Hello,
I had previously sent a noise profile for Sony SLT A57. However it appears
that I did it wrong (I applied the raw linear style and exported to TIF
instead of directly using the script on the raw files) and the results were
so-so.
So I did it again correctly this time and averaged 4 results, resulting in
the file enclosed. The benchmark gives much better results now:
iso SNR SNR(denoised)
100 33.4287 39.1862
100 33.1003 37.7645
100 33.5202 37.0549
200 31.3615 34.7328
400 28.7384 31.0138
800 26.5365 28.8948
1600 25.3618 29.1122
3200 22.6094 26.8069
6400 20.3917 23.6378
12800 17.4555 20.7442
16000 16.2223 19.2449
Please push this corrected version.
Thank you!
Baptiste
