  1. <p>Les, instead of using their download page which might auto-detect your OS, manually download from their front page about half-way down:<br> <a href="http://www.hamrick.com/">http://www.hamrick.com/</a></p>
  2. <blockquote> <p><em>"The photographer description of those pictures includes my past institution (which is not the case with his other clients) and is highly searchable."</em></p> </blockquote> <p>Not much you can do if he's not responding to your email, and without knowing the content of the initial email, you might, in the alternative, request the photographer to alter your name and remove references to your past institution which will at least make it less searchable. <br> <br> In fact, photo.net will accommodate a name change for exactly this purpose which one would expect any reasonable photographer to accommodate likewise. </p>
  3. <p>There are many problems associated with developing a universally acceptable continuous AF system.</p> <p>Imagine if you wanted to track a single individual in a crowd who is moving laterally, and away from you, with others crossing between the subject and your camera. This is just one scenario where it'd be virtually impossible to design a completely hands-off focus system and be able to achieve satisfactory results. </p> <p>Your best bet is to use a wide angle lens and set the aperture to obtain a DoF in such a way as to include the area your kids will be playing in. </p>
  4. <blockquote> <p><em>"If I request compensation, what's a fair amount? I was thinking a standard rate x 2 as a punitive measure."</em></p> </blockquote> <p>I would simply send an invoice detailing the cost for the use of the image based on the duration of its use. A fair dollar amount will depend on whether your purpose is to do business or to punish the act of infringement and its removal from the offending site. </p> <p>If you want to do business, then I'd probably start with a few hundred dollars for a non-exclusive licence per year for its continued use plus one elapsed year. Or, in the alternative, demand a one year licence fee and its immediate removal if you don't want the image used for that purpose. </p>
  5. <p>It's common for semiconductors of this sort (non 100% yield factor) to be graded and sold to target application markets accordingly, so it's entirely possible that Nikon buys a certain sensor grade with some specified tolerance on acceptable numbers of pixel defects. We just don't know what that number is. </p>
  6. <p>I don't know that there are any technical terms to describe ones observed atmospheric lighting conditions; more appropriately one infers the lighting condition from the observed cloud-type. See:<br> <a href="http://en.wikipedia.org/wiki/List_of_cloud_types">http://en.wikipedia.org/wiki/List_of_cloud_types </a></p>
  7. <p>Amby, here's a rough adjustment that's far from perfect, and makes other flaws such as the reflection in her glasses become more apparent (and harder to fix): </p> <p><img src="http://d6d2h4gfvy8t8.cloudfront.net/17937756-lg.jpg" alt="" width="576" height="572" /></p>
  8. <p>Hi Amby, that's a lovely photo of your daughter and I can see why you'd want to preserve it. </p> <p>It's possible to "fix" the photo in software but will involve some relatively advanced techniques. The steps are roughly as follows:</p> <ol> <li>Select the circular section where the green cast appears (due to lens flare);</li> <li>tweak the selected area by reducing the green channel and bumping up the red and blue channels;</li> <li>adjust the brightness/contrast (using "Curves") to match the selected area with its neighbor;</li> <li>followed by an overall adjustment of color, contrast and brightness.</li> </ol> <p>The most difficult part will be in the selection of the offending area and it will be a challenge to make the fix totally seamless since any flaw will be immediately apparent because it crosses her face.</p> <p>Maybe one of our distinguished members will offer to tweak it for you if you're not up to the challenge as my photoshop skills is rather limited. </p> <p> </p>
  9. <p>Adding to Lex's remarks, Sony calls their Infrared mode "NightShot" that flips its IR filter out of the optical path and uses IR LEDs as an illuminator. It used to be a more common feature on Sony's MiniDV tape based camcorders but is now only available on a select few pricey units:<br> HDR-PJ790V<br> FDR-AX100 4K<br> HDR-CX900/B</p>
  10. <p>My friend's dad had a similar experience; he swears David Hasselhoff met him for lunch but couldn't explain how Hasselhoff gained access through the security access doors into the third floor where he has been living for the last 10 years. :-) </p>
  11. <blockquote> <p><em>"Would you find it strange if your local butcher directs you to the local bakery when you come into his store asking for a loaf of bread?`</em></p> </blockquote> <p>I would shake my head in disbelief if the butcher shop was in ill health, especially if the local bakery he`s sending me to also has a butcher`s counter and sells fresher meat. <br> <br> But that`s not what we have here. <br> <br> The butcher is busy and some of his other apparently loyal customers are redirecting his other customers away, with or without the consent from the butcher. <br> <br> Here`s a screen grab from the 5 year-old bakery you want us to go to, and guess what`s on their butcher counter! And they don`t even have a gallery. <br> <br> I`m already there Off-Topicìng, but my interests is in the law and they happen to have thousands of practicing attorneys answering questions, among countless other professional disciplines. <br> <br> <br> <img src="http://d6d2h4gfvy8t8.cloudfront.net/17935871-lg.jpg" alt="" width="764" height="693" /></p>
  12. <p>Screen grab from the video of the component and its potentially dodgy connection:</p> <p><img src="http://d6d2h4gfvy8t8.cloudfront.net/17935076-lg.jpg" alt="" width="599" height="322" /></p>
  13. <p>Interestingly, this YouTube video suggests there is a common problem with the SB600 on one of its PCBs containing an inductor L301 whose solder joint located close to the board-edge might be dodgy. Might be worth a check:<br /> <a href="
  14. <p>I havent taken my SB600 apart but I have looked at the service manual that shows a rats nest of wires that might potentially cause problems. There is no left-right orientation sensor that I am aware of but there is a head-angle sensor as you flip it from horizontal to vertical. <br> <a href="http://elektrotanya.com/nikon_sb-600-repair-manual.pdf/download.html">http://elektrotanya.com/nikon_sb-600-repair-manual.pdf/download.html</a> - free service manual</p> <p>Let us know if you manage to find the problem, Thomas, and take a few pictures if you can. Most concerning for me is getting the flash back together which can be a real nightmare; you wonder how they managed to put it together at the factory in the first place. I still have a couple of tiny left over springs from a Sony flash I took apart. :-) </p>
  15. <p>Happy New Year everyone! <br> <a href="http://www.huffingtonpost.com/2014/12/27/space-photos-2014_n_6348682.html">http://www.huffingtonpost.com/2014/12/27/space-photos-2014_n_6348682.html</a></p>
  16. <p>Hi Al, Premiere Elements 11 will fill your needs quite nicely if I understood your requirement correctly.<br> <br> You can apply the Ken Burns effect (pan/zoom) to the images as opposed to having them as static on-screen stills which can be quite boring. Here's an Adobe tutorial:<br> <a href="http://helpx.adobe.com/premiere-elements/using/pan-zoom-create-video-like.html">http://helpx.adobe.com/premiere-elements/using/pan-zoom-create-video-like.html</a><br> <a href="http://en.wikipedia.org/wiki/Ken_Burns_effect">http://en.wikipedia.org/wiki/Ken_Burns_effect</a> <br> <br> Syncing the audio using your Zoom H4N can be done in a couple of ways:</p> <ol> <li>you can record the audio separately as you view the images, import it into the editor, then manipulate each photo as instructed above and match it to the audio timeline; or</li> <li>you can record directly to the computer using the H4N as a USB mic. </li> </ol> <p> <br> It's also a good idea to resize your photos approximately to the desired maximum video output resolution before importing them into the editor; say 1920x1080, or larger if you intend on zooming. This will reduce the PC's workload. </p>
  17. <blockquote> <p><em>"However, it's a great place for people from here to go when they want an OT forum."</em></p> </blockquote> <p>Those of us concerned with site health are offering positive input because we don't want to listen to crickets. It's also unwise to make emotion decisions over economic ones; Quora is a good site to gain further insight on that front.</p> <p>None of us <em >need</em> to be here. We <em >choose</em> to be here. </p>
  18. <p>The Off-Topic forum had as many supporters who thought it can be a positive influence on the site as detractors who believe it to be destructive to the main site. Then there are some who believe discussion forums are dead altogether.</p> <p>I believe the Off-Topic forum served as an accurate barometer of site health - the forum's culture accurately reflected the general site culture but became an easy target as the culprit causing site participatory decline which unfortunately was a false attribution. </p> <p>The Off-Topic forum could have served as an experimental platform to embellish site policies by introducing rules, methods, procedures, in isolation to see how it affected forum dynamics. Tweaking it till it works would have meant any insights gained can be transplanted elsewhere to the site's benefit. </p> <p>It's a big problem, but not an insurmountable problem. </p> <p><a href="http://en.wikipedia.org/wiki/Quora">Quora</a> is a Q&A site founded by a couple of ex-Facebook guys 4-1/2 years ago. It now has a few million registered users and a reported valuation of a billion dollars (and growing) manned by about 100 employees, so clearly a high quality, vibrant, and profitable general discussion site can exist if it's well developed and carefully managed. </p> <p>We're probably well past talking about whether the OT forum should (or can) be brought back in its prior incarnation, although I believe it's still possible to do so for the purposes mentioned earlier, but we also can not afford another failed experiment. </p>
  19. <p>Can you show us an example of the failed shot and leave the EXIF data intact? </p>
  20. <p>Wow, what a question! </p> <p>If I ever found myself having to choose between a moral/ethical commitment and a legal contractual obligation, I will breach a contract over a violation of morals or ethics every time. </p> <p>Why? because the loss to the bride/groom in the hypothetical wedding can always be compensated financially or re-staged as a substitute, but a breach of moral or ethical commitment can never be compensated in any other way than the fulfillment of it. </p>
  21. <p>Holiday greetings to everyone and a great coming New Year! </p> <p>For grins, here's a Santa Claus Detector patent:<br> <a href="https://www.google.com/patents/US5523741?dq=santa+claus&hl=en">https://www.google.com/patents/US5523741?dq=santa+claus&hl=en </a></p>
  22. <p>Steven, we have a critique forum where you can ask these questions and others viewing the gallery can comment. Just upload your photos to a folder in your workspace and submit it for ratings and/or critique.</p> <p>I think people generally accept aviation photos at face value since they are typically shot from contained spotting positions where one has little control, so what you see is what you get. Unless, of course, you have authorized access to the airfield and have the freedom to choose your spot. </p>
  23. <blockquote> <p><em>"@Michael Chang - that link just put together the same videos that go round at the internet fueling these discussions and considering it as "well documented" depends on the way you accept them."</em></p> </blockquote> <p>If you read the article and look carefully at the problem, the objection isn't with the existence of flare, but with the dark band above it - the flare is not appearing in a manner as one might expect.<br> <br> It makes no never mind to me because I don't own the camera, but I'd be pretty unhappy if I did. <br> </p>
  24. <p>Appears to be a well documented problem described in more detail here:<br> <a href="http://petapixel.com/2014/12/22/nikon-d750-owners-reporting-dark-band-problem-shows-lens-flares/">http://petapixel.com/2014/12/22/nikon-d750-owners-reporting-dark-band-problem-shows-lens-flares/</a></p>
  25. <p>Hi Nicholas, have you tried that old rubber band trick? </p> <p>Basically you tighten the head just enough to offer some resistance, then instead of gripping the handle to pan, you pull it via a rubber band which will dampen the jerky movement at start and prevent the end-stop backlash.</p> <p>The trick works but at the expense of precision control, though it's simple enough to try. </p>
