Does the camera have film in it, or is the light grey area at back of the mirror box not the usual black film pressure plate? Alan

Sorry I have only come to this thread late - have you all ruled out issues with the lens/filter? (Especially issues in the centre if the affected photos are from heavily stopped down apertures) Reg ...

Doing a bit more online reading, it does seem there are variable reports about the effect of these CT hand luggage scanners on film. Some reports suggest you get bad fogging, some that you only ...

It does seem Amsterdam has started to introduce the new scanners: https://thepointsguy.co.uk/news/ams-ct-scanners/ I suppose another clue to the type of scanner you are using as mentioned in that ...

Hi - presumably you just went through an old style scanner in a rectangular sort of box? The issue for film as mentioned earlier is the new CT scanners that are being introduced which are a bit ...

So why do you say the noise doesn't exist given "noise" is just a synonym for the variation? Alan

No-one is saying that it isn't a statistical construct. But that doesn't mean that there isn't an actual random variation in something in reality. Alan

I don't think they are conceptually wrong. First you need to be careful by what you mean by "signal" and "noise" here because you have an array of pixels - by "strong signal" do you mean an ...

There is no rule that noise is only something that is added by something (like by the electronics). It just means there is some random variation on top of something you are interested in, so there ...

As you may now have realised, if you have uniform illumination falling on a sensor, the number of photons which hits each pixel will differ from pixel to pixel because light is made up of photons. ...

I don't know about Germany but the main issue for ordinary speed film is the type of scanner in use - the older type which is OK for ordinary speed film, or the newer CT (3D) type scanners which ...

Isn't some of it caused by the rapid increase in the number of YouTube videos about some cameras? When I bought a Nikon FE about 6 years ago there only seemed to be a small number of videos about ...

They are just metal blades that overlap. Whether there is a slight light leak or not is hard to tell without running a film through the camera. I suppose you could investigate whether there is a ...

I don't see why you can't push it down if you are careful. It's designed to be pushed down to some end position. (Probably 6 o'clock,) The timer is like a clockwork toy. When you push the lever ...

In your photo the timer is pointing to about 8 o'clock. When you press the shutter button it should rotate clockwise to point upwards to about 12 o'clock at which point it takes the photo. So to ...

I am not familiar with this exact camera model, so there may be some trick to unjam it. But in general in a film camera, the film advance lever/shutter mechanism stores energy which is what ...

You do not want it in B mode. That holds the shutter open for as long you hold the shutter button down. Just put it in one of the shutter speeds like 1/125 s. You should only have to press and ...

The mirrors are presumably different sizes in FF versus cropped bodies, and there may be very slight variations in the mirror sizes anyway from model to model (I think there are in Canon cameras). ...

If you look at the manual for this camera: https://cameramanuals.org/olympus_pdf/olympus_pen_em.pdf you'll see that the battery arrangement is a bit strange. The batteries go in the same way around ...

Do you need a needle for some particular  reason? - Just the plastic syringe body on it's own will suck up and hold liquid. Alan
