Expose to the Right Revisited
Once upon a time there was an esoteric technique for reducing noise at high ISO called "Expose to the Right". It worked like this: You overexpose the image by about a stop or so (but not so much that you'll blow out the highlights!), and then bring the exposure back down in Photoshop. This technique reduced the noise by about 1-2 stops' worth, which was pretty good. Since those days, modern camera manufacturers have changed the way brightness values are represented in RAW files for efficiency, and some have claimed that this makes the ETTR technique less effective.
Is this true? I decided to find out.
