Hi,
Please do not mind me asking a very basic questions.
My raw files are taking up too much space on my harddisk. Is it okay to convert those raw files to jpg before using a photo editing software to improve on the images at a later time? Can someone point me to a basic tutorial if there is one on this site? Thanks.
You will lose all the benefits of RAW processing if you convert to JPEG. In fact, there's little to no point in shooting RAW if you convert directly to JPEG, so you can save a lot of hassle and space on your HDD and memory cards by shooting JPEG in the first place.
Depending on your end product (web, print, etc.), you might see little to no benefit from RAW. There are a lot of working professionals who shoot exclusively JPEG - mostly wedding photogs and photojournalists. If you absolutely need the best quality out of your photos and/or do extensive photo editing, and don't mind spending quite a bit of time in post-processing, RAW shooting and workflow is necessary.
All RAW processors will convert your RAWs to JPEG, it's usually called "export."
