  1. <p>It could be the three pads under the mirror, which is not an easy thing to solve and it is normally not included in a CLA. Check with David about this repair.<br> You might check by repeating the test with the camera upside down and sideways. If the pads are gone, the mirror will move inside its frame.<br> <br />On a final note, do not expect "pixel" or "grain" perfect focus at large apertures with an over 30 years old device. For that you will need a recent digital back capable of live view.</p>
  2. <p>The out of gamut warning tool in photoshop is not accurate. It is not intended for this type of test</p>
  3. <p>There is a chance the problem is due to the lab. Some of them start to unroll the paper back with the lights on to reach the beggining of the film (it has happened to me many times). Try to advance a little bit further than the arrows aligment when you load the film and note if the burnt area changes accordingly</p>
  4. <p>No, editint DNGs in Lightroom will give you the same quality as editing from NEF</p>
  5. <p>In addition to what the previous posters said:</p> <p>The main difference between the "silver" and "black" old "C" lenses is that the blacks are multicoated, which may give you more contrast and better resistance to flare. There might be very few lenses that does not follow this pattern, so look for T* (in red) which identify the multicoating.<br> <br />I second the advise about David Odess. It will cost you more but you will enjoy the experience. These cameras are around 40 years old by now and lubricans may have lost their properties and some parts may need replacement beyond the obvious light traps of the back. One example is the rubber piece (the name might not be accurate) that goes around the frame that supports the focusing screen, that absorbs the impact when the mirror rises: this deteriorates with time and it should be replace.<br> <br />If you are looking for critical focusing with the lens wide open: Get the new series with the gliding mirror. The old mirror sits on top of three cushions that also deteriorate which are difficult / expensive to replace. The new system is much better (They are more expensive of course).<br> <br />For the record, I have a 500C/M, 500EL/M with black C lenses.</p>
  6. <p>The AF-S Micro 105 on a digital nikon body will compensate the aperture at close range to keep constant the "effective aperture". This means that when you are close to maximum magnification the aperture mechanism will move while changing focusing.</p>
  7. <p>I would recommend leaving it to a professional, unless "mechanically savvy" means someone trained in lens repair.<br> BTW, I had the same issue with a 50mm f1.4 AIS, and after service it was like new.</p>
  8. <p>One possible cause is a temporary bad connection between the lens and the camera due to humidity, movement or dust. When this happens, the lens will be closed to the minimum aperture (Nikon behaviour) and the resulting image would be very dark, almost black.</p> <p>It is not a common issue, but it happens once in a while. The first thing to check in detail is the EXIF for those black images lookign for minimum or missing aperture values. If you have non-CPU lenses defined in your camera, it will use the values of the last used non-CPU lens to write the EXIF.</p> <p>Since you mention the action was "Fast and Furious", there is a chance that movement between camera and lens produced the issue, even if it was inside the tolerance of the mechanical lock</p>
  9. Make sure you are using process version 2012 in the camera calibration panel
  10. <blockquote> <p>But I remember the color correction filters I used to use in bright sunlight, light overcast, to shade with Daylight Kodachrome. Those allowed me to tweak the results in camera so the image would be correct. My filter did the trick</p> </blockquote> <p>Trying to match different digital cameras would be like using in the film days Fuji Velvia, Kodachrome and Kodak Portra and pretending matching results</p>
  11. <p>You can do it with ACR/Bridge if you wanted without any issue. Recent versions of ACR allow you to use a database to store the adjustments instead of creating xmp files. Just go to camera raw preferences and select "Save image settings in: Camera Raw Database"<br> I just tried for fun with 700 images from a D800, all at once, and the adjustment took only seconds, while the update of the previews took a few minutes.<br> <br />Bridge, ACR, LR and even Capture 1 use the same database SQLite, (Yes, part of the Bridge Cache is a SQLite database) and 900 is a really low number of transactions for a database.</p> <p>LR is perhaps the most ambitious implementation that I know for SQLite in terms of the schema (tables and fields) and its main difference with other programs is the library implementation, not the database itself, because almost any other program use a database too.<br> <br />One comment about copying white balance in LR: If you copy the settings from an image where the WB is "As shoot", then it will copy "As shoot" and not the temperature / tint values. Maybe this is obvious to everybody else but it was not obvious to me.</p>
  12. <p>In addition to what Andrew Rodney said, if you only want to display your images (library, slide show) for keywording, rating, slideshow, etc, you just need the standard previews<br> <br />Another big advantage of LR (for me) is that the logical organization of images through collections is independent of the physical organization (drives and folders) and you can have an image in more than one collections. E.G. I can have a collection for red cars and other for european cars. In a folder structure I have to choose either red cars or european cars or have duplicate of the images.<br> <br />Most complaints I read in online forums are from users that want to use LR as a browser. Well, it is not, so if you can't stand the import process and preview creation, then keep using Bridge, which is a fine tool too.</p>
  13. <blockquote> <p>Is Bridge multi-user?</p> </blockquote> <p>Bridge is just a browser so you might have more than one user accessing a folder. Also once you complete your work on an image, it is available to any other user without having to export first</p>
