    Epson Panorama Photo Contest
    on: April 7, 2022 at 6:18 pm

    I think the Photo merge tools are the same in LR and PS, allowing stitching of raw files, and the resulting pano becomes a dng. I have tried PTGUI – it looks very capable but there is quite a learning curve to use it properly, unlike the LR/PS tools which work quite intuitively. I would reserve PTGUI for things LR can’t do well enough, which aren’t many.

    The Panorama PhotoMerge is different in LR and PS. Both the output format and the result differ in my tests. I have more success with PS.

    Re: Phase One Frame Averaging
    Reply #1 on: September 3, 2021 at 6:01 pm

    I am surprised that only a few manufacturers implement frame averaging in cameras. While it is possible to do it in the post, it is quite cumbersome to do it with a larger number of images.

    Olympus and Pentax have cameras that implement frame averaging in cameras. Nikon’s DSLRs can use multiple exposures as frame averaging. AFAIK, only Olympus and Phase One implement gapless frame-averaging, which is often necessary for smooth movements.

    Note that Olympus is limited to 32 images, while Phase One and Pentax have a much larger max number of frames that can be averaged.

    Kevin, thank you for the article about the printer and the early comments. Would like to know how it fares for B&W when compared to P700. I assume that will be part of your in-depth report.

    1. Never use image stabilization on a tripod.

    If I do not forget, I always turn off stabilization on the tripod. When shooting with long lenses, the sensor may “wander” while trying to frame precisely. It makes framing very hard. This is especially true with IBIS. When shooting long exposure, the stabilization mechanism may move slightly which can cause a blur.

    On a good tripod, there is no need for image stabilization. I prefer to turn off everything that is not needed.

    2. Never delete an image in-camera

    Unless it is an accidental shot of my shoes or the inside of the camera, I never delete an image in-camera as I do not trust the EVF or LCD to evaluate an image. The only benefit would be to have more memory (easily solved with more memory cards) and less work in the post (only if a lot of images are deleted). The disadvantage is the accidental deletion of an image.

    3. Always reformat your memory card

    It is good to at least occasionally reformat cards in order to defragment it. What is the advantage of deletion vs. formatting? Some Sony cameras take a very long time to format, but most do it quickly.

    Re: noise reduction

    I prefer DxO PhotoLab 4 (Deep Prime) noise reduction if the camera is supported. The best is to use it as the first step, which converts the raw file to a linear DNG file. If the camera is not supported, then I use Topaz DeNoise AI.
