I thank God not immediately purchased the program, but only tested. Actually, the program would be great if the crashes were not that prevailed with me after a few etwickelten images. Whenever I (Nikon RAW) have reopened in Develop mode a particular already developed .NEF, came the message that the program be closed because of an error must - until then occurred directly after the start. The tips on the homepage have brought nothing with me. Since I obviously am not the only one in which the problem occurs, and it seems to be not only in the version 6 so, here more than one star is almost too much. Hopefully the developers in the future more effort! Another bug (in the image editing, for example, with the effect of "stone"), however, is almost meaningless, so I did not continue up out him. I'm afraid I must therefore give as many as LR preference, even though since the image processing (effects that go beyond Vigettierung) is missing, and it is more expensive and more resource eats and I do that with the import dislike in LR. The RAW development is me (have since, however little experience yet) comparable - only the radially extending filter from LR 5 (I test currently) would my ACDSee 6 something missing now that I know him.
