What I learned this summer!

1. Luminosity and contrast rule the image
2. The wrong color is can destroy a picture no matter how good the luminosity and contrast.
3. Unchecked, my email app downsizes images
4. Lens correction in LR, and presumably ACR, alters image dimension 
5. 8 bit, sRGB jpeg is just fine for almost every image I process.
6. Channel blending might be the most important step in contrast, in the right images
7. I can eliminate a moire pattern, but maybe shouldn’t always do so completely. But there are more ways to recover luminosity contrast. (See #6)
8. Decreasing the saturation is a very important step in the PPW workflow. It was very hard to believe how desaturated I could make an image and then recover and enhance every bit of it. I have become a believer.
9. Overthinking an image correction can be just as bad as overthinking my golf swing.
10. Images like our bookend offerings are very challenging, when there are one or two dominant primary colors. Having other colors in the image can cover up my mistakes.
11. Looking at 20+ representations of the same image can play tricks on the eyes. And the order you view them means a lot.
12. The members of this group are very generous with help and explanation.
13. Outside the time spent on the weekly entries, my color correction has become quicker and more efficient.
14. Photos from an iPhone are not bad and very amenable to Photoshop color correction.
15. Don’t send an image out of Photoshop by text message before converting it to sRGB. The phone screens do not like the LAB conversion.
16. I’ve re-read about 25-30% of Dan’s books since Professional Photoshop 4th edition. There are chapters from every book that help my understanding. I can also say that when I re-read MPCW pp.222-225 Under the Tuscan Sun and could understand it!
17. In the very next section of that book, A Sad Tale of Skintone, Dan recommended not to get discouraged if you overestimate your work before you compare it to other. I’m following that advice, too. I critically injured a lot of images this summer, but I also took away a lot that improved me.
18. Knowing how to manipulate a technique is not good enough. The final result is what counts. I actually already knew that, but it is a lesson I relearn many times over, in almost every field I venture into.
19. I can’t thank Dan enough for these 11 weeks of instruction. There is so much content in his critiques of every entry, that I’m sure I will be referring to this material for a long time forward. I’m amazed every week how much there is to each image. This is a fantastic opportunity to systematically investigate a great range of approaches to correction. Most every week I spent a great many hours learning about the techniques I needed to apply. Sometimes, of course, those learning hours were spent after I saw the rest of the entries!
20. So thanks, Dan, for the great summer school. Now, back to Simultaneous Contrast of Color…
