If you use your camera on fully manual settings (ISO, iris, shutter speed) then exposure compensation is not relevant. If you are using an automatic setting (eg program, aperture value, shutter value) then the suggested exposure by the camera may not appeal to you. Hence you can adjust the camera's 'thought' on what it thinks is the right exposure for your scene. Think of sitting on a bus. You paid your ticket and chose your seat, you've paid for your bag and all is good. It should be a perfect trip. But you decide that the driver is going too fast for your liking - he has a dial on his back that you can turn either way to make him slow down - or go faster! Of course, there may be any number of reasons why the camera's own thoughts on the exposure in hand isn't right. With me, it's usually because a scene is backlit and the subject is too dark. Turning the dial in the '+' direction overexposes what the camera thinks is right, allowing more light in, but in doing so my subject becomes better exposed. Hope this helps :-) -- Cheers, Cotty ___/\__ Broadcast, Corporate, || (O) | Web Video Production ---------- <www.seeingeye.tv> _____________________________ -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
