A few days ago, the images of a website that I maintain have ceased to be displayed in Gmail. The Google Image Cache proxy returns 404 on each image. I can confirm that they are accessible on the server itself and that the information letter is displayed correctly outside gmail.com, even in Gmail's own mobile application 39; apparently does not use Google Image Proxy). I can even confirm that Google's robot regularly extracts these images from the server itself, the latter responding to the state 200 and sending the image. The images in question are png and jpg, no svgs (which seem to have had problems in the past according to my research)
Is there a known cure for this and why is Google this bad? Is there a special header that should be defined for this? Do you like the Cache-Control headers required by their image proxy?
The Nikon FG-20 is equipped with an electronic shutter that will not work properly if no battery is inserted.
You can, with limited capabilities, continue to use the camera without battery. The brightness measurements will not work, of course, but the shutter speeds are also limited to B and a 1/90 mechanical controller indicated by "M90" on the speed dial. Unfortunately, if no battery is inserted, the camera will use 1 / 90s shutter speed if the dial is set to something other than B, so you have probably exposed all your images at a shutter speed 1 / 90s and not the one you have set. at. If this is still within the exposure range of the movie you have used, there is still a good chance that you can get the correct prints from the movie.
This is in my humble opinion a strange flaw in the user designs and otherwise quite significant operations presented by Nikon. This would have been much more logical if the shutter did not fire if the abbreviated number was set to an "illegal" value. I made exactly the same mistake when I had my FG-20 and wanted to check if the camera was working before getting a battery. I first thought that the shutter was broken because most of the images of the first movies were poorly exposed, but then I realized that the camera needed to A battery for the speed settings to work. Since the FG-20's shutter is relatively quiet, it is also difficult to hear the errors, since all shutter speeds greater than 1/60 s have a more or less identical sound. On many other devices, the shutter sounds differently at different speeds and such an audible feedback can actually be very helpful in confirming that the camera is doing what you want.
There really are not enough elements in your question for anything more than a shot in the dark. In the future, and even for this question, change it to explain which camera and which lens you are using, what settings are selected, what troubleshooting you have attempted, if you have hit / damaged / lost the camera. camera to a friend / anything that could have caused physical damage …
Missing all of this, please:
Turn off the camera and remove the battery
Replace the battery and turn on the camera, make sure that a lens is attached
Make sure the autofocus switch of the lens is set to AF
Turn on all the lights in the house / room or go out during the day. Make sure there is a lot of light.
Set your camera's settings to:
AF Mode: AI Servo
Shooting mode: manual (M)
Autofocus point selected: Center
Now, try to focus on something. Does the camera try to get the focus? If so, move on. Has the camera tried to get the focus? Well.
Now, take the shot. Your camera will have captured an image that, due to the fact that you do not set the shooting settings, is probably undesirable. That's not the point here – he captured a shot.
Now let's start by going back to your usual settings. Set the AF mode to One Shot. Repeat this exercise. Did you have a shot? Awesome!
Finally, restore the shooting mode on what you normally use (TV, Av, Sport mode, whatever). Repeat the exercise. Did you have a shot? Sounds good?
If your camera has not managed to get the results of any of the above tests, change your question to explain the test you tried, its behavior and what it was about. did not (attempt to focus, capture impossible).
In autofocus mode, my camera will not focus. The lens will make the twisting movement, enter and will not be in focus and will then stay out of focus. Then he will not even take a picture. In addition, when manual focus is on, a picture is taken, even though the picture is black. The mirrors look good. When I use the screen lever to display the photo I'm about to take, this one is also black, although I can see a thin line down at the top of the screen. where the picture passes.
