After Peter's comments. I decided it was time to learn how to use the photo editing software that I have--so took myself by the nose and went to work. Some results--compare them to the un-restored shots posted earlier and tell me what you think.
These are much better, Roy. You're getting the hang of it nicely.
The second picture looks a bit more awkward than the others. It looks as if it has too much contrast which has 'posterised' the plane. The blue sky is also far too deep a shade of blue.
Try doing another 'save as', go to RGB Levels, if you've got that on your program, or something similar whatever you have, go to the blue channel and lighten the blue - play with ther middle and left-hand sliders. Then try lessening the contrast to get the plane looking better.
This may also affect the blue sky, so you may have to play between the two to get it right.
Keep going, and keep posting these memories.
PS. Just realised you have an older version of PS. I had that version once but I can't quite remember all the features of it. Do yet another 'Save As', try going to 'Image -> Color Balance'. Choose the blue channel and play with the sliders to get the blue a lighter shade. Then go to Image again, choose 'Contrast/Brightness' and play with that. Once again you may have to go back and forth.
When you've got things about right, go to 'Filters -> Sharpen -> Unsharp Mask' and play with that. Don't overdo it though. Try somewhere around 50%, 1 pixel, threshold zero for starters.
Not the easiest of pictures to edit. Keep trying and you'll soon get the hang of what the various features do. Good luck!
Just compared your latest version of the A20 making smoke with the first posting you did of it.
Oh boy, what a difference. Well done.
Just goes to prove that unless you're into the really high-end graphics you don't need all the features of the latest versions of Photoshop. The older versions still do the biz.
Now you've got another problem - you'll be going through all your old transparencies looking at them and thinking how you can take out any colour casts from ageing or any marks and scratches to improve them. Then you'll look at old prints in the family album ...
It can become addictive. You'll look at the clock and wonder where all the hours have gone.
Good to see an old dog doing new tricks and doing them well. I really agree with Peter and find PS Elements 2.0 good enough for most of my stuff. There is still more than enough to learn with that relatively simple software. Heck, even Picasa 8, which is free, does well. Those slides of yours are really worth the effort.
