Hi Gidon and Gareth,
Is there anywhere on the web that explains all this RAW stuff in easy to understand language. I've done conventional, black & white, film-based photography and processing for years and have no difficulty with it, but all this digital stuff is a black art to me :? :? :lol:
Cheers :wink:

Hi Paul
In addition to Tonys excellent links is this one:

And specifically the RAW definition which is pretty similar to Tonys description.

Using RAW is a learning process as you need to develop a sequence of actions often called a workflow. This is my workflow:
1/ Take pictures using RAW setting on the camera. Mine can only do RAW only or jpeg only, modern cameras can do both but clearly this takes up more space on the card. RAW can be stored uncompressed or lossless compressed. I use lossless compressed as it is no different IMO to uncompressed.
2/ Import the pictures from the card/camera onto your PC or MAC, review and delete the horrors
3/ You then need some software to process the RAW files. I use a simpler version of a Pro program called Capture One by Phase One which can be downloaded and trialled here
http://www.phaseone.com/4/ . Adobe Photoshop can be used for RAW processing and all the major camera manufacturers can supply RAW processing software
4/ Set white balance, automatic, preset settings for Flash, Cloudy, Bright sunlight etc etc. or manually set the whitebalance and customise to taste
5/ Crop picture. Unless you have every lens ever made and perfect framing technique. This is where you can isolate the best section of the picture and zoom in or just cut out unwanted edge detail. With high res cameras such as 10Mp you can crop quite severely without losing resolution too much. With my low res camera I need to be careful as I don't too many pixels (2.7mp)
6/ Select exposure settings, again auto presets or manual fiddling with saturation, contrast, hue, balance, plus or minus exposure. This is the most fun bit to me and along with the white balance you can rescue many a poor exposure
7/ Repeat for all pictures
8/ Set up a batch and process all the above
There are shortcuts and if you shoot well initially there should not be too much custom processing and you can get through your pics quite quickly. You tend to concentrate on the good pics and put your effort into these. For holiday snaps I just put the lot in a simple Batch and use auto settings rather like the camera would do.
Here is a workflow from someone who knows what he is doing
