Ira Block called this weekend to report on a sharpness issue with the Canon EOS 5D Mark II . He and his assistant were comparing files shot on the 5D MK2 and the Canon EOS 1Ds Mark III , the MK 3 files appeared sharper viewed in photoshop. To quote his email:
Well we did some testing and it seems to be an adobe issue. The 5d Mk2 files
look sharper when using DPP or capture one . But somehow the algorithm in
adobe (photoshop) doesn't cut it.
I did think that adobe got the raw update to photoshop cs4 out very quickly. I guess too quickly.Thanks Ira, I just wish you had told me before I upgraded photoshop...
In a follow up email Ira says that the difference is most noticeable in low contrast images. Neutral Day has some higher contrast conversions here.
