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,

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.

What happens if you shoot outdoors?

EXIF data indicates you used matrix metering. The black background is a significant part of the image and the exposure system is targeted to an overall middle gray.

The histogram for the image you posted looks like this:

The spike is driven by the black background.

But since the cmaera wants to see middle gray I suspect your out of camera histogram/image looks sort of like this:

Negative 2 or so exposure compensation to make middle gray black is not unusual.

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.

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.
