Just posting an observation that had not really occurred to me until recently. I just purchased a Custom Bracket for my 1Ds which mounts the flash above the camera and allows the camera to rotate easily between landscape and portrait orientation. However, when the camera is in the portrait position and the flash of course is still in it's normal orientation, there are two dark bands in the upper and lower half of the photo. The landscape rectangular shape of the flash no longer matches the portrait shape of the camera image. The problem is worse at wider angles, but always a problem. I can put my Lumiquest Bounce on the flash and pretty much solve the problem, I just wish I did not *have* to. The thing is big, cheesy looking, and in the way. Anyway, the whole point is, why can't flash heads be made in a more rounded shape with some real diffusion built in? Why should we have to pay hundreds for a high end flash and then have to buy all kinds of do-dads and gimmicks to diffuse the light and correct orientation problems like I have encountered? Seems counterproductive to me. Any opinions? Steve www.parrottimaging.com *********************************************************** It's because on-cameral flashes have to maximize capability with limited power. What does that mean? In order to achieve proper lighting with a given lens, they focus their light for that lens pattern, ie, they are designed to project enough focused/directed light for the scene when mounted in the hot shoe. They don't have enough power to light outside of their focused area. When you use them in non-standard orientation (ie mounted sideways on your fixed flash bracket) the focused light may not cover all the area of your field of view. They are designed this way to maximize their lighting capability with limited power. To expect much more with 4 batteries is to not understand their limited capabilities. Using a diffuser will help cover outside the designed parameters, but it will limit the range. The limiting factor is how much light can be produced by a battery powered flash. Try using a omni-directional flash attachment and limiting your range or increasing your ISO setting. Alternatively, you can use off camera/remote controlled flashes to set up lighting closer to all the areas you want illuminated. Photography by definition means to record images with light. You have to chose and set up the proper lighting. One on camera light is often not enough. * **** ******* *********************************************************** * For list instructions, including unsubscribe, see: * http://www.a1.nl/phomepag/markerink/eos_list.htm ***********************************************************
