Merging troubles with HDR on Lightroom

[MathieuO]

Hi;

I have updated lightroom.

I am using the merging function to create HDR from several pictures.

Recently, i cannot merge pictures of a set of 7 pictures; i tried using different kind of combinations

(selecting 2pictures for example) but when doing the process LR stops and says i don't have enough similar pictures !

(all the pictures are from the same set); it happens on different sets and on others, it doesn't happen...

"I tried using the HDR pro of photoshop and it is working with no problem"

how to solve that ?

Thanks for any tips

For HDR the images must be framed exactly the same (use a tripod) and be exposed differently in the camera (not adjusted in Lightroom).

You will find some good advice from Rikk Flohr at-
