Re: Diagonal stripes (scrapbook glue)
Very Q&D, more proof of concept than anything else.
Box blur to remove dots
Dupe layer and set to lighten blend mode
Move down to remove stripes
Mask out eyes, outline of nose, lips to remove introduced ghosting
Mask out hair to remove duped dust specks
I spent like 3 minutes on it, I suspect you could do much better. Post back your results or if you find a better way.

Re: Diagonal stripes (scrapbook glue)
It's a bit tedious, but I had some success with the healing brush (not spot heal).
Box blur to remove dots (your sample called for 2px)
Set healing brush to lighten blend mode and size just a tiny bit wider than dark stripes
Set source point in light area next to beginning of dark stripe.
Click once on start of dark stripe, then hold shift and click on end of dark stripe
Inspect and undo/redo if necessary (it will be)Learn by teaching

Re: Diagonal stripes (scrapbook glue)
I've got image analyzer. I'm curious which pattern in the frequency domain you painted out. If I select the pattern on the white paper I can fairly easily eliminate the pattern in the filter but when I do the image as a whole I'm having a hard time figuring out what to paint over.

Again, when I isolate the pattern on the sides and display the Frequency Domain, I can see two white lines towards the top of the frame. If I black these two out I completely eliminate the stripes. However, when I display the entire image I cannot find the same two stripes to cover. I'm trying to learnAny guidance would be much appreciated

The 2 points on the top are causing the lines.Attached Files

Re: Diagonal stripes (scrapbook glue)
chillin I'm not sure if it makes any difference but it appears you are using a different version of Image Analyzer than I am. In my frequency domain filter it says "amplitude scale" rather than "view scale" and only seems to brighten/darken the spectrum rather than zoom. I'll post a screenshot.

by twinkissedI've been trying just using clone and heal brush with no luck. This is from a feather boa and then part of a belt buckle. It's only a portion of the photo. It looks as if every place that would have been black or dark brown if it hadn't been in sepia now has these light brown spots. The reason I say...

by jeaniesaI know there must be an easy way to do this, but my mind is drawing a blank right now. A client has requested that I "remove" the dark hair on this arm. Can anyone give me some tips for the best way to do this?
Thanks, Jeanie...-
