You need to control the lighting. You can do this with shades, reflectors and for glint you try the usual polarizing filter. I've yet to see cameras that can beat back bad scene lighting.
Have a Samsung HMX-H200N. On contrasty shots I get glare, light seeping into dark areas turning them grey. Two modes stop this 'candle' and 'spotlight'.
Why do these modes reduce glare please? Is there a tweak I can do on the basic mode to reduce contrast glare?
I was also wondering if HD videoing is more prone to this effect than SD because I noticed it on the tv this evening as well - maybe it's not just me?
