After working on old photographs eg. cloning, levels, brightness etc. the image gets steadily worse in definition the more I work on it even though I've kept it on screen and not been saving it. I've tried working in different formats. If anyone can tell me why this is happening and give me a solution it would be much appreciated.
Thanks to you all for your help.I'll get the mag.Sorry i havn't got back to you but i had to flatten my pc & had some hassle.I use photoshop7.Now I am using tiff which seems slighly better,not being compresed, but still losing definition.It seems to me that the tools, ie cloning have a sort of aura that reaches further than the eye can see.
Les there's not much point in using any other software, you already have the best. are you by any chance using the sharpening tools, as this will create problems for you, also what about the opacity and flow setting when cloning, try them at 100%.
If you are keeping it on screen I don't think it matters much wether you work in Tiff or Jpeg.
Les2 - I work in photo restoring and am active here : click here. This site has more than you can imagine and the folks are more than willing to give advice. To me it sounds like you are doing all your work on 1 layer. It is best to do all your different restoring on individual layers. Set your tools to very low levels and change opacity of layers to see if there are changes to your original. when you clone or heal, you are actually smudging pixels, but you can limit the amount of damage by adjustting levels and options. If you go to the site, attach a copy of your work so we can all see what you need to do.
