    Trying to find a solution for triggering flash

    Which digital back? Most relevant Phase One digital backs would have two ports – one to accept inbound triggering from the lens to sync the exposure of the back with the opening of the lens, and another one to provide output flash triggering sync'd with the exposure of the back (and therefore...

    MFD 2025 – state of the industry and outlook

    Feels a bit pseudosciencey to me. The underlying science is real that some psychological effects respond in non linear ways. But that doesn’t mean all effects are like this. Do you personally only notice a meaningful change in lens focal length when it doubles or halves from another lens? I...

    How useful is having a second body?

    It's not crazy. We have clients with 3+ backs. For example Standard Color, IR converted color, and achromatic. Very obviously not a sensible approach for everyone but if the passion and budget is there the additional weight/size is pretty minor.

    Stitching by Shifting versus Twisting

    Generally when I do flat stitching behind the image circle I feel like I'm "photographing". When I'm doing pan-and-stitch I feel like I'm doing "computational imaging". These are not perfect words for what I'm trying to describe... there's a feeling of intentionality, relaxation, and connection...

    So, who is buying a Alpa these days?

    Not specific to (or at least not limited to) comparing those brands, a good functional lens to evaluate what category a brand is trying to fit into — cheap, consumer, professional, luxury, ultra-luxury — is to look at the box it comes in. The below are rules of thumb; plenty of exceptions to...

    Phase One IQ5 – Sony 247 MPX – 3:2 – will you get it?

    I don’t think I would describe Phase One’s historic timing advantage as “tiny” looking at the timing for the actual shipping-in-meaningful quantity timelines for the crop 50mp, 645 100mp, crop 100mp, and 645 150mp sensors. I was at the Hong Kong launch of the IQ250 (first with 50mp cmos) back...

    How successful have recent Hasselblad product introductions been?

    Capture One sessions can: - sync metadata to XML in real time - pack the metadata together with the raw (eip) - sidecar the metadata in a subfolder Between these three options there is not a metadata workflow I’m aware of that isn’t possible. What is it specifically you can’t do with C1 you...

    Hasselblad X system crop factor

    That’s the point of a visualizer though; depending on what/how you shoot the short, long, or diagonal may be the most appropriate comparison. When I shot weddings a vertical portrait was my frame of reference (pun intended). I tended to crop those to 3:4 or even 4:5 anyway, so the long side or...

    Hasselblad X system crop factor

    If only someone had a tool to visualize this focal length equivalence and was allowed to post links.

    Arca Swiss D4 head variants?

    “Nothing stops you or any other dealer from doing the same.” Steve, would you personally continue to actively participate at the same level if the forum was exclusively sponsored by your competitor and you were not allowed to do anything that sponsor vaguely perceived as competitive? Can you...

    Arca Swiss D4 head variants?

    All of that history is accurate – some great memories there. The forum owes CI for supporting it during the pandemic. I guess we disagree about where a reasonable line is to draw on what constitutes commercial promotion vs informational answers. The admins deleted my post where I referenced...

    Arca Swiss D4 head variants?

    DT provided financial support for many years as a site sponsor. For most of the life of the forum many sponsors were allowed simultaneously - we were one (as was CI). I’ve also personally spent a thousand or so hours participating in discussions here, racking up ~4000 posts. But in the 2020...

    Arca Swiss D4 head variants?

    lol. Forum admins won’t even let me mention the most comprehensive write up of Arca Heads because it competes with Capture Integration, even if I don’t link to that article what a joke admins: please feel free to delete my account and all previous posts if that’s your position

    Phase ONE 28mm lens f4.5

    It’s the weakest Phase One lens. Whether it’s performance is acceptable to you depends on the resolution of your back, the sensor size of your back, the aperture you’re shooting at, and your personal level of scrutiny, and whether you have any subject matter of importance in the corner. If...

    IQ5 rumors

    Speaking from my experience designing the systems that are used for the vast majority of still film scanning at US libraries, museums, and archives – precious little large format film was shot in a way that maximized its possible technical quality. The reasons varied - Film holders weren’t flat...

    IQ5 rumors

    Love the strong feelings about theoretical aspect ratio in a theoretical product – great holiday reading. For what it’s worth I’ve been cropping most of my marque images to 16:9 over the last few years. Maybe out of appreciation for cinema, maybe because it looks nicer on a wall to me, maybe...

    Angle of view for stitched photos

    That’s exactly what the DT Visualizer (linked above) does. Enter any combination of sensor, lens, and stitching configuration and it gives the AOV, equivalent focal length (based on vertical, horizontal, or diagonal) in another format. It also shows you the result visually. Maybe you didn’t...

    Angle of view for stitched photos

    I did the coding for that if you have any questions. When doing stitching with stitching you’re basically just making a physically larger virtual sensor. For example if you stitch an IQ4 150mp ~51x40mm sensor to do a left-right stitch of +/- 12mm shift on the long side your virtual sensor size...

    Hasselblad 100C and 35XL

    When shooting color cameras for black and white output the underlying color can matter a great deal if you are using larger B+W slider adjustments. For example if you’re darkening the sky by pushing down blue tones (roughly equivalent to using a yellow filter in the field) then blue color noise...

    Rodenstock 23mm on the CFV 100c?

    Our Image Circle Visualizer answers this directly. Can’t link to it due to forum rules.
