Problem with HDR

Sorry if this is an FAQ but I couldn't find much information on this forum or in the docs.
I have a number of bracketed exposures with EV -1, 0 and +1. The preview looks ok, but when I select HDR color correction and then open Tone Mapping RH4 dialog and select Enabled, the preview becomes just a black rectangle - is it normal? If I select LDR color correction, it renders ok but highlights become overexposed.

Thank you!

JD.

Re: Problem with HDR

You have to adjust the Tone Mapper sliders to get the correct exposure...

Nope, it doesn't work. If I move both sliders all the way to the left, I see some details but the image is still very dark.

Did you use anchors?

I think you'll be a lot happier with overall results if you tone map first with Photomatix Pro. Then stitch with APP.

Re: Problem with HDR

I Agree, there is a bug... I can make it work when the color correction is on none instead of HDR... But the filter are not convenient to use anyway. I really love Autopano... But for HDR, PTGui is better... Let's cross finger that next version will have better HDR function

I agree, PTGUi does a better job with HDR than APP. However, overall, APP is without comparison. But for HDR, nothing better than Photomatix Pro.

Re: Problem with HDR

Don't confuse HDR with tonemapping.

APP-2 is planned to have better tonemapping and exposure fusion.
