    Jim, Nice image captured in good light (overcast skies?).

    How sensitive is the Betterlight scan back to IR relative to visible? Thanks.

    I'm not sure if there's a measurment.. but very is what the impression is.. There's no IR block filter (or AA) in front of the sensor array. you need to put one in front of the lens (or behind) to get visible light only.

    .. and yes.. overcast skies.. i rarely take a camera out if the sun's out

    Hi Jim,
    Love the tree bursting out of the pavement and it is huge giving a great sense of time. Interesting with the IR and the color layers and at what point do you do the stitch?

    This is shot with the Betterlight scanning back and the pano adapter. There's no stitch. it's shot as one continuous scan. Also, there's no blending done.. the Betterlight sensor captures both visible and IR light at the same time

    Hey, I took one there too! (Only mine is in color ) The original file is a 2.8 GIG tiff and is almost 18,000 pixels wide(!) -- so this has been downsampled significantly

    Unbelievable! Before even reading the caption I recognized the content of the photos!!! I was stationed there in 1971 and later after Vietnam. I recall discussions of closing the base as far back as 1978 but it was determined that it would be an environmental nightmare to remove all the ordnance from the ground. Anyway, I now feel very old and in need of therapy. BTW: The washed out coloration in the original photo says a lot about the subject history.

    Jim,
    I have been eyeing that back, but I fear that my LF days are over especially since most of my pictures are taken during long walks these days. I should plan out some forays by auto some day to justify carrying larger caliber gear :-)

    John, your Navy yard CFV images are stunning! Definitely folks, if you don't wander over to the MF section on a regular basis, now may be a good time to do so -- John put up a phenomenal series!

    could not agree more. Makes me hope I can shoot something of value with my new CFV back. Certainly the technology won't be the limiting factor.

    Jack, how in the heck do you post such a wide shot in a thread? I though 900 pixels was the limit.

    I'll be testing a P45+ to see how it reacts shooting IR. I'll post my findings and some test images soon.

    Great shots of the army base guys. It does bring back a lot of memories. I remember knocking over a barracks backing up a tractor trailer back in the day. Luckily nobody was inside

    Sorry for the delay of posting here, but Doug Peterson and I were both testing the P45+ IR. Here is one of Doug's images he shot in Miami. Lance Schad or I can give you more information on it if you like.

    Re: IR Pano via Betterlight and Ebony SV 4x5

    so how was this accomplished? (removal of the IR cut filter?), and is this something that will be offered to owners of P45's?

    Re: IR Pano via Betterlight and Ebony SV 4x5

    ... i've been very impressed with the speed and involvement that both Sinar and Phase seem to give on this (and other )forums.

    I really love the Leaf back i have.. , and any question I've asked Steve have been answered quickly... but the feeling i've always had, is that corporate support from Leaf isn't forthcoming. I've seen some responses in Luminous Landscape.. but they're typically directed at the big commercial players. Any email directly to Leaf people internally seems to either disappear, or take forever to get very short, curt and sparse responses.

    I'm sure there are other Leaf users out there, but there's very little feel of a 'community' anywhere (the Leaf forum is about as dead as one can be)

    Jim,

    To get all of the details you can look at the link on our web site. Doug has posted the details of that particular shot. The P45+ had the IR filter removed from it and was replaced with glass. You can order it directly from a Phase One dealer, but it will add a couple of weeks to your delivery time. It's just that they pull what would be a normal P45+ off the production line before the filter is installed and insert clear glass. It then has to be recalibrated and focus checked.

    Re: IR Pano via Betterlight and Ebony SV 4x5

    Jack and Jim: if you have a chance to post some 100% crops of those amazing panos I would greatly appreciate it. I took a Phase One scanning back out on an IR shoot a while ago and I'm sure you can sympathize that my first go around with such a system was frought with rookie mistakes. I'm wondering specifically about the sharpness at 100% and what lenses you've found focus the infrared light closest to the primaries.

    Also, I almost always target a monochromatic output. Maybe I'll step into some false-color IR soon. But in the meanwhile I've been spending a lot of time going back and forth between exposing exclusively for the red channel with daylight WB, and exposing for the luminosity after a custom (and quite severe) WB. I've not made up my mind yet, and would appreciate input from other IR shooters. My feeling in general for digital IR is to expose only for the red channel and extract just the red in post. In the past this has had a meaningful impact on noise and shadow detail, but this seems not the case using the P45+IR.

    As for my most recent shoot with the P45+IR I can't tell you just how pleasant it was shooting IR with this camera compared to the scan back, film (HIE, macophot 820, SFX200), or 35 digital I've shot in the past. I've always had a passion for infrared, but its not been so leisurely to capture images that satisfy me. Here are a few further examples from this weekend.

    If anyone is interested I can post a raw, because to me that was the best part. The flexibility of the resulting magenta-cast file is just incredible. Any cut-off in detail you see in these images was a choice; all of them had generous detail on both ends of the histogram.







    Hey mods, is it okay to post that many large pics in a row?

    Re: IR Pano via Betterlight and Ebony SV 4x5

    By the way, as noted in the entry on this back on captureintegration.com these files are all heavily photoshopped. The most visible effect is that of a glow effect:
    1) duplicate layer
    2) set layer blending to overlay
    3) gaussian blur the layer by 5-50 pixels
    3) reduce layer opacity to 30-70%
    4) mask out layer in extreme highlights to preserve last zone of detail

    The shot of the roof against the sun was taken with the assistance of HDR, though once I had gone through the hour of work to combine 3-stitch X 3-exposure image I found that one of the single horizontal exposures worked almost as well. The IR response of this camera is quite compressed in the histogram, allowing for a LOT of scene contrast while maintaining shadow/highlight detail.

    Hi Marc:

    900x900 is only the limit for an attachment. If you use the gallery, you can upload up to a 1200 high x 2400 wide jpeg, jpg, or tif as long as they don't exceed 2meg in total file size, then link to it or embed it (as I did with this one) in a thread.

    Cheers,

    Re: IR Pano via Betterlight and Ebony SV 4x5

    Hi Marc:

    First, let me correct the above -- you can upload ANY pixel size, the only limit is 2MB per image. That corected, full details on using the gallery are in this thread in my post #4: http://forum.getdpi.com/forum/showthread.php?t=54. Next, more specific details can be found in the FAQ's, and here is a brief:

    1) Upload your image to the gallery, any size, only limit is 2MB
    2) Forum software will upload the full image, and at the same time create a max 900x1200 version.
    3) In your gallery you will have a thumb and the 900x1200.
    3a) If you click on the 900x1200 image, you will get to the full size image you uploaded.
    4) At each of these images is a bb-code link string underneath.
    5) Copy this link
    6) In your thread, use the embed image icon, the one up top that is a mountain with a sun in it
    7) Insert the copied string in the dialog box, and presto, you are done.

    Cheers,
    Jack
