So I'm trying hard to understand what the big deal is with RAW and why I should be using it more often.
There's got to be something else!
I must be missing something here.
And if you end up saving the end results of your editing as a JPG anyway, for printing or publishing, then what exactly are you gaining by having a RAW file photo?
Wouldn't this end up crushing your beautifully evolving Sky colour into several JPG steps?
Unless the end result is a TIFF, but I hear they're incredibly big files, so are rarely used.
So, clearly, there's something I don't understand here, in relation to RAW files.
Which isn't really a Photo Editor discussion, but is kind of related, I feel.
Maybe there's a stock type of photo I can take to highlight RAW's higher potential inside an editing program.
Maybe some RAW editing programs offer more / better RAW processing than others.
Unless Developer Studio 3.0's "Standard" Contrast is as good as it gets...
(I'll create a New Thread on this subject as well, to highlight the subject)
The RAW data is just that it's ALL the data the sensor recorded and that is much more than any single file can resolve.
Lets take a common problem, an interior in a darkish room with a window that has bright daylight. If you convert the file to a Jpeg it will try to encompass all the dynamic range in the file .
Dynamic range is the number of f stops in the brighter pixels before they just reproduce as white, there is no detail data in these pixels.
Likewise the darker pixels go readily to black, again no data to give detail in these parts of the image.
But this data is still available in the image file and by selecting say the bright sky and turning down the exposure you will get the sky detail back. What we've done is to reign in the bright pixels so that your output device (monitor or printer that have limited dynamic range) to be able to re-produce those pixels, the same applies to the darker parts of the image too by selecting and then increasing exposure in these pixels.
The same happens with colour balance too. The sRGB used in Jpeg files just cannot reproduce any bright red or blue. Jpeg is reasonable in reproducing the colours in nature, only poppies can't be reproduced correctly and are usually a red blob of tertiary pixels, any man-made bright dyes say in anoraks can't reproduce correctly either.
There are programs that can draw the data from a RAW file and bring any pixel within the range of any output device, I use Photomatix Pro which you can try for free (it puts a watermark on the output, but offers all the tools) and you can see just how much data can be retrieved from a single RAW file. If your camera can bracket shots Photomatix will use ALL the data from multiple RAW files taken with different exposures. I take just 3 images 2 stops apart. Pentax are great at taking bracketed shots just use the drive button to select on the fly, very quick.
Once you save as Jpeg all this extra data is just dumped which is why the files are smaller, High Dynamic Range black and white images can be really stunning with high levels of detail throughout the image.
