Being a novice to raw files, these converted files have two different compositions. Bridge 3 photo was shot with a Canon 80d with a Canon 17-55mm 2.8 at 160 sec, F8, ISO 250, 55mm. Bridge 10 same camera and lens at 160 sec, F10, ISO 650, 21mm.
Any comments would be welcomed. I hope these are relevant questions for this forum.
I don't read a question Rob, but I think I know what you are getting at here. This seems to be a new adventure into the raw picture capture and now you just need to be pointed in the right direction.
If you had take both of these in both raw and jpg, you could compare the pictures on your computer screen. You'd probably note that the jpg looks better than the raw and you might even think "what the heck" I thought raw was supposed to be better. Well, in a way it is but not straight out of the camera it's NOT.
Think of a raw file as all the ingredients of a cake thrown into a mixing bowl but not mixed up much, while a jpg is not only mixed but it's baked and yummy right out of your camera. To make the raw file yummy you have to mix it, blend it, maybe modify the ingredients slightly, and then bake it but bake it very carefully so that it's just so. Then and only then do you have a better cake or file.
What I'm saying is that the raw file has a lot of data that can be manipulated until you get a better result than the jpg. But you have to be the one that process it on your computer with a good software program. Just so you know, ALL raw files require at least a little sharpening. They all need a little contrast, saturation, highlight and shadow adjustments and maybe a little w/b adjustment to make them as good or better than a jpg. Then you still have the latitude to work more on the image to make those clouds more dramatic, or the wood grain pop, or the water more turquoise or blue or the sky more blue or less blue if you like it to be as you saw it the day you took the picture. You can really make major adjustments without the pixels falling apart since there is more data. A jpg is only an 8-bit file, so it has about 1000x less data to work with and if you want to make a really dramatic change, the pixels will not look right and the image falls apart.
I hope this makes some sense. If not, take a picture with your camera of a scene with a dramatic sunset or dramatic clouds and set it to capture both jpg and raw. The on your computer make a major adjustment to both pictures and see what happens to the jpg vss the raw file. It will make more sense.
Not everyone needs to shoot raw. Jpg pictures for the most part if taken at the correct exposure are fine to look at and print. But there are cases where the photographer wants to be in control of how each picture comes out and have the data to make a big change to the image without it falling apart.
