Av TAv Question

Took my new K3 out for the first time today. I shot using the Av mode and he Av TAv mode. When in the last a number of pictures all had the same exposure. Same ISO, shutter speed and aperture. The pictures came out terrible. What did I do wrong?

I used the Av mode and changed the aperture as needed. They came out great. By the way, the ISO was the same for all of them. I thought it floated up and down.

Appreciate some hints please.

Can you post some of the samples that turned out terrible? TAv is where you set the shutter speed and aperture manually and the camera picks the ISO, and it's not always going to be possible for the camera to expose the image properly even at max iso if there isn't enough light.

On the K-7 to have the iso run in auto you have to set the auto range and then hold the green button and press the iso button to switch it to Auto mode for TAv.
Check the K-3 manual to see if this is the same/similar.

The iso shouldve floated. However if you had the aperture set numerically low and the shutter speed low.... the pics would be overexposed and blurry. If you did the opposite side hey might come out dark. Depends on the limits you set and what the camera is capaplble of.

Alternatively you could've had exposure compensation on.

Tav allows you to set the aperture and shutter speed and the camera will set the ISO, within the ISO range selected. So if you have the ISO range set to 100 to 800 for example and the camera needs 1600, things don't come out right. It will just go up to 800 and then the exposure is wrong. At least it works that way on the k-5, have not tested it on k-3 yet.
