Below are my camera LCD screen captures for these adjustments. Note I use Canon 5D Mark III so the menu could be different from yours, but most of these settings are available in other DSLR cameras.
1. Set your image quality to RAW
Jpeg format is compressed and contains much less information than RAW format files. Even you are not keen on post processing right now, shooting RAW format will give you flexibility to restore information for any important photos you take. In particular, those photos are about the places and moments you see only once in a life time.
On the flip side, RAW files are much larger. For example, a RAW file produced by my Canon 5D Mark III could be around 25MB, but its Jpeg equivalent could be only 5~6MB. Therefore if you don’t have enough storage space in your hard drive, or you don’t have enough space on your camera’s memory card, shooting Jpeg is a wise solution. But if you care about photo quality and want to have the flexibility to post process your image, you want to shoot in RAW.
This following screen is for cameras that have 2 memory card slots. Although mine has two, I never used two memory cards at the same time, not because I don’t have two cards, but because I don’t think it’s necessary. I’m especially against saving RAW and Jpeg files at the same time, although it sounds like a great way to backup photos – you keep two copies on two cards, in case one is lost, you have another. The fact is: if you only care about RAW files (like I do), an extra copy of Jpeg files is useless. I keep a simple workflow of importing my RAW files into hard drives and back up my hard drive frequently, as my backup system.
Some people might think keeping a copy of Jpeg files can save time in case they need quick delivery. Well – if your post processing time on each image takes no more than a few seconds (like in my case, see this video tutorial for my post processing), and the retouched photos from RAW files look much better than their Jpeg equivalent, would you still bother to shoot Jpeg, even as a backup?
