Those who are not familiar with the website DPReview.com can’t claim to be seriously interested in photography.

Once again, I was out taking pictures with the Quattro – this time in very soft and flat light. On the whole, I am happy with the results. Slowly, it dawns on me how exactly I need to edit pictures taken under a cloudy sky. For me, the difficulty so far was to correctly adjust ...

After several forum entries regarding the narrow dynamic range of the Quattro, especially the small reserves in the highlights, I started my own comparison with the DP2 Merrill to literally see for myself.
