hi , am new to this got some questions to ask re FLASH
hope you guys can help!
1. when checking focusing issues for lens, eg front/back focusing. Is it detrimental to use flash? even with relatively slow shutter speeds, flash tends to freeze the image and will allow a sharper image.. why then do most pple turn off flash when testing lenses in a dimly lit area? eg shop area
2. when shooting flowers, i find that using flash even in daylight produces very vibrant colours. why do pple avoid using flash for such objects then?
thank you
