    Fuzz--

    I learned several things. I think the most important was the idea of using white/mid/black points more once and spread throughout the processing sequence. I had always performed white/mid/black point processing first and never thought about using it again.

    Your "4 points" are also very valuable to me. I have always tried to keep the important parts of the image in mind, but you made it much clearer to me.

    Thanks!

    It has indeed been very helpful, and I for one would very much like to see you explain layer masking and so forth.

    I think that Gimp handles masks and layering and compositing pretty much like PS; at least I was able to translate a PS gradient removal masking process into Gimp-ese with fair success. If you describe procedures in Photoshop I can probably figure out how to do the same things in Gimp and/or Cinepaint. (CinePaint seems like a super-gimp for power users who know gimp thoroughly; it's very similar in GUI but a lot more cryptic in operation, lean and mean and not overly helpful; it thinks if you are using it you must know what you're doing.)

    Ask, and ye shall receive (hope you have a LOT of time): Advanced processing work-flow (layer masks, multi-exp composite, history brush)

    So in other words, it's just like Photoshop?

    I see what you say about cumulativity of Lightroom processing - it's possible to cancel some change, but reapplying it in different sequence gives you different effect. True.

    WOW! And I thought "manually" guiding through the eyepiece (old school film days) was tough! I am completely lost on this. All of these steps are like a new language to me? It makes me feel like a 1yr. old,I'll need someone to actually hold my hand and push buttons for me! Or just piggyback for 30sec. and "shop" the single pic with the on board "enhancement" page! Man do I feel dumb!. Thanks for letting me vent a little. You guys are great!..Regards. JMR

    Heading to my local Powell's bookstore to pick up Photoshop for Dummies... I've always avoided editing digital images but I think the time to start learning has finally come. Great post.

    Nice tutorial but I wonder if it has been overprocessed. Did you notice that the dust trails are all vertical? Dust trails, well smudges really. But vertical nevertheless.

    Now look at this image, it appears to be of very high resolution and the dust trails are fine lines in any direction but not the same as in your result: http://www.utahskies.org/image_libra...1_wiyn_big.gif

    So, I wonder if some part of the processing software that you use has introduced these vertical smudges that are not real IMHO. Otherwise, thanks for the tutorial it is really educative, regardless.
