Don't know if this will appeal to ya Mikey, but here ya go just in case :-)
I had a great shot of the sky ruined by my not so great skills with a camera. Its been cheesing me off since I saw the result. Thought to myself, " There has got to be some use for this" So here ya go.
I took this original, which I think is full of lines due to not letting my camera adjust to the temperature ???.
To get rid of all the lines I took it into Corel Photopaint5, yup its a golden oldie program, and simply set my merge tool to 117%. This means I set it low. I then proceeded to ask the program to merge the image with itself, blend is another word.
After asking about 7/8 times the image was practially clear of the lines. I set it low so that it made subtle changes many times, and not drastic changes a few times. This allows the merge process to anti alias the image without too much distortion.
After getting the image close to "line free" you can start to put the detail back in. I do this by using the Directional Sharpen feature. This again applies subtle changes to the detail level without over compensating and distorting the image to something else. Again use settings just above NO CHANGE and use them many times, rather than quick fix drastic changes.
Image 1 is the start. Image 2 is what it became after the above tweaks.
