All leaf shutters operate from 1 second to 1/125 (1/100) from the main setting (cocking) spring tension and delay timer mechanism. Above 1/125 a booster spring is employed with the delay timer locked out. Compur shutter use a delay mechanism similar to a watch. With the shutter set to 1 second cock the shutter, position the shutter so you can see the shutter blades and the second hand of a clock or watch (sweep second hand works best). When the second hand reaches a second mark trip the shutter, the shutter should open completely and close just as the second hand reaches the next second mark. The second hand width (narrow style) either side of the next second mark is in tolerance. Set the shutter to 1/2 second and repeat. The shutter should open fully then close just as the second hand reaches the mid point between the starting and next second mark, tolerance is 1/2 the width of the second hand. Increase the shutter speed to the next speed and verify it runs faster as you go up in speed, slower as you decrease the speed. If these two speeds are off all others will likely be also. Buried in the archives of this site are the instructions for building a shutter speed tester, inexpensive and accurate.

The self timer on that vintage are problematic and usually cause the shutter to hang and have to be forced to run down so that the shutter can be used. When it hangs press the release lever then push the cocking lever toward the fully released/home position until the full travel of the lever has been reached.

Likely the self timer lever as shown on the CN-1307-000 Earlier versions are very similar.

Time to do some basic computer maintenance. Clean Mac Malware and Speed Up Mac - Download MacBooster 6 is a paid maintenance utility, its Windows counterpart is reliable, improves computer performance, and does no harm. Mac may have some built in utilities as well. All computers regardless of operating system need routine maintenance. After the basic utility repair/reinstall Lightroom followed by software updates needed for the D810. Its possible that the installation became corrupt during the update. Preferences should be looked at after the installation is verified to be good.

1. Have the camera checked, the shutter may not be working correctly ever time resulting in no exposure when there should be one. 2. Contrast is the difference between tones/colors in a scene. In B&W contrast is controlled by exposure and development. Color print films are developed for a specified time therefore contrast is controlled by primarily by exposure. Exposure is controlled by metering. Learning to meter takes practice. Meters are calibrated to read whatever tone/color they are pointed to as 18% Gray. 18% gray is considered mid tone. Matrix metering averages the tones to 18% gray. If you point the meter toward a white object the suggested exposure will make the white look gray/dull white in the print. If you point the meter at a black object the meter will make the object mid gray or washed out black in the print.

Don't expect Epson to tell you how to get the most out of your scanner, expect them to assist if the scanner does not work. Epsonscan is the same for V500, V550, V600, V700, V800. I run the first and 4th of these. First off set the software to Professional Mode Next click on the Configuration tab click on the No Color Correction, close the box, and scan the negative, edit in post processing for the best looking image. The histogram adjustments will be negated if the Continuous Auto Exposure is not deselected with Color Control selected. Information in the negative will be the vertical rise above the base line. The White triangle is the highlights, the black one the blacks, the grey one the gamma or mid tones. Set each the black and white to the point where the information for the darkest black and brightest white start to rise above the baseline, then slide the grey one to give the desired mid tones, toward white darkens, toward black lightens, very slight movement is needed or necessary.

Hard for me to say what the exact cause is but the common ones are residue from cleaning or the materials gassing out and collecting on the inner surfaces. If its gassing out it will build up into a light to medium haze. I would start by cleaning the outer surfaces with a clean heavyweight microfiber lens cleaning cloth and my breath. Light weight lens cleaning cloths are worthless as are eyeglass cleaning cloths when it comes to camera lens. After cleaning the external surfaces consider having the lens serviced if they remain especially if they affect image quality.
