hdr issues

[d1star]

I have been exporting the same pic from lightroom at -1, 0 and +1 exp as oppossed to bracketing 3 sepperate pics. I use dynamic hdr and I seem to be losing some image quality especially on ultra contrast setting will I get better results bracketing my photos

In a word - yes. Altering the exposure to produce -1 and +1 images isnt the same as bracketing in camera. You are stretching or compressing the data when you are manipulating the image to get your -1/+1 - but obviously you arent creating any new data. Bracketing will allow areas that were blown out in the original exposure to include data in the -1, and clipped black areas will now have data in the +1. But exporting as you have been doing is better than trying to make a single exposure with a large dynamic range work on its own!
