I don't understand this

I shot a test picture tonight to see what settings i should use tomorrow night for shooting halloween costumes. But when i shot them, i was expecting them to come out pretty good, even though i wasn't using the flash. I was using 400 ISO, and 2 F-stop. It still came out pitch black. I put it into photoshop, and the auto quick fix did its thing, and it came out blue w/ a lot of noise. Am i doing anything wrong?

1. wrong camera settings?
2. not using the flash
3. using PhotoSlop

(Sorry... if you can provide a little more info about your shooting environment and settings it would probably help provide a more useful answer.)

I came onto this by mistake, but your fISO was not high enough, use ISO 800-1600 in dark situations.

G6 doesn't have ISO above 400.

MKNABSTER, what mode were you shooting in? I'm guessing Tv.

Maybe he's in M mode at f2 and has the speed set too fast? If you're in M at ISO400, f/2, and, say, 1/2400, it's gonna be pitch black.

Stay in ISO400, but try Tv mode at 1/60 and see if you can get decent shots, that's theoretically the slowest you can shoot w/o a tripod. If that's not working, try Av mode at f2 and see what speed you're getting, hopefully close enough to 1/60. If you're getting 1" or something, it's just too dark to shoot without flash. Also, note that the autofocus is next to useless in the dark.

Ditch the lensmate and lens adapter and use the flash and ISO 50 or 100, at least for part of the night, it's not like it's hard to take it off... the flash might not be the best, but it's better than losing a night of memories to grainy motion blur.

Bb.

In this case, knowing the EXIF data would really help.

My guess was that he had it in Tv with too fast a shutter speed. The camera couldn't open the aperture wide enough to expose fast enough, so it was dark. Just a guess, tho.

In any case, did you half press the shutter and notice a red reading in the upper left of the LCD?

Nothing could be done there till we could see exif for these shots.
I wonder - what it is "phhotoship quick fix"?

If you're intentionally not using a flash, forget it - it won't work.

F2.0, ss of 1/60 and ISO400 is good for EV of 6 (fredparker.com). I was shooting outside at night with fireworks, candles and some lights on Saturday and you'll be wanting to shoot for about EV2 to EV4, which means using a flash for your G6 (or if you could, using ISO1600-3200, tripod, F1.4 lens). Having said that, it depends on the lighting - I've shot acceptable non-flash photos at ISO100 F2.0 and a little under 1/60 at fairgrounds at night on my G5 held by slightly drunk hand...

The G6, with it's wonderful F2.0 lens, can somewhat properly expose almost any night scene - if you are prepared to wait several seconds. Now that can be a problem with squirmy costumed kids, but with the illumination of a good porch light, you should be able to get the exposure time down to at least in the fractions of seconds.

Well, I had it in Av mode, and I tried M mode, and Tv mode, but i still got all the same results. Do you think i should just keep the flash on, and take the wide angle lense off?

yes, again. : )
