comment How to get high contrast texture?
In Photoshop: copy the layer to a new one above, apply a high pass filter, and then select "Overlay" from the blends rollout, adjust "opacity" of that layer as desired.

comment Why do my tiff files balloon in size when saved with 1 adjustment layer?
TIFF is really just a data wrapper and whats inside can be of many different formats. Its really hard to tell what is being saved exactly, or for that matter to control what is inside it. Photoshop may reuse the curve data when its reloaded, but other apps might not. If your intention is for it to go to another app, you might just want to collapse the curve data by rerasterizing the image first. What app is your intended target and does it even understand the additional curve info as Photoshop saves it?

comment What sort of damage in a camera can cause these photos?
I don't think youve ruled out the CF card. Whats showing on the camera lcd likely comes from whats stored on the card. I know if I dont have a card in I can't take a picture at all. That tells me theres no buffering in the camera.

comment Is GPU or CPU more important for Photoshop and Lightroom?
emphasis on the disk speed. of course capacity is important, but a fast hard drive will positively impact the performance of adobe products. first hand experience. In fact, I have not seen any single program benefit more from a fast hard drive than Adobe Photoshop.
