    I had to climb a 20' dirt pile to get this view, maybe more when I can get better access.

    Re: 6008/P20

    seems very good, but i am just getting started with it. it is heavier and bulkier, has sharper edges, lenses seem extremely nice. had to buy a -1 diopter from Franke and Heideke in Germany, as i couldn't find one in the US. i faxed them, e-mailed my ccard info and had the thing in 2 days. the finder is quite bright and with the diopter is easy to focus. too damn cold today to wring it out, but i am satisfied. can't wait to try the 110 and 180, and of course, wish there was something wider than 40mm. those ships are huge and you can only get back so far. i've been waiting for a month to get at that Chemical Pioneer, but have been too busy. it has a really odd pair of bow anchor "knockers"
    so far, the phase back is almost the same as the CFV

    John-if you say "almost" what do you mean exactly?
    The images here look great. However different compared to those from the cfv thread.
    I dont know which ones I like better. I found the ones in the cfv thread maybe a tad more alife, more "film"-like, more "heart" maybe a little warmer on the color side? and the ones in this thread maybe a little clearer and "open" maybe more neutral.
    I have no idea why, just my impression - please keep posting more images.

    I'm afraid that this is the downside of the P20 - there is a 1.55 crop factor on these lenses. Perhaps some day you can upgrade to a back with a larger sensor?

    Re: 6008/P20

    way too soon for me to say anything about the backs. i still have to diddle around with the raw conversions; that green is too warm. i thought i had the back set to daylight, but i think the kelvin varied among the shots when seen in C1. i was too cold to be carefully examining the P20 screen.
    what i liked about the CFV was the rich color and dynamic range and so far the P20 seems every bit as good. i certainly no expert however.

    Ah, I see. No, there isn't a larger square sensor (yet).

    Re: 6008/P20

    John from what i have seen is your CFV images tended to be very warm in color temp and the Phase is actually more accurate . Your whites are dead on in these. If anything Phase comes in around 5100 to 5300 kelvin just about perfect in that range. Try it in C1 and you will see. Now if you want to match your CFV files than just adjust the kelvin down a little to the warm side. The DMR was very warm and most folks like images to be on the warm side, it does make it a little more warm and fuzzy looking. Matter of preference.

    On that P20 back under WB white balance, try to create a custom white balance. The P backs allow you to save 3 under the custom setting. This allows you to get a much closer white balance even when shooting to a CF card. I have a lot of people that want a closer color balance when shooting to a CF card and this can be used to achieve this in the Phase One camera back. Sure you can always set a custom white balance in the 3.7 or 4.5 software but this brings the image in at a more accurate balance. I think you will see less yellow in the greens and the over all yellow cast will be reduced, making a much cleaner image.

    Check your PDF that shows this in the Phase One documentation and it will list the steps on how to do that.

    Re: 6008/P20

    thanks for the tips.
    I will set that custom Wb on the back, it is always easier the closer it is in the can. by the way, the CFV was consistently off. in post i had to set each shot down from the as shot (daylight) 5500 to about 4750 and add a bit of magenta

    Guy; i did a quick color balance by eye in C1 and i agree the white looks right on, but the green in the shot is not the same as the ship. when i get a chance i will play around some more.

    if i can get to it (it is 22 degrees right now!) i will take out the XACT2 which uses the same Rollei lenses and i can put on the P20 or the CFV. should make an interesting comparison.

    Re: 6008/P20

    John sneak a shot of a macbeth Color chart in a shot or the Whibal cards. Try to get a reference to WB off of. For me 90 percent of the time I just put the back on daylight when outside and usually it is darn close. The P20 and P25 plus which i have i believe have the same sensor

    Re: 6008/P20

    John try something for me and see if it improves instead of WB off the white , try doing a WB under the anchor the dark shadow area in C1. I noticed a shift in PS when doing that on the black point. Sometimes what can happen is color casts from neighboring colors can spill into the white area and throw things off.

    Re: 6008/P20

    i was being sloppy on the first go around. here is the correct green to my eye and WB was set via the picker off the white shape just below and to the left of the anchor. very simple

    loaded both for a side by side

    Re: 6008/P20

    Well the quality is certainly there no question about it. Having the P25 Plus myself . i just love these 9 micron sensors. i don't know what it is and can't put my finger on it but what i have seen both from Dalsa and Kodak on the 22 mpx backs i just love them. The quality from them is something else.

    Something about BIG FAT pixels. I wish someone with a very technical background in sensor design can explain this to me.
