Common Kelvin White Balance Settings : 2500K - very strong orange tungsten light 2800K - strong orange tungsten light 3200K - yellowish tungsten light 4500K M6 - flourescent light (most flourescent tubes are green even though our eyes don't see it) 5500K - flash 6500K - daylight (or daylight-balanced flourescent light) 9900K - strong blue stage lighting or evening light
Xenon lighting is rare but that should be between 7000-9000K.
Whenever you enter a new situation that has different WB, just set your Kelvin WB again and test with one shot. You
should be able to do this with practice.
With the Sony A300 and A350, you can use Live View and see the effect of changing Kelvin WB... live!
M = Magenta G = Green 2500K = Blue 9900K = Amber
Take a picture. Supposing the picture is very Green, you need to add the opposite which is Magenta. If the picture is
too Blue you need to go closer to Amber. So if the picture is very blue-green-ish, you will need to go closer to 9900K
M9.
To prevent the built-in flash from appearing in pictures when in wireless flash mode, you can use any of these
methods, or a combination of them:
- use a darker aperture (e.g. F11) - use a lower ISO (e.g. ISO100) - use a shutter speed faster than your flash sync speed so that High Speed Sync is activated (e.g. 1/320th of a
second) - use a piece of exposed, developed negative film in front of your pop-up flash

Before.

Finally got my A550. Mess it around for 30mins, found some bugs with the firmware.
When I switch the AF confirm sound off, it is silent when you focusing (which is correct). Then choose back AF confirm sound to On, it still remains quiet. Restart the camera, remove battery and insert again, doesn't solve this. Only way is to restore firmware. !=.=
Another thing is the LCD brightness.. It suppose to auto adjust the brightness according to ambient. However it does not. Tried to play around with the light sensor beside the LCD, it doesn't make any difference.
If it's firmware bug, then u have to wait for Sony to come up with firmware upgrade.. if ur camera is faulty, then u can send it to repair and claim warranty..
i'll wait till other A550 user for their feedback..
yeap, resize before pp will make u pp in a lower quality.....and diffrent result...correct me if im wrong.. cz i always resize after everythings done ......

i'm already send my a550 for servicing. actually i send 2, one a550 and H1. i already got call from sony about the cost for repairing my H1. but for my a550 not recive any call yet. in the tracking mention " waiting for part". should be FoC since under warranty, i think.

resize is usually my last step. before that would be cropping. before that would be level/contrast adjustment, sharpening, WB tuning, etc

bernama bro, kenapa hantar service your a550? kan baru je beli? ada problem?
I usually PP after crop / resize. Because when resizing, image quality will degrade. So special touches need to make the picture better. Last step would be unsharpening the photos. Thats my workflow.
Hinika: If I know I am only going to use it at a low resolution then I post-process after resizing; makes editing a lot, lot faster.
littleway: If you are in AF-C there is no sound and no AF assist light.
porkchop: You can't see anything from the IR filter-ed light. However an IR-sensitive camera, can.
CCTVs have IR lights and often work in IR only. So it turns on the light when there is none, as humans cannot see IR. Quite like the Sony Handycam NightShot mode.
ieR: Please state your source!
signither: You could try my Kingston 133x 32GB card in your A700... no reason for it not to work. My card doesn't work in an A100 though.
bernama7: Wah do you live in the forest?
neo_lam: Just get the dry box. I have that exact same thing and it is tedious to keep charging it every few days.
Keeping a lens in a bag is bad. Bags will promote fungus. Left my beercan in the old A100 bag and that's how it got fungus, and I knew from then on I had to get a dry box.
davidmak: It is well known that the A550 does 7 FPS with AF and AE off. And yes 5 FPS is with AF and AE.

Ahhhhh! New a550 users who got the package from Sony Style! Sell me the Sony MS10 bag la. Get a crumpler or lowepro or something la! So desperate for that MS10 la but dont think paying 250 for that bag is wise. ):
