Default In door shooting

I was at 2011 CES taking pictures. I was using the A900 with SAL70400G 70-400mm f/4-5.6 Zoom Lens and SAL2470 f/2.8 in A mode. I find myself having a hard time taking nice pictures because of the lighting inside the Convention.

was it ok to use A mode or i should of use the P mode.

Thanks all for your time....

P.S..still learning how to take great pictues.

Can you post some examples of the shots you're less than pleased with?

Either should be just as useful.

I agree with Mike - balancing the light with the aperture or shutter is key. Much depends on the situation. Is shutter speed the priority or depth of field?

Clint..shutter speed was priority...

There's no EXIF data available, so it's hard to get specific. All your subjects are wearing dark clothes, and in the first and second, the background and foreground were very dark. In the first, the lighting was bad. But I think the third, fourth and fifth are reaonably good, considering everything you were dealing with.

The first one was the toughest with all the dark background. You might try spot metering to get the exposure you like then click. Metering on the darker areas would bring them out but you have to be careful not to meter on too dark of an area or the bright areas will get overexposed. A good flash would also help fill in the dark areas.

I think some turned out well, except for some motion blur.

Like others have mentioned, we can't see the EXIF information for the images, so we can't tell what camera settings were used.

But, as as general rule of thumb, you'll need relatively high ISO speeds with a wider aperture (lower f/stop number) to get many blur free shots without a flash in typical indoor lighting (and a lens like your 70-400mm is not a great choice, as you'd typically want to be shooting at f/2.8 or wider apertures if you can't use a flash in most indoors lighting to minimize blur from subject movement).

Timing the shots for when the subjects are motionless can help (as in some of your shots, except for a bit of hand blur).

Any choice tends to have tradeoffs (for example, more noise with higher ISO speeds versus more blur with lower ISO speeds).

I'd shoot raw for more flexibility in post processing.

Thanks everyone.

Today, I used a A560 with a SAL2875f/2.8 lens, in A mode with ISO on either AUTO or 1600. Was very difficult to get a good picture.

While I think some of them are quite nice, most of them suffer from very significant differences in lighting within the scene. As good as the A560 and the Sony/Tamron 28-75/2.8 are, they can't make light where there isn't any.

Also, the Sweep Panorama Needs to use a relatively fast shutter speed so as to not blur the scene as you pan. If you're getting shutter speeds of 1/10 and 1/15 when capturing conventional images, panoramic images will be underexposed. That's what happened when you tried it.
