RAW questions

[Logzor]

I just started shooting in RAW with some good results. I notice that after I have done the photoshop work the file size is much smaller than a noram jpeg. Why is this?

Also, sometimes my edits that I have made in the RAW editor do not appear the same as when I save it out as a jpeg. Why is this?

I am running photoshop CS2 with RAW 3.2 (or something like that). Can I use a better version of RAW editor?

Thanks for any information.

hmm sounds strange- the only way your file size would be any smaller than the original is if you saved it as a lesser quality image or changed the actual image size. Double check how you are saving the image after processing it - either save as a .psd, .tiff or a .jpeg (the .jpeg is compressed typically) and the other two will leave your file more a less in tact.

because the jpeg is compressed, you will lose some of the information that the original file contained- resulting in the slightly different (usually worse) appearance. however, major changes that you make in raw should still be evident on the jpeg.

I like to save my raw changes as a .psd or .tiff before i downsize the image for the web (and save as a jpeg) so that I can come back to the original raw adjustments and the original pixels.

im not sure if a better version of RAW would do much for you..

good luck!

Perhaps changing your raw editor to sRGB instead of Adobe RGB would do the trick?

I agree with both of the above. Look into your color space especially, as its an issue you likely didn't even consider.

I don't think that would work, and would likely decrease quality. I could be wrong here, (but I don;t think I am) that sRGB is a color space designed for use on the web. Adobe RGB has a much wider color gamet that what the web is capable of displaying. Thus the color gradations (and potentially the amount of information in the files itself) are probably larger in the Adobe RGB color space than the sRGB. There really is no reason to use sRGB unless it is speciifally for web use. The probability of banding and more harsh color transitions are increased with sRGB (to the best of my knowledge).
