  1. <p>I'm already well, Wouter. I had a somewhat mopey day at home, but now I'm back to home renovation stuff. ;-)</p> <p>I do like MS's representation that Win10 is an attempt to have a durable, infinitely upgradeable OS. We'll see how well it makes the transition to future computer architectures. Sad to retire Win7, though, because it has been very stable for me, and I've already paid for it.</p> <p>Bebu, I feel your pain! I tried uninstalling and reinstalling the drivers. I got rid of the lavender and eggshell color scheme with funky graphics, but now my NEC monitor is completely offline again, and my other two monitors are uncalibrated (and conspicuously different from each other).</p>
  2. <p>Thanks so much, everyone!</p> <p>Sadly, Wouter, the unified driver you link to is exactly the same one I installed -- ver. 15.201.2401, dated Dec 1, 2015. The one you link to, Eric, is an earlier version of the unified driver, dated July 16, 2015. The December 1 version, which I assume is the latest, still offers no 10 bit support. Moreover, I have some sort of installation issue, whereby the driver doesn't keep working. Win10 seems to shut it down, and then I have what appear to be 7 bit (or less) graphics, which look really gunchy. Then when the ColorMunki monitor profiles are applied, everything turns to a lavender and eggshell color scheme (should be light gray and white). I'll give AMD a call sometime in the next few days (really busy with other stuff) to see if they can figure out what is going on. (Maybe an ISV driver is what I need -- talks of 10 bit support.) Xrite (ColorMunki) might be my next call. And heck, I have a cousin who is a big-wig programmer with Microsoft. I might contact him too.</p> <p>I have to agree with you, Wouter, that the transition to Win10 has been smoother than I expected. (I have yesterday's version of Win10, BTW. And yes, I'm running 64 bit.) My applications all seem to work, more or less, which is rather remarkable. I think there are some registry issues I'll need to track down and hopefully clean up -- maybe a dozen executables that can't be found. What I hate, though, is having to go through this painful process when I have absolutely no complaints nor feel any limitations with Windows 7 Pro. In fact I prefer 7 Pro to 10. (I've been running 10 on a laptop for a while now, so I'm already somewhat familiar with it.) I decided to work on the system yesterday while recovering from a colonoscopy, leading me to ponder which was worse -- the colonoscopy or the Windows 10 upgrade. I honestly can't decide. </p> <p>Anyway, it's back to work today on a house we're renovating. I have a hardwood floor to lay. I'm not sure how long I'm going to be living with my new lavender and eggshell color scheme!</p>
  3. <p>It IS a nice card! I guess I can call AMD and ask them when they expect to have a Win10 driver for it. I don't really need the 10 bits for most graphic work.</p>
  4. <p>Not on FB...</p> <p>I knew this would be a PITA when I started it. However, I don't want to be stuck with an OS without update support. It's a lonely and scary place to be.</p> <p>With a bit more poking around, I found a link on SoftPedia to an AMD FirePro and FireMV Unified Driver. Not totally trusting SoftPedia, because none of these sites are completely trustworthy, I searched the AMD website for "FirePro Unified Driver" and found this link:</p> <p>http://support.amd.com/en-us/download/workstation/multi-view?os=Windows+7+-+64</p> <p>The release notes indicate the driver will drive my card under Windows 10. However, it warns, "Note that this driver has general support for Windows 10 for listed Workstations products. The driver is not recommended for full advanced workstation features (see more information in section <em>Workstation Features (Win10). We recommend NOT to upgrade to Win10 if you are using advanced workstation features.</em>)"</p> <p>So the driver at least brings up my monitors. ColorMunki calibrations are hosed for now. It looks like I have to give up 10 bit color depth, which is not supported. Damn. It was hard to find an affordable monitor/card combo that would support 10 bit. But at least that gives me minimal functionality.</p> <p>Any suggestions for a replacement graphic card to drive the NEC MultiSync PA241W in 10 bits per color channel (a.k.a. 30 bit)?</p> <p>Thanks!<br> Sarah</p>
  5. <p>Hi all,<br> I'm totally frustrated and could use some friendly help. I took the plunge and reluctantly "upgraded" from Windows 7 to Windows 10. The compatibility search utility detected no compatibility issues beforehand.</p> <p>The driver for my ATI card no longer works. I tried reinstalling, but there seems to be a compatibility issue with Windows 10. I see Win 10 is not cited as a supported OS. When I search the Radeon/ATI site for available drivers, it says there are none. I also tried running the auto-detect driver installer available from Radeon. It correctly identifies the card and OS, but it says there is no driver.</p> <p>A search for Windows 10 drivers for this card brings up a lot of hits, but they all seem to have web-of-trust profiles suggesting malware and such.</p> <p>Any thoughts? Do I have to buy a new graphic card to take advantage of this "free upgrade" I didn't want?</p> <p>Thanks for any leads or insights!<br> Sarah</p>
  6. <blockquote> <p>So how do we go from being a young girl with intact, healthy instincts superior to those of her parents (the child just knowing not to sit on a lion) to being a parent who, with instinct lost to them, would put their kid on a bison, or walk up to a brown bear to take a picture? How is it that instinct is lost?</p> </blockquote> <p>"Hollywood" teaches us to regard these animals as lovable teddy bears, ironically with shows like Daktari (which I loved as a child). As children, we instinctively fear everything we don't understand -- people besides Mommy and Daddy, new foods, house cats, bugs, etc. And then our parents (and Hollywood) teach us what we can trust. This doesn't change after we grow up. People still fear the mysterious and unknown.</p>
  7. <p>Gah! Always check your work! (It would make no sense for Fi to be greater than 2x F! In my haste, I neglected to divide by 1.5.)</p> <p>So substituting and solving, you get a focal distance of 58.3mm, meaning you need 23.3mm of extension. You can probably get that from a 20mm extension tube and 3.3mm of extension from the focusing mechanism. And thus Jochen's intuitions are pretty darned good!</p> <p>BTW, the correct focal distance setting on the lens with a 20mm extension tube would be 0.4 m. </p> <p>G'nite!</p>
  8. <p>Edward is correct, but I believe you need a number.</p> <p>Focal distances are calculated thusly: 1/Fo + 1/Fi = 1/F, where Fo is the focal distance to the object (your slide), Fi is the focal distance of the image, and F is the focal length of the lens. So 1/35 = 1/Fo + 1/Fi. We also know that Fo/Fi = 1.5 (the crop factor). Substituting and solving, I get Fi = 87.5mm. If your lens focuses to infinity at Fi=35, then with your lens focused to the infinity mark, you will need 87.5 - 35 = 52.5mm of extension tube. And then the lens extends via the focusing mechanism, so some of that 52.5mm can be from the focusing mechanism itself. If the lens focuses as close as maybe 0.3 m (300mm) then it can extend to 1/(1/35-1/300) = 39.6mm, meaning the barrel extends 4.6mm. So if you put a 50mm extension tube on the lens, you should get a 1.5:1 magnification ratio somewhere in the middle of the focusing range of the lens.</p>
  9. <p>WOW! And WOW!!</p> <p>This has the same feeling to me as watching "Forbidden Planet" as a kid. I savored every image and read the annoyingly repetitive narrative, wondering, "Will they be able to enter one of the shuttles?" Tantalizing!</p> <p>I have to smile at the culture of the Russian space program. The Russians are often brutally practical. One photo is particularly interesting -- the first shot of the cockpit. The pilot and copilot seats would appear to be wooden.</p> <p>God, I would love to see that hanger in person! Matt, maybe we can shoot the facility together!</p> <p>WOW!</p>
  10. <p>Your story reminds me of what it took to get this candid portrait:<br> http://graphic-fusion.com/phcherokee01.htm</p> <p>I'm not saying this is the greatest photo of all time, but I really wanted to capture this man's beautiful (but fleeting) laugh. I think I took so many shots he was starting to get nervous. And then I managed to capture what I was after. I later showed him the one good frame and explained why I had to take so many shots to get it. Sweet guy! I'm glad he was so patient with me.</p>
  11. <p>The dimensions are standardized per ISO 518:2006. See here:</p> <p>http://camera-wiki.org/wiki/Hot_shoe</p> <p> </p>
  12. <p>My 5D measures around 2mm, give or take 0.1 mm (hard to measure). The thickness of the metal measures about 1mm, give or take. My guess is that this is the standard -- 1mm metal and 2mm gap. I don't have a more modern camera (except for my 40D), but I would be utterly gobsmacked if they were any different.</p> <p>Where does this 2.4mm cover come from? I suspect it fits nothing -- defective.</p>
  13. <p>The dimensions of these shoes are very standard. The basic design goes WAY back. Just in my collection, here are some early cameras with shoes of this design: Zorki 1 (ca. 1950, clone of an earlier Leica), Leica IIIf (1950's), Universal Mercury II (ca 1945), Kodak Monitor Six-20 (1946), and even the very cool Perfex 44 (1939) which surprisingly featured a HOT shoe! The only real difference between hot shoes is the layout of the terminals. But they're all the same physically, as far as I'm aware.</p>
  14. <p>There are a lot of people with more camera than sense at Yellowstone. I remember someone with a Canon 100-400, zoomed all the way out, stalking a bison. He got as close as maybe 20 ft to get his photo. Maybe he was getting a close-up of its eye? Another person with a huge 500'ish lens (Nikon photographer) was maybe 30 ft from a bear. I think the point was (1) to show off expensive gear and/or feel good about owning it, and (2) to document one's own bravery/stupidity, staring danger in the face and laughing, so to speak. Or maybe the big lenses doubled as clubs, to be used for beating off the angry beasts.</p>
