IRIS versus DSS
The same CR2 files, light, darks, bias and flats, stacked in DSS and IRIS.
Object: Westerlund 1
First photo-DSS: size 142 kB
32 bits DSS converted with HDR curves and adjusted level, noise, sharp and curve in Photoshop CS3
Second photo-IRIS: size 137 kB
Some adjustment done in IRIS and others like noise, curve and level in Photoshop. I didn't apply sharp in it.
I didn't see much difference between the results. Work with IRIS is more hard and difficult, because you make step by step all the process. I haven't much experience with IRIS, yet. Maybe other people get better result.
