Over exposed images from my CANON 5DSR suddenly

[tdehan]

The past few times I've used my 5DSR the images are over exposed.  They are way to bright.  I have the ISO at 50 or 100 and they keep coming out to bright.  This is happening inside with little light so I can't figure out why this is happening.  When I am outside with little light it is even worse.  In order to correct it I have to engage Exposure Compensation.  I've never had to do this before.

Any suggestions or ideas why this is suddenly happening?

[tdehan]

Sure.  However, this has only started to happen recently.  I've never had this issue prior with the black background.

I'm still searching to see what could have changed.

Thanks

What changed? Carefully compare EXIF data.

It is probably because you are processing in Adobe, but I noticed in the EXIF data that it reported the wrong focal length for the lens (105 instead of 180mm)  I was curious if there was an issue and grabbed a file I shot with my 5DS R and EF 180 f3.5, processed through DPP and the EXIF shows the correct lens and focal length identification.

The ISO is reporting as set according to EXIF and you were shooting with the f3.5 wide open so it isn't like you had selected a narrower aperture and have an issue with the aperture blades sticking at the point of exposure.

Set the camera for manual operation with the aperture @ f3.5, shutter at 1/4, and ISO at 100.  Set metering for spot and meter off the center of the blown carnation.  With this setup, does the meter in the camera show it is seriously over exposed?

Yes, the same thing happens.

tdehan,

I expected the image to be the same BUT what did the exposure bar in the camera show?  If it showed a standard exposure with those settings using spot metering on the blown out portion, then it sounds like a problem with the metering system.

Are you noticing over exposure in your RAW images or JPG images? Could it be the Auto Lighting Optimizer setting? Highlight Tone Priority? Or HDR Mode? Could some of these or other settings be ones you were using but they got switched off. Maybe try settings on as well as off which you might have used in the past to see if possibly one inadvertantly switched off might have affected the exposure.

Maybe try recreating a shot you have done previously where you were satisfied the camera was expsoing correctly and see if the problem exists in that setup. Maybe you have done this already...

Just ideas. Good luck.

I only shoot in RAW so only RAW images.  I checked Auto Lighting Optimizer setting which I've never changed or done anything with.  It was set to STANDARD.  I've now disabled it to see if that helps.  Both Hightlight Tone Priority and HDR Mode are disabled already.
