Thanks all. I can and do use LR to process RAW pics with varying degrees of success. My assumption was that Jpeg would do the "heavy lifting" so to speak and then I could tune it up in LR.
Thanks again
It turns out that's not a safe assumption.
When the sensor records the image, the image is in memory as a RAW file. At that moment in the time the camera has all of the "information" associated with every single "pixel" on the sensor (color sensors don't really have "pixels" ... they have "photo-sites" which is just a single R, G, or B component that will eventually become a pixel once it is "De-Bayered".)
If you tell the camera to save in RAW format then ALL of that information is saved.
If you tell the camera to save to JPEG then a few good things and one very bad thing happen.
The good: The camera applies changes such as white balance, de-noising (if shot at high ISO), sharpening, saturation, etc. In other words it does a lot of the "heavy lifting" the needs to be done.
The bad: The camera also "compresses" the image to save space... but it's worse than that. If I have two adjacent pixels which have NEARLY but not EXACTLY the same hue or brightness then JPEG will decide it can save space by "normalizing" those two pixels so that they are, in fact, exactly the same color (not just close). If this were a RAW file, they would be stored as-is with no adjustment. Where this gets painful is if you had detail (typically this is worst either in highlight areas or shadow areas) and you need to adjust the exposure to recover that detail. If you shot RAW you'd find that the detail is still there. But since JPEG normalized all the pixels because it figured your eye would never notice the difference, then when you try to recover the detail you will discover that the detail is gone... and I mean forever (there's no way to get it back.)
While EVERY image in RAW needs at least a tiny bit of adjusting... it turns out programs like Lightroom automate that process for you by creating a "camera profile". They know, for example, roughly how much sharpening or saturation, etc. should just automatically get applied. That means when you import your images, they come in and are stored as RAW files on your computer, but then Lightroom generates a few automatic adjustments and applies them for you (without you even asking) to make them look roughly about the same as a default JPEG would look. Except that since Lightroom actually DID save the original RAW data, if you don't like it's default adjustment you CAN still still change. If you shot in JPEG your options become limited.
For this reason, I consider RAW to actually be EASIER than shooting in JPEG because the image processing software does the heavy lifting for you -- but doesn't destroy the original data from the file and THAT means that ultimately any adjustments you need to make are actually possible. You get substantially more latitude to adjust a RAW image and you don't have to fight to get the change to happen. Had you shot in JPEG... it fixing an image can be quite a struggle if you needed detail that the camera has long since discarded.
