It's not "RAW", it's just "raw"

At the end of this old post by John Nack at Adobe I found corroboration of my feeling that putting “RAW” (as in, raw image files from digital cameras) in all caps is silly. Some might feel this is a level of detail that only concerns copy editors and trademark lawyers, but I’m like that sometimes. I’ve always preferred the nice, simple “raw” as the term for this sort of format.

Photoshop CS3 beta

Update: It’s out. Download here. Also see’s review of new features. In case you haven’t heard, Adobe’s releasing the beta of Photoshop CS3 in a few hours. It will be interesting to see how much of the Lightroom-style interface experimentation, if any, has made it in there. This is especially big news for Intel Mac users, who have been stuck with Rosetta emulation for Photoshop. Note that the other Creative Suite apps – remember them?

Software for determining image similarity?

This is a lazyweb request – I’m looking for something but I don’t even know if it exists. I have about 200 photos (headshots) and I’d like to make an animation that runs through them in order of, for lack of a better term, visual similarity. I’m not talking about morphing or just fading between the images in arbitrary order. Is there software out there that, given a reference image and a set of images to select from, can choose the most similar image?


Today Apple announced their new imaging application, Aperture. This is clearly intended to be a high-end app, and Apple wants to make sure you get that. “Aperture: Designed for Professional Photographers.” A retail price of $499 ($249 educational). A website that reads: “Whether you’re a fashion, wedding, sports, portrait, fine art, commercial, or editorial photographer…” And the recommended minimum hardware: dual 2GHz G5 PowerMac with 2GB of RAM. It’s more of an image processing application than an image editing application – pixel-level editing tools are scarce in Aperture.
