    I believe the Zoom to Fit will only zoom up to the full preview size. That is 25% of the actual raw image size. If your window is smaller than what is required for the full preview that option will shrink it.

    Capture One only works with 25% of the full raw data during manipulations. Then when processing it read in all of the raw data. This is one of the things that gives Capture One its speed. When you zoom to above the 100% preview it is not giving you more detail, it is just interpolating the preview pixels upward. Starting with the release of 4.0 it will be able to use larger previews and will be working with all the raw data even during the adjustment stage.

    I'm not sure I understand what you mean. When I had a 4:3 19" monitor the 'zoom to fit' pretty much filled the preview window. When I moved up to a 24" 16:9 monitor, the preview screen is nothing like 'zoomed to fit' as you can see from the screen grab. The image is a lot smaller than the preview space. I need to put the zoom to around 120% to get it to fit properly.

    My understanding is that at 400% C1 shows actual pixels - i.e. 100% in any other app! - and is not interpolating at all, but at any other level it does.

    Like many thousands of others, I await with bated breath the release of the much delayed v4!

    Your new bigger monitor has more pixels. But the photos from your camera still have the same number. While a 25% sampling of the full data was enough to fill your older, lower resolution monitor; it is not enough on your new one.

    Many people are finding the same thing, and today's computers are getting fast enough that they could work with a bigger dataset. It is just that Capture One up to 3.7 is hard coded to work with only 25% of the data no matter the speed of the computer or the resolution of the monitor.

    My understanding is that at 400% C1 shows actual pixels - i.e. 100% in any other app! - and is not interpolating at all, but at any other level it does.

    400% of the preview is a special case. Capture One ceases to use the optimized 25% preview and goes straight to the raw data. In doing so it suffers a huge performance hit. At 400% adjustments stop being realtime and have a noticeable delay before being reflected in the preview.

    It was Phase One's decision to have Capture One work with a 25% subset of the raw data. This it what gave Capture One its "feel", the instantaneous feedback to changes, the ability to just "play" with the controls to see how the image is affected. This was not possible using the full data on the machines of the day when Capture One was being designed. The speed of computers has greatly improved since then (and as I understand it, the processing algorithms of Phase One's programmers), so the new release will be able to use all of the captured data, and with greater efficiency.

    I understand that, but why is it called 'Zoom to Fit' when it doesn't fit anything? It would overlap a low res monitor and not fill a high res monitor!
    In what sense is it 'Zooming to fit'?
    In Photoshop, 'fit on screen' means exactly that no matter what the res of the monitor. I appreciate that PS is working with tiffs or jpgs and it's not doing on-the-fly conversions, but still.....

    I'm not seeing the behavior you describe. Maybe it would have been better called "Shrink to Fit". But it does follow this predictable pattern: If the window is too small to show 100% of the preview pixels it shrinks the image until it has a small boarder around the edges of the longest dimension. If the window is large enough to zooms the preview to 1:1 (100%) no larger.

    I just tried with various resizings of my Capture One window. It did the same thing each time.

    Sorry Christopher, I misunderstood what you said. I thought you meant that the same number of pixels were being used, i.e. 25% of the full image, so I couldn't see how it could possibly be 'Zoom to fit' preview as it is called in C1.
    So, in fact from what you are saying, it should be called 'Zoom or shrink to fit as long as you don't have a large monitor'! If you do have a large monitor, then the facility is useless!
    I presume this will be sorted in v4.
