This article has nothing to do with HDR (High dynamic range = 32 bit per channel or greater) images or creating them. The final image composed is only 8 bit.
Very usefull, especially the last shortcut ctrl+alt+Shift+E
it's a easy way to learn something very interresting
this was real good... thanx m8;)
Some good thinking here, but that's not really HDR. To call it such is misleading. Really just masking 2 different exposures. Shooting a single RAW image is not enough to calculate a response curve, nor create an hdr image. Tho if you have a few different exposures, Photoshop will do a great job of automatically combining them into a useful hdr image. (File-Automate-MakeHDR). After making a true HDR image, you can convert it to 16 or 8 bits, and get a dialog that allows for tone-mapping. This dialog has a great deal of control to compress your dynamic range into a normal photo, but still see the full dynamic range (obviously less global contrast, but local contrast can make up for it). Use the local adaptation method in the dialog's drop-down menu. Play with radius and threshold a bit, but the real power is in the tone-mapping curve underneath. This is really where usefulness of hdr shines in the photoshop world.
Im sorry to say its kinda useless thing........ i guess info is good for the beginners
