Guys if anyone knows about this, does shooting in raw help the highlights and exposure? (With or without editing the picture )
I've tried shooting in raw but they look almost the exact same as my jpeg files. How is this so?
You do get more control with RAW because you're using the data straight out of the sensor before any automated processing. You get more contrast, highlights, shadows, and exposure control steps because nothing has been compressed yet.
A RAW image isn't directly viewable. It's like looking at the lines of code in a program. The info is there, but you can't make use of it until you run the program. In our case, you need a special viewer to see, and edit, RAW files. If you are using the stock gallery app, you'll see the jpeg that was also created like a normal saved picture. It will show a DNG notation on it to indicate an associated RAW file, but it's not the RAW file itself you're seeing.
You'll need something like Snapseed or one of the other editing apps capable of using RAW files, or an equivalent on a computer to do so. When you open it on the editor app, don't be surprised if it doesn't look the same as the associated jpeg, because it hasn't been put through the automated converting process that the jpeg has. The camera app applies various filters and adjustments to the RAW file itself (which is usually discarded unless you set it to save as RAW) when creating the jpeg to attempt making it look more real world.
Another question haha, I just deleted a raw photo, but when I check smart cleaning it still says I have raw files on the phone. So basically deleting the raw photo will not delete the raw files? I'm confused
If you delete the photo via the stock gallery app, I'm pretty sure it's supposed to delete the RAW file as well, even though they are two separate files. If you are deleting from a third party app, chances are it's only deleting the jpeg image. In this case, you'd have to use a file explorer to delete the DNG file, or the Smart Cleaning tool like you mentioned.
One last thing, how do u view the raw files other than in photo editing software? Can you view their sizes in file manager?
You can view file info in a file manager, but not the EXIF data that tells you what camera was used, resolution, exposure, etc. As I mentioned above, you'll need a dedicated editor to view them. There are no RAW viewers that I know of that don't act as an editor. That would actually be misleading in a way because most people don't realize that RAW files aren't a finished product like jpegs are and give them a false impression of the camera's abilities.
