Photo Forum / Digital Photography / DSLR Cameras / February 2006RAW - File Size Changes when Saved as .psd
My thanks to all who responded to my post regarding RAW + Jpeg. I downloaded the extractor and I am very pleased with the ability to make adjustments using the PSE3 Plug-in. I have the zeal of the convert and will now shoot only RAW with my beloved D70s. I notice that when I save the .nef file in the .psd format, the size triples (i.e., the original .nef = 5200kb; the .psd = 17,000 kb). Is this normal and can anyone explain why this happens?

After conversion, the file has three color channels instead of one. The PSD will get even larger if you use layers, and then Photoshop may even add a preview to the file, making it larger still. It's all normal.  SignatureJeremy | jeremy@exit109.com >My thanks to all who responded to my post regarding RAW + Jpeg.

In fact this tells me you have only 8-bit data, which you really don't want to do at this stage. In the raw converter pane look at the lower left hand corner and you'll see a pull down menu for bit depth. You really want 16 bits at this point. When you save this you'll then see this is approximately now twice as large as before. Remember psd supports much more things, especially layers.

If you're outputting the final product, 8-bit can't really be bettered in any practical way.
