K3 in TaV mode won't shoot at ISO100

**frogoutofwater** · 01-30-2016, 10:14 PM

All of a sudden, my K3 has stopped shooting at ISO 100 when I'm in TaV mode. I have the Auto ISO range set to 100-4000, but it won't shoot at 100 anymore, and as a result a bunch of my images are ending up over-exposed. Anyone had this problem before?

If it stops at ISO 200 check shadow & highlight corrections. If I remember right that restricts ISO to 200 and above...........

That was the problem. Thanks for the quick reply.

I love the Pentax Forum - toss a question out there in the middle of the night and I get a helpful response almost immediately. Here is a photo of Lillian, a 3-week-old rescued goat as a thank you.

Well, it's the first time I have been given a goat as a thank you

We used to have pygmy goats back on the farm a long time ago. This one smells much better

You should be able to use shadow corrections, just not highlight corrections, FYI.

That's because highlight corrections work by underexposing (i.e. pretending ISO 100 is actually ISO 200) and then lifting shadows.
