I have tried taking a 9 bracket shot at different exposures and merged the DNG files in Photomatix to get an HDR. The HDRs seem very noisy compared to the DFE(R) HDR.DNG. Also merging the .JPG of multibracket mode seems to have lesser noise compared to merging the .DNG’s.
Thus my questions are
a. Im assuming the only additional function the DFE(R) is performing is merging the DNG’s. Why does it have lesser noise ? Am i doing something wrong ? will a better software to merge DNG give me a better result ?
b. If DNG’s carry more data, then why does merging multiple JPG, give a better result ? Again am I doing something wrong ?
