From RAW to Jpeg – an in depth look – Photoshop tutorial
Thursday, October 15th, 2009This is going to be a fairly long one so I would make sure you have some supplies ready. Maybe a snack on stand by and your favourite method of getting your caffeine fix at the ready.
I want to cover several key areas:
RAW and Jpeg – whats the difference?
An introduction to Adobe Camera RAW (ACR)
Processing your images from RAW to final Jpeg
This should leave you understanding what a RAW file is and what advantages and disadvantages it gives you. The processing tutorial will also be more advanced than my previous article on basic photo processing.
RAW and Jpeg – Whats the difference?
If you have picked up and used a camera before you will have heard of a Jpeg. It’s the file type that the picture is saved as. It is a type of file that can compress an image reducing its file size so it uses less space on your hard drive. It does this by deleting data it thinks is not needed and then mathematically attempts to restore this data when the file is opened. You can also choose the level of compression. You can have a Jpeg that hardly compressed at all as well as one with huge compression. The difference is that a largely compressed file will lose quality. If you looked at a very high quality and a low quality Jpeg side by side there would be a large difference.
