    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.

    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.

    Re: NEW Article – Fuji Film Simulations JPEG vs. Capture One From A RAW File
    Reply #5 on: February 14, 2021 at 7:44 pm

    Thank you for the article, Kevin. Have you considered using Fujifilm X Raw Studio? You connect the camera to the computer and use the camera’s excellent film simulation engine to convert the RAW files to TIFF (albeit only 10-bit data).

    It sounds a bit complicated, but the results are quite nice.

    I would like to know how “Srdjan” is pronounced, if you would be so kind as to provide this.

    Re: Olympus?

    I have ‘rediscovered’ my Olympus system and acquired the latest new M1 cameras and some excellent lenses. Using optimal exposure and Live ND (aka frame averaging), it is possible to create images that are very close to the IQ of FF systems. IMO, the main differentiator between systems is the lenses. My FF and MF systems are currently taking a break. :).

    Re: What’s the verdict on DxO PhotoLab
    Reply #8 on: January 1, 2021 at 7:21 pm

    I have just downloaded the trial version (Elite). My main interest is how well does it fit within my LrC/PS workflow.

    DxO Photolab 4 has very interesting noise (DeepPrime) and lens correction. It is possible to export the corrected file as a linear DNG, which is more flexible than a TIFF output. I intend to use it occasionally as a first step in LrC and continue working within LrC and PS to refine the image further.

    Unfortunately, many cameras are still not supported by DxO Photolab 4.

    It seems that is the annual contract cancelation: “Should you cancel after 14 days, you’ll be charged a lump sum amount of 50% of your remaining contract obligation”.

    BTW, it is worse with Capture One (annual-monthly subscription): “This subscription plan cannot be canceled before the 12-months contract expires.”

    For Adobe’s month-to-month plan ($9.99 for PS and LrC) cancelation: “your payment is non-refundable, and your service will continue until the end of that month’s billing period”.

    Re: Exposure Technique for Mirrorless using Zebras
    Reply #10 on: December 30, 2020 at 11:07 pm

    What is the point of the histogram when we have highlight warnings (zebras or blinkies)? For ETTR, there is less information in histogram than in highlights warnings. With highlight warnings, we can see whether relevant highlights are being clipped, which we cannot with histograms.

    Highlight warnings can be more intrusive than histograms, but some cameras enable highlight warnings only with a half-press.

    Re: Does pixel-shift increase resolution?
    Reply #11 on: November 24, 2020 at 3:33 pm

    I just bought the Panasonic S1R FF mirrorless camera. It does an 8 shot in camera pixel shift outputting a 187 megapixel raw image. I don’t think there is a camera today that matches it. Great detailed file at 55″ on the long side out of the camera. It has the usual restrictions of movement. This camera seems to be under the radar but it is a fine pro level machine.

    Leica SL2 now supports pixel shift to 187 MP as well. Comparisons on LUF claim that it does a bit better job of creating the 187 MP than S1R. Both SL2 and S1R have motion blur removal. On SL2, it works quite well for slight branch movements, though it reduces the resolution a bit.
