Jaapv, take it easy. It is my opinion that his shot would have had allot of blooming if it had been shot digitally. That the area around the window frame especially the wood framing that separates the panes would have been totally lost. He was shooting in interior light with windows showing an exterior view.
The well captured example you showed was captured outside and pointed into the setting sun. I think that they were two very different types images. And can not be compared for illustrative purposes.
I'll just say that I do not believe digital has the same dynamic range as film in the original example that was displayed.
😛 I anticipated this answer, so I shot ( digitally again) a scene with about the same exposure that Vince had, straight out of camera and Jpeg, just resized and sharpened for the web. Note that not only there is no blooming whatever, not even on the brass doorknob, which is a notorious situation for blooming,but the sensor handles the contrast excellently , even if I exposed the shot for the shadows and totally blew out the windows, which is the wrong way to go about it in digital. To compare I shot a "compromise"exposure, mostly for the highlights,, which shows that the dynamic range is at least as good as film, and certainly better than the final medium, be it print or monitor. And again no blooming.
🙂 Had I not been lazy
🙄 and shot this one in RAW I would have gained another stop or more in the highlights,and been able to balance the exposure in the conversion and post-processing for 100%. That that would have spoilt the atmosphere is another thing.
Sensor blooming is more a fault of the Cmos sensors, as used by Canon. CCD sensors, like Leica/Kodak use seem to be far more stable. This leads me to suspect that it is less the neighbouring pixels being influenced by burnt-out ones, but flare in the AA filter. I am sure there will be no problem in the Digital M.
For film-shooters on this thread: Sensor blooming occurs in very high contrast situations, like for instance bright highlights on polished metal and shows up as pink or purple fringing around these highlights. The theory is that blown-out i.e. grossly overexposed pixels excite the neighbouring pixels. I have never seen proof of this theory, but maybe some electronics expert could comment on this. At any rate, the solution is simple: don't blow out the highlights, just like slide-film. And if it happens, it is usually acceptable, because the eye accepts some flare or similar around extreme highlights on the print, even thinks of it as "sparkle". Some types of sensor are more affected than others and it also depends to some extent on the lens used.
P.S. If my prevoius post read irritated
😡 , this was not the case, I was just in a tearing hurry....
