Flash creates shadow when camera is vertical When I flip my Digital Rebel vertically for a portrait shot, there is a faded shadow that works its way diagonally from upper left to lower right corner of the image. So the darkest spot is in the lower right corner of the image. The fade doesnt really start until about 60% down the image so the head, neck and sholder areas of my subject all look fine at just about any zoom level which is a relief. I'm assuming the built-in flash is just not that great (I'm working well within range at 10 feet), and it just cannot light very evenly. Also, the uneven lighting isnt horrible or anything, but I do notice it especially in that lower right corner of the image. Could someone let me know if this is a problem with the flash being moved to the side of the camera because I have to flip it vertically for portraits? Or does this happen because the flash built into the unit is too cheap for decent portraits? Or is this a deffective camera? Any other thoughts?

>>Or does this happen because the flash built into the unit is too cheap for decent portraits?<< Sort of, or one could say the user is too cheap to buy a decent flash/lighting set-up for portraits. ;-) (joke) What lens focal length are you using? The built-in flash's coverage is spec'd for 18mm focal length and longer. If you are using 18mm (possibly shorter than marked on the lens) or shorter, then you'll see light fall-off at the edges of the frame. In that case, or if the low-mounted built-in flash is casting a shadow from the lens, it should also show in horizontal orientation as well (same corner, rotated).

P.S. The light from the built-in flash is emanating from a very tiny source. More even lighting requires large sources (large softboxes, lights reflected into umbrellas, etc.).

It probably also happens when the camera isnt flipped on its side. I'll have to experiment with the camera to check that. Most of my photos are landscapes. I'm using the lens that comes with the canon digital rebel, and also a longer zoom lens in some situations. I think youre right that its the built-in flash. Given that, I'm planning on purchasing the Canon 420EX Speedlite (Guide No. 138'/42 m at 105mm). The reasons I've decided on the 420EX Speedlight are really just features/cost. Thought I was getting the best bang for the buck and dont want to go over $200.00. Any suggestions on a better flash in this price range?
