Hi all,
I've been testing my P21 under the last days. I thought maybe some of you could be interested in the results.
I'll probably be doing a big project that will last a few years (beside assignments), a research project the will be planned around music and photography put together. This could imply very big prints. There comes the question of my 18 mpx being capable of producing that king of prints. We are talking maybe 1 meter high.
So I put a simple scenario were I'll put my H2 and P21 to hard test. I want to see sharpness and DR in the first place, and I want to know how much the files could be upsized without loosing (too much) quality.
Can I get comparable quality from a resized P21 file beside a P30 or P45 file?
The motive of this thread is to find out how resizable medium format files are. I'm not very familiar with resizing but I know a 18 mpx DB can stretch a lot. But of course, there must be a limit. I'd like to get, if possible, real information here, not too much charts or thesis if you know what I mean. Anyway, any medium format user will recognize the sharpness and detail rendition of these captures. For 35mm new users here I suppose this is a kind of eye-training about what a DB can do.
So I'll start posting the full picture version with 100% crops of the file. And then, after your advice, I'll resize the picture to see where I can go.
Details:
- Camera Hasselblad h2 and PhaseOne P21
- Lens: Hasselblad 210mm HC
- No flash used.
- ISO 100 1/2s at f7.1 on tripod and mirror LU
- Processed 16 bit tiff file in C1 with everything to 0 (sharpening or noise reduction)
- No adjustments of any kind, the file is totally flat.
- Then imported in PS and made a print. Added sharpening amount 35 ratio 1 ( just what I thought the print needed).
So there's minimal processing, almost flat.
My initial observation is that the 210mm is scary sharp actually. Very good and natural color rendition. The picture got a little warm after the web conversion but color isn't my main concern at this point. Also the combination is capable of resolving a lot of detail. Some of the crops are amazing, like the texture in the card or the small clock's knob.
The the jpg versions also loose quality againt the 16 bit tiffs but...
