preview – Since Picture Profiles don’t apply to RAW, why do they affect the viewfinder?

Sony S-log picture profiles trigger ISO override and compensate for the resulting lower raw data values by applying a suitable tone (gamma) curve.

When the camera is set to ISO 3200 the actual taking ISO is around 400 (you can see that in the Makernotes, at least for the raw files). Here is an example:

EXIF ISO                             : 3200
MakerNotes Sony ISO                  : 384
MakerNotes Stops Above Base ISO      : 1.9

Here the actual taking ISO setting is 384, 3+ stops lower than the one that was set on the camera. Leaves plenty of room for highlights, midpoint in this case is below 2% instead of the usual ≈12.6%

You can take a shot of a gray card and analyze the raw data to be sure of the midpoint offset.

troubleshooting – Why is my Nikon D3300 taking almost totally black pictures through the viewfinder but is fine on liveview?

Looks like the mirror may not be swinging out of the way correctly when the shutter fires. Try this :

Put the camera on viewfinder mode, put it to your eye and take a picture. The viewfinder image should go dark for a fraction of a second as the mirror swings out of the way and returns.

If it does, there could still be an issue with the synchronisation between the mirror and the shutter. Try a really long shutter time, say 1 second. If the mirror swing is just slightly delayed, you’ll probably get an image this time as the mirror gets out of the way part way through the exposure. If it’s gone really bonkers, the mirror might not move until the shutter closes, in which case the viewfinder won’t go dark until after the exposure is complete.

camera – Why does my eye lose white balance and feel exhausted when I use my viewfinder?

My D80 has a greenish tint effect (shutter count at approx 46000) in it’s viewfinder which goes away if i use it long enough constantly looking through the viewfinder.

The weird thing is my other eye starts to see things in green tint when i use it for viewfinder instead.

I don’t keep my both eyes during shooting (neither when it comes to shooting certain devices) for easier manual focus but this was a interesting effect.

The other thing i find weird is that my left eye feels exhausted if i keep both of my eyes open.

So, is this normal? What are these called.

Looking through viewfinder I see subject in small circle instead of large rectangle

You can take the lens off and look through the viewfinder without a lens attached, if the problem still exists, then it’s the body. If not, it’s the lens. Nothing will be in focus, but you should have a full very of light without a lens attach.

Look through the front of the lens and make sure the aperture is open all the way, it’s possible it’s stuck or they didn’t put everything back together correctly. It should be open by default. If it’s stopped down even after the camera is turned on, then the lens is broken, or your contacts between the lens and the body aren’t functioning correctly.

Most likely an element got knocked loose during shipping.

What’s the point in covering the viewfinder?

Recently, I found out that the rubber cover on the strap of my Canon EOS camera is used to cover the viewfinder. I searched on the web to learn why should I cover the viewfinder and I read that it prevents light passing through the viewfinder and somehow getting to the sensor.

  • Is this true?
  • If it is, how does light get to the sensor? Doesn’t the mirror prevent that?

canon – Auto focus won’t work in viewfinder on Aperture priority mode

My camera (Canon Rebel t7i) won’t auto focus in manual or aperture priority mode in viewfinder. (It works perfectly in liveview)

Maybe it’s important to say that I’ve never shot in manual mode so I wanted to learn how to shoot in Aperture Priority mode. Auto focus isn’t working in viewfinder though. I used 2 different lenses (canon 50 mm 1.8 and the kit lens) It doesn’t work on both. I tried resetting the camera. Still nothing.

It does work in auto mode in the viewfinder.

Am I doing something wrong or is something broken?

film – How do I go about fixing this strange dark line blocking my Minolta XG-1’s viewfinder?

I recently bought my friend’s Minolta XG-1 which looks super well maintained cosmetically. He did mention to me that it was sitting in his hot attic for about a year.

I noticed that there is a weird black line covering about 25% of the viewfinder. It has a weird bubbly texture and I suspect it has to do with something on the prism itself.
I tried cleaning and thoroughly inspecting the mirror and the focusing screen (I am new to photography so I am not sure but I think that’s what the thing above the mirror is called) and found nothing suspicious. There is barely a single speck of dust left after cleaning everything.

Additionally, the weird line in the viewfinder is still present if I look through it without a lens attached.

What steps could I take to attempt to clean this out?

This is a picture of what I see through the viewfinder:

Hasselblad H cameras. How does the viewfinder image correspondent with the photograph?

The Hasselblad H cameras are modular. There are different digital backs for each camera available which actually feature different sensor sizes.

How does the image in the viewfinder correspondent to the image that the sensor will take? With different sensor sizes the image wont be the same.

My Nikon fullframe DSLR masks the viewfinder when it is set to APS-C mode so I know what the image will look like. How does a Hasselblad H cameras viewfinder show me what image Im about to take?
