  • Based on Bill Claff's testing as posted on PhotonstoPhotos.com (and DXOMark's), there is no evidence of any such "compression" going on in Pen-F raws. You could make an argument for a small amount ...
  • I just got back from doing a day-long hike in the Grand Canyon with my EM5, Oly 12-40mm f/2.8, Panaleica 25mm f/1.4 and the Oly 75mm f/1.8. Over the course of a day of hiking (strenuous or not), ...
  • Glad you found it to be of value. As for the free converters, I'm partial to RawTherapee. My post, however, was in response to the comment in your original post: I've used Lightroom, Photoshop, ...
  • Contrary to the claim made in the original post, OV3 does a poor job of optimizing image DR compared to ACR/LR (and probably other raw converters). It also applies more sharpening and noise ...
  • The video doesn't credit Ryan Brenizer, the photographer who popularized the method and under whose name you can find lots of information about the method. See here to start with. Of course, there ...
  • Don't forget that it's not currently possible to combine IBIS and pixel shift. Combining them will require another processing and IBIS control breakthrough.
  • You've gotten some responses already regarding the total time required for producing the individual frames at a fast shutter speed plus readout time and how the goal of 1/60 sec total time is ...
  • Replied in That ...
    Interestingly, the Panny announcement claims that the S1R is targeted at stills photographers, but that's probably a topic for another thread. I think the success of the Sigma 18-35mm (APS-C) zoom ...
  • Thanks! I must have accidentally hit that toggle. Wasn't aware that it was an option.
  • Replied in That ...
    I'm exclusively a stills user and, as explained, this lens hits the sweet spot of my shooting requirements. I'm sure there are plenty of others who, like me, have little interest in ultra wide and ...
  • Replied in For instance...
    See below (notice how my screen name and not the thread/post title is displayed):
  • Created discussion thread Weird threaded view behavior
    In threaded view mode I'm now seeing the author's name instead of the posting title in the the thread tree. I just noticed this change this morning but don't believe I've done anything myself that ...
  • Replied in Design ...
    To each his own... My Oly 12-40mm is pretty much glued to my camera as my general-purpose lens. For my requirements I've found that I almost never shoot with it above 25mm but frequently wish that ...
  • Very few monitors have a gamut larger than aRGB. However, most high-end printers and even many consumer-level printers have at least some gamut that goes beyond aRGB. (I do quite a bit of printing ...
  • Adobe Camera Raw (ACR). You can output to any number of spaces but I normally output to ProPhoto, especially when dealing with colorful scenes.
  • Replied in That's odd
    The Oly/Panny pixel shift based HiRes mode has always resulted in raw files that are 4x the size of the sensor's native resolution (64mp for the EM5ii HiRes output and 80mp for the 20mp sensor ...
  • Replied in Herd instinct?
    Even in the "late" film era, medium format was pretty dominant in the professional wedding, commercial, portrait markets. I assisted two different wedding photographers in in the early 80's and ...
  • Replied in Herd instinct?
    "Almost every professional"? Yes for newspaper journalists (eventually) but certainly not in the early 135 era. Same applies to pro sports, street photograph and similar action requirements. No ...
  • Replied in Thank you!
    In that case I know what you're talking about. "Worms" are noise. For example, here's a 300% crop of one of the images in this post. I've made additional adjustments to emphasize the worminess: In ...
  • Replied in Thank you!
    Sure, I've done that kind of basic comparison numerous times but I'm not aware of "artifacts" generated in ACR that aren't generated in OV3. Perhaps you could describe what it is I should look ...
