clivengu: The toilet bowl diffuser is universal as it comes with a strap to tighten around the flash head.
Also, the Stofen for the Canon 580EX II is the same size as the F58.
Seng_Kiat: The A700 screen is a bit warm when viewed straight on, but accurate when viewed at a slight angle.
Yes, orange gel for tungsten, green gel for flourescent.
Aiyaaa no wonder lah. If you use flouro WB (4500K M6) with neutral 5500K flash you get a blue-ish, magenta-ish flash!
ALL of
http://img.photobucket.com/albums/v141/afham07/DSC00957.jpg is lit by the flash, and none by the flourescent light because you have
underexposed your ambient light. (F8 1/30s ISO200). If you went the other way, say F2.8 1/30s ISO1600, you will get more flourescent light (and you'd get a more neutral white.) So your flash should've used a green gel.
Also, remember that flourescent light
flickers according to your house AC (Alternating Current, 50 Hz) so you'll want to use a slower shutter speed if you are shooting without flash.
Try shooting 10 frames at 5FPS F2.8 ISO1600 1/1000s while aiming at a flourescent tube (at night) - you'll see how it varies. Either you totally kill ambient light by shooting F8 1/30s ISO200, or you maximize ambient light at F2.8 1/30s ISO1600 (depending on how bright your flouros are lah.) However it is obvious due to the flicker, that is why studios do not use flourescent tubes!
* Flourescent tubes come in different color temperatures. They are not always 4500K M6. Some are daylight-balanced flourescents (great!) and some are tungsten-balanced flourescents (2800K or 2800K M3). Some mamaks mix flourescent and tungsten light so I pick 2800K M6 for that.
millenia3000: Nice bokeh on the handle!
Great info on the fluorescent lighting...
Does the A900 screen have the same issue with A700? Havent checked on this yet...
