD. I would suppose AP would do that. I tried some medium sized images, about 500 px on a side. Had similar results. Resampled them in GIMP to about 1800 px.

     

    After using threshold on the placed resampled image, I had much less pixeliness. Worked better if I placed them rather small, applied the threshold adjustment, and then scaled them up. Got smoother blobs. Oh, and I was using the luminosity blend mode for the threshold adjustment.

     

    You might also try posterizing to 2 - 4 levels, and then adding B&

    W adjustment. That way some of the similar color contours in the original pic might be preserved.

    Thank you, gdenby!

     

    I also tried to apply Gaussian Blur after the threshold and had similar results.
