You appear to be using your lens (100-400/5-6.3) with the aperture wide open. I would expect the glow in your photos to be significantly reduced or absent stopped down to about F8. Many lenses "glow" when used wide open, especially in bright light with high contrast. It is likely associated with spherical aberration and is typically reduced or completely ...

The fact you're seeing this with two very different bodies suggests to me it's in the lens. Long zooms tend to have a bunch of elements (anywhere from a dozen to twenty, in my experience). No lens coating is perfect, and no lens surface is perfect. Every time light passes through an air-glass or glass-glass interface at an element surface, there's a small ...

Are the frame numbers visible? If they are, processing chemicals and times are fine, but the film was not exposed. If the frame numbers are not visible, whether or not the film was exposed, the processing is at fault - exhausted chemicals or maybe incorrect sequence.

In a nutshell1 AGPS (Assisted/Augmented GPS) is a method to help a GPS device determine the position of the GPS satellites by supplying pre-computed data. The data itself changes in time due to the fact that the satellites themselves change in position over time in a manner that can't be expressed by a simple formula directly implemented by the GPS device ...

Assuming this was B&W or color negative film, the most likely cause of completely clear film (no edge markings, no exposed leader for 35 mm) is mixing up the graduates and pouring the fixer before the developer. It's an easy mistake to make, even (especially) after processing hundreds or thousands of tanks previously. All it takes is an interruption or ...

Not on screen but, I have a D7000 and serial number for that camera is in the EXIF data of each image it takes. GIMP can view/edit metadata. For my D7000 camera... Open JPG/RAW image in GIMP Menu --> Image/Metadata/View Metadata Select "Exif" tab at top Look in "Exif Tag" column Scroll down and look for "Exif.Nikon3.SerialNumber" The number in the "Value" ...

The biggest problem with repairing Nikon lenses yourself is that Nikon no longer sells replacement parts to anyone outsides Nikon's authorized service network, including third party repair shops. To make matters worse, as of March 31, 2020, Nikon is not renewing agreements with any current Nikon authorized outside repair shops that are not owned by Nikon. ...

You've got a dirty lens. First, alcohol. IPA, ethanol. Use that with a microfibre cloth. That should dissolve the oils, but you want the cloth to pull it off of the glass and into the cloth. Don't reuse sections of the cloth. Then, a little Deionized water and soap- a tiny tiny tiny smidgen. Again, just enough to be a surfactant. Wipe the lense elements ...

I can't help you with disassembling that lens but since that lens will focus beyond infinity, I would either buy, or print yourself, a thin M42 to Nikon F adapter. You can buy one like this for under $5.00

In my experience, extension tubes for Nikon (compatible with D70-D90 generation cameras and their lenses, at the least) are quite inexpensive, in the range from $30 to $100 for a set of three (three different lengths, can be combined in any combination). This is because there are no optics in the tubes, just carry-through for the electronic contacts and ...

This file contain orbits of GPS satellites (simplified). This information is required to calculate the satellites position and with precise time received from satellites to calculate your geographic coordinates. And it is indeed limited to one week data. If you do not update this file you need to switch on you camera and stay in open space with good ...

All lenses are debased by aberrations, two of which deal with color. The lens maker endeavors to mitigate by crafting the lens using multiple lens elements. Most commonly, chromatic aberration displays images with a rainbow colored edge effect. This is caused by the fact that each color has a slightly different focal length. The violet image falls closer to ...

I just did the same, using my SB700 (and D850)with the Godox X pro N and the X 1 receivers. It worked great practicing in the house, either on Manual or TTL (on the flashes), but when I tried to set up a quick shot today, the flashes won't flash when on remote mode. I did not remember changing anything after intially finding that the set up was very simple ...

There is a very nice tool to remove JPEG artifacts and get DNG file out of pixels. Sure, it can't reconstruct HDR and other details, but still it may be helpful. The application uses machine learning (convolutional neural networks) to process input image (e.g. remove compression artifacts and slightly remove noise) and don't make it blurry as using just ...

It's simple to do in camera: Select picture. Press OK, this brings up the retouch menu. Press OK to trim. Adjust size with +/- buttons and maneuver into position using the multi selector button (around the OK button). Then press OK again. You're done Alternatively - pages 330/331 D3200 for Dummies.

I had this problem and I believe it is because of being too close to my subject for the lens I had on and so the camera was unable to autofocus. Even if I tried to focus manually, I was too close to get in focus. Moving back a bit allowed the autofocus to work fine. Or, as was suggested, I could turn off autofocus on the camera and/or on the lens and even ...
