How cool is that! He cooks as well as critiques! Lucky lady you've got there!
Thanks Joe, excellent explanation on jpeg vs raw. I took a raw file and the same pic PS'd and jpeg'd, and blew them up 300% - I can see a huge difference! Ok, so several more 32G SD cards need to go on the shopping list. I looked up several postings on WB, and am trying to educate myself on how to set up the best - will start on the camera's settings, and get me a chunk o'styrofoam for reference purposes.
One step at a time, I guess. Again, thank you for your assistance. Have a pleasant evening...time for me to crash, 5 am arrives at an obscenely early hour...
My wife and I are both retired but both do a little part-time work. She works some evenings and of course I fix dinner for when she gets home.
More JPEG versus raw: Before explaining another raw advantage it's worth it to say a few words in defense of JPEG. Some pros have to shoot JPEG because of the job requirements (journalism, sports for example) and they do a good job of it so we want to remember that. JPEG is of course a huge benefit for the snapshooter and makes all of our instant gratification possible.
Next raw advantage: There's so much more information in a raw file. The difference is dramatic and so the raw files extends what we can do if we're trying to take serious photos. I got the impression you wanted to take this a bit more seriously. You're not under the kind of constraints that a journalist would be under so do it right.
Last raw advantage I'll mention: It's faster and easier. If you're going to assume the need for post processing of the photos, and you should because the camera software is too limited, then it's faster and easier to achieve a good end result from a raw original than from a camera JPEG. My students know better than to say the word edit in the same sentence with the word JPEG. I teach them as needed how to do it to best advantage but the process in my presence must be called repairing a JPEG. And every time they say it they know I'm going to respond with, "why'd you break it?" It's much more difficult to repair it after it's been broken than to just do it right in the first place.
White Balance: Light changes color depending on the source. We need to know the color of the light to get accurate color in our photos. Problem is once the light is reflected off a subject it's changed by the subject and so we can't measure the light color that way. Unless of course the subject was spectrally neutral and didn't change the light color -- the piece of Styrofoam.
I took this photo a couple weeks ago:
My camera was set to auto WB and in that case the camera uses an algorithm to try and estimate the light color. You see above the camera's best effort. After I took the photo I reached into my camera bag and grabbed the Styrofoam rectangle that's in all my camera bags plus coat and jacket pockets. I took this photo:
I measured the color of the light by measuring the Styrofoam (didn't even bother to get it in focus). You get two numerical values from that measurement: temp and tint. I transferred those values from the card photo to the first photo and the difference was substantial. Measuring the light color gave me accurate color in my photo. I don't take a measurement for every photo I take just for a set of photos in a similar lighting condition so it's not an onerous task. Here's the corrected photo:
So this only works as a post processing step and only with raw files. Frankly it's easier because it doesn't then matter what the WB is set on the camera. You get to ignore the issue behind the camera and concentrate on taking a good photo. Shoot the card after you think you've got a keeper.
