Hi all With regards to my Canon Speedlite, I would like to ask the following questions: What are effective techniques to minimize shadows being cast against a wall behind your subject, when using the flash? And then also, I noticed that I get much better results when I use the "manual zoom" to cover the range of the flash, as opposed to leave it on auto (with manual zoom, the value used is equal to the focal length of the shot). Any reason why? Sometimes it is difficult to adjust the value manually when taking a lot of shots in succession. Another issue I have noticed, which I suppose could be related to the second question, is that when the zoom of the flash is on auto, my subject is much more illuminated at the telephoto end of the lens, as opposed to wide angle shots. But my distance from the subject is the same, so I don't understand why? Especially because the value in metres of the coverage of the flash is higher (with other words, stronger flash?) with wide angle shots. Comments would be appreciated!
