HDR images not matching

[Helmut Harringer]

Good day, I used my bracketed images to create HDR, exported them as 'blend planes'.

But they don't match, there are sometimes immense differences between the two images.

What I'm doing wrong?

Thank you!

Hi Helmut,

Do you mean differences in brightness? That is to be expected, each blend plane is taken at a different exposure. You are expected to merge them externally.

Kind regards,

Are the differences positional? If yes, did you shoot from a sturdy
tripod? You might have tipped it during shooting. Or if you shot hand
held, they are not supposed to fit.

In these cases you can try to align them. See https://ptgui.com/faq#7_8
for details.
