  1. I have been finding several things about the A6700 that not a single written or video review bothered to mention. No surprise. Every time I buy a camera it is the same. 🙂 I have searched and still not found an answer to my question so today I asked ChatGPT. It gave this answer which is just speculation on the reason(s), but good stuff: The discrepancy in color space options between JPEG and HEIF formats in Sony cameras could stem from several factors: 1. Technical Limitations or Design Choices: It's possible that the implementation of HEIF support in Sony cameras is more limited compared to JPEG. Developing support for multiple color spaces in HEIF format might present additional technical challenges or require more resources, leading Sony to prioritize other aspects of HEIF implementation. 2. Workflow Considerations: Sony might have made the decision based on typical user workflows and preferences. While Adobe RGB is commonly used in professional photography and printing, the majority of consumers may not require it for everyday photography. By offering Adobe RGB only for JPEG, Sony might be catering to the needs of photographers who specifically request this option for certain types of work. 3. Market Demand and User Feedback: Sony may have gathered data indicating that the demand for Adobe RGB in HEIF format is relatively low among their target customer base. If the majority of users are satisfied with sRGB for HEIF images, Sony may choose not to allocate resources to implement Adobe RGB support in HEIF format. 4. File Size and Compression Efficiency: HEIF is designed to offer better compression efficiency compared to JPEG while maintaining high image quality. Using Adobe RGB in HEIF format could result in larger file sizes due to the wider color gamut, potentially undermining the benefits of HEIF's compression efficiency. 5. Compatibility and Standards: While Adobe RGB is widely used in certain professional workflows, sRGB remains the standard color space for most consumer electronics and online platforms. By defaulting to sRGB in HEIF format, Sony ensures broad compatibility with displays, printers, and online services. Overall, the decision to offer Adobe RGB for JPEG but only sRGB for HEIF in Sony cameras likely reflects a combination of technical considerations, user preferences, market demand, and compatibility requirements.
  2. I accidentally posted this in the moribund Sony/Minolta forum, but I meant to post it in this slightly more alive forum instead. Sorry. I could not find a way to delete the earlier mistaken posts. Last month I bought a Sony A6700. I still have mostly m4/3 gear and still mostly prefer it, but I was sort of bored and felt like trying something else. Anyway, I have been playing around with HEIF photos. Sony, Canon, Nikon, Fuji, Panasonic, etc. these days produce 3 types of photo files: raw, 8-bit JPEG, and 10-bit HEIF. With the A6700 the HEIF choices are: 4:2:2 or 4:2:0. And you can select among 4 compression levels (same as for JPEG): Extra Fine, Fine, Standard, Light. With Sony HEIF you can use sRGB or HLG (Hybrid Log Gamma) that uses BT.2020 color, but not Adobe RGB (choice is grayed out). With JPEG you can use sRGB or Adobe RGB. I wonder why Sony HEIF does not allow Adobe RGB? I have been playing around with HEIF 4:2:2, Fine, sRGB. Lightroom Classic supports it.

  4. Just to be clear, you have used Mac Photos and iMazing Converter to quickly show all the photos in a folder (raw, HEIF, JPEG, TIFF), easily see photos full-size, easily see EXIF data, easily compare side-by-side, easily cull (delete), etc. as I wrote above, right? You are saying these programs are very similar to Faststone and XnView MP? The description for iMazing Converter sounds like it does none of those things. It seems to just convert HEIF/HEIC to JPEG.
  5. Unfortunately, the big, multi-function Photos app is not what I am looking for. Thanks for replying.
  6. Does anyone know of a good, fast photo browser for Mac that also handles HEIF files? I just need something for quick, easy culling. For example, on Windows I have used Faststone for years to do it. It quickly shows all the thumbnails in a folder. I can click on a photo to see it full-size and also easily see the basic EXIF info (camera, lens, ISO, shutter speed, aperture, etc.). I can easily scroll through all the photos seeing them using the mouse scroll wheel or keyboard arrow keys to go to the next one or previous one. I can also easily see side-by-side photos to compare them. They are linked so I can move around in the 2 photos and they move together, I can zoom in, and so on Faststone is only on Windows though and it, unfortunately, does not support HEIF files yet. I also use XnView MP on Windows and while I prefer Faststone, XnView MP supports HEIF files so I have been using it recently. It can also do all the stuff I mentioned above about Faststone, but the UI is not as polished or as easy to use. Unfortunately, the Mac version has bugs with HEIF so it is unusable on Mac. Anyone know of a program I can use? Preferably inexpensive or even free. Thank you.
  7. I thought the Leica Monochrome, Type M246 was a digital camera. Are these film scans?
  8. Yep, that and other things. See the photos of the book in the link.
  9. Here is a thread about a Blurb B&W book: B&W Blurb book received -- not so happy
  10. <p>I ordered a Blurb book sometime back and also had problems with it. Somewhat different problems than the ones in this thread, but still important for people to know about who might want to make a Blurb photo book. After more research and discussion on a different forum also it seems to be a problem with the type of printers Blurb uses. I don't know if anything has changed since I made my book. Anyway, just so that others who stumble upon this thread can get a more rounded view here is the link to my thread also:<br> <a href="/digital-darkroom-forum/00csF6">http://www.photo.net/digital-darkroom-forum/00csF6</a></p>
  11. <p>Since it seems the poor quality of Blurb's B&W photo printing is because of the inherent characteristics of the HP Indigo printers they use I am wondering if anything has changed to make big improvements to the quality in the last 6 months since I started this thread?</p>
  12. <p>By the way, I have a thread about my experience with a Blurb B&W photo book:<br /><br /><a href="/digital-darkroom-forum/00csF6">http://www.photo.net/digital-darkroom-forum/00csF6</a></p>
  13. <p>I read your post and the responses with interest because in 1999 I posted a very similar question here on photo.net:</p> <p>http://www.photo.net/bboard/q-and-a-fetch-msg?topic_id=23&msg_id=000h1J<br> <br />You would probably like to read my old thread too. :-)</p>
  14. <p>I didn't expect a very high quality, expensive photo book, but I did expect the photos to be at least as good as what I can see in photo magazines here in Japan and inexpensive photo books I see at the bookstore. The photo quality from Blurb is not much better than a newspaper though (paper is much better though) and yet even with the 25% discount I paid $56. I had planned to buy more after I saw the first one to give as gifts and for those I would have not got the discount so the price would have been $67. For that kind of price I definitely expected much, much better. Anyway, Adobe and Blurb are doing a disservice to photographers, I think.</p>
  15. <p>My first SLR was a Mamiya/Sekor 1000 DTL with Mamiya/Sekor 55mm f1.8 lens. I bought it in February 1974 when I was 17 and it took lots of saving from my after school job to pay for it. I have such good, warm, nostalgic feelings about that camera! I sold it in 1976. Enjoy yours!</p>
