P45+ first impressions
« on: April 18, 2007, 06:00:54 pm »

got my P45+ today, (contax 645 fit) and a few quick notes:

Screen - a real improvement brightness and resolution all up, notably easier to ready type and information. higher res means better clearer type, which is great.

Histogram - now very easy to read with clear R,G,B lines overlay, plus ASA, f stop and speed info right under. very easy to interpret. big improvement and should make for more accurate exposing on location. great.

Output - a definite improvement on my very quick tests. Not a stop like they claim, but for sure less noise at all ISO's. everyone in a blind test would take a + file over the old one at 100asa and above. (takes a more experienced eye to see it at 50asa, though it is there).

all ASA - seems to be about 1/5 to 1/6 more sensitive than non+ back

50asa   - an improvement in shadow noise, marginal in mid and high tones
100asa - clear improvement, much less noise. usable as everyday standard now
200asa - substantially improved now an option for acceptable quality work
400asa - big improvement, usable if you really need it (wasnt before)
800asa - for emergencies only...

sharpness. no idea what they have done, but I'm showing slightly better resolution in each test shot on the + than the regular back.  why ??

The + back comes with Capture One 3.77, which installed fine - no issues (windows)
this has the + profiles, which seem pretty good, and hopefully will improve as things bed in.

small grumble: they still haven't managed to put a 5cent plastic plug on the Firewire connector like they promised... ack!

Any possibility of posting some sample files?  (I'd be happy to host the files if you are concerned about webspace or transfer bandwidth).

Many thanks for sharing your first experiences.

Best regards,
Brad

Brad,

Please take a look at our Capture Integration blog.   We have some sample images from the
P30+ and the P45+.  We also have posted ship dates for the P+ backs.

Thanks for posting this; that P30+ ISO 800 file is much cleaner than my current P30 at that ISO.

Hi, Chris.

Your blog has a lot of great information in addition to the sample file--thank you!

Out of curiosity, what camera and lens did you take the P45+ picture with?

Best regards,
-Brad

Brad,

You are welcome!

Chris, did you use iso 50 on the P45+ file?  If so, how do the higher iso's compare to 50?  How does the 45+ noise, or lack of, compare to the 30+?  Thanks, Eleanor

Eleanor,

We did shoot the P45+ at 50 ISO.  sep39 sums it up pretty well.  There have been some great improvements with the new P+s and they will be even more to come.  Phase One had promised us better results with the new C1 4.0.

Chris,
The P45+ image looks good, did you apply lens cast correction to it?
I would love to see 400ISO sample from the 45plus too
thanks

thanks for posting! just looked at the P30+.....maybe it is the jpeg, but there does not seem to be less noise then with my P30, but maybe less COLOR noise?
the P45+ jpeg looks great.....of course this is as always hard to tell from jpeg, but nice lens! i wish i could get a better feel of phase's claims of better DR.....

i wonder how much of the + advantages will really start to come out with C1 4.0.....

just looked at the  P45+ sample and (although this is jpeg and we don't know much about it) i was surprised by how crisp the file is....crisp without a trace of sharpening (especially for a jpeg!)...of course the lens it great as well, but still.....

do you see any improvements in DR? do you see the "extra resolution/sharpness" across the whole iso range?

David,

There was a LCC applied to the P45+ image.  I'll try to get a 400 ISO posted to our blog.

You mentioned you installed Capture 3.77. My guess is that they've tweaked something in the software - maybe refined the demosaicing algorithm, or reduced the default noise reduction due to lower noise characteristics of the + backs. Just a guess, tho.

I know we've gone around on this before, but either I'm hyper-critical about noise, or I have a very noisy P30, or you have the least noisy P30 in the world.     That P30+ ISO 800 shot is way better than my P30 at the same ISO.  There's both less noise (in terms of the total amount) and less color noise (the noise that is there in the P30+ shot has a lot less RGB "speckly" noise than my P30).

this is impossible to tell from jpeg....not knowing how these are processed (is there a way to NOT use any noise supression in any software?)....it definitely looks like less color noise to me....i will do a test for myself when i can get me hands on a P30+......

what i am looking for in the + series is less color noise in the shadows....and since phase says less noise, better color and higher DR, i might just get what i am looking for.....

the real "problem" is that the P30 is pretty amazing as it is.... so if the + step is not THAT great, i might not pay for this upgrade but wait for the next....

i will do some testing when i get the chance...

Dear William,

As I wait for the P45+ I am also considering the P30+. For a strange reason; I have glass that will fill the 30 but not 45 frame, and yes, I could use the extra sensitivity. Is the 800 on the 30+ generally useful? by that I mean, using more for higher speed for wildlife (rather than dim light)

regards
