I am a professional shooter and have been using a couple of A1 cameras for 2 years after 38 years with Nikon and Canon. For 38 years, I relied on my lightmeter all day, everyday, but since going mirrorless, I rarely (actually never) look at the meter. I change my variables until the scene looks the way I want it to, and press the button. Perfect. Except..... I have always said that the beauty of mirrorless is that there is no need to chimp your photos after you take them, because you have already chimped them before you press the button. Most of the time that is correct, but I find that when I'm shooting in really low light, especially with a nice subtle colour in the sky and also especially if the subject is silhoetted against that sky, there is a problem when I download the images. The images in this case are 3 to 5 stops underexposed. To the point, that there is no way I would have taken the picture if it had've looked that dark through the viewfinder.
I have spoken with my Sony rep at length about this, and we are both stumped. And no, I am not activating Bright Monitoring.
This only happens a couple of times a year. otherwise I would get into the habit of chimping very shot taken like this.
Has anybody had the same issue?

In the attached image, the top of the Memorial Cross was plainly visible in the viewfinder.

Hi did you shoot with live view on? if so that will be the issue more than likely. You should turn it off in low light.
 
Bear in mind on play back you see a jpg extract from the Raw file and not the Raw image if indeed you are shooting in Raw.

I mentioned in my post that I didn't chimp (or playback) after taking the picture because I am so used to not needing to. In every other situation, it is what you see is what you get before you take the picture.
 
WYSIWYG is what we demand when looking through the viewfinder of a mirrorless camera. When I first used one, I was amazed at how “sparkly” things were, but those are pixels shining back at me. It’s possible that there is a perceived difference between a pixel representing black, and a pixel representing almost black, that isn’t displayed that way on a high resolution monitor. The resolution and colour depth of the viewfinder - does it actually match the sensor? Does that match your monitor? When I look through the viewfinder now, I don’t see sparkles anymore but I wonder if the viewfinder just shows me what Sony wants me to see? Is that sharpness an AI feature? Etc.

That was a yes. I’ve also noticed the resulting image in raw or heif, darker than I saw through the viewfinder

I don't have the A1, but the same applies on the RiV. Viewfinder images are inherently brighter, and while I love that I can see changes made to settings as I make them, I don't rely on it for genuine exposure. I do tend to shoot over exposed (see Brownies thread) as it's easier to correct in post, but the RiV RAW images are extremely malleable too, which helps. Underexposure certainly creates more noise though (more than high ISO)

I do not want to state the obvious but as a pro it should be second nature to look at the numbers and exposure triangle in the viewfinder and the answer is in front of you regardless of what you see in the viewfinder, and all manufacturers provide ev dial for a good reason, we are all guilty of assuming the tech is better than experience pro, or a hobby shooter like most on here including myself
 
I have this experience I think. I have been shooting for my church for nearly 10 years. This involves a band on stage in low light with stage lights that would typically fool a light meter. I have always shot in full manual mode and check my photos for exposure using the back of the camera. Using Sony mirrorless I have been using the EVF / monitor as a guide to judge exposure and have been underexposing by 1-2 stops. This hasn't bothered me as I can easily lift the exposure in post. More recently I thought I would try auto ISO and just see how it copes. On the monitor it looks like I am over exposing and clipping highlights on faces but when I get back to my computer the photos have been exposed perfectly. The meter has not been fooled by the stage lights which have been clipped as required. I should have known it would intelligently expose for faces but have never adjusted from my DSLR days until recently. The dynamic range latitude has covered up my bad habits.

Happens to me too. But I don't have a solution except chimp the first few you shoot off, then check the numbers and set manually - on the plus side, the range with RAW is big enough to make an image I find

Turn off „dynamic range optimizer“.
it applies to your JPEGs, and by that it also applies to the EVF.

Hi, interesting. So do you mean that the image displayed in the EVF is a JPG regardless of shooting mode ? So if I shoot Raw only the image displayed in EVF will be a jpg ? This would make sense but never thought of it.

Yes, indeed. Lots of people have your issue when they start out with Sony. I shot 2 stops underexposed for like a year myself. 😬
 
Going back to original question !!! As posted before refer to Sony manual, turn off live view in dark conditions, how do you suppose what you see with the naked eye looks dark, but when viewed through the evf it suddenly looks bright, its not magic its common sense with live view off once again what you see is what you get simple, the view through the evf will be so dark you will have to adjust the settings in manual, basic stuff. a link here one of many on here there are more by others with the same conclusion https://www.alphashooters.com/commu...ight-only-and-return-to-ship-via-tender.5184/

Ok so yes the image you see on the rear of the screen or evf even if shooting raw is an image similar to that of a edited in camera jpeg, hence the difference when you load raw files to your editing software

Found this thread which really interests me. I fee like my A1 underexposes compared to my other Sony cameras. Found this comment:
The A1's matrix metering system tends to underexpose subjects against bright backgrounds ( from here)
See the image below, histogram looked great, EVF looked great, but looking at resulting JPEG I feel like its underexposed. I'm planning on printing this one and will go back to the RAW and lift the exposure. Appreciate thoughts

I am suprised you have not noticed this on other Sony cameras Roger, I am always playing with ev and am sure most of the other experienced Sony shoots on here do the same :)

I really only noticed it on the A1, going to really play with EVF settings, and recalibrate my monitor I use for image processing.

I see it on the A7 IV and A7R III.

FWIW, that image looks perfect on my screen. Any brighter and it'd be harsh.

People are predisposed to bright images.

Exposure looks completely fine to me, what’s wrong?

The raw will have all the information from all areas, so you can adjust it any way you like.
 
I've now looked at that image on four separate screens and there's not a thing wrong with it. I suggest you check your monitor calibration.

I did not think that it looked bad I assumed it was more of a general problem that Roger had just noticed across multiple images

Turn off Live view in low light. That should help.
 
Townie I just had this issue! Two shoots, 4 stops underexposed but worse, the LCD showed them well done and the meta numbers showed them well exposed. In post I could bring them up those 4 stops. I have been shooting film for two months again so I called my friend Lloyd Chambers of Diglloyd.com. We thought it was pilot error. Next shoot I was super careful but it happened again. Neither of us could figure it out. Then two days ago we spent hours on the phone with the camera and through the process of elimination we solved it!

In Video, I use PP10 or PP11. In Camera shoot manual mode but ... PP10 was on somehow. That is S-Log 3. It is meant to be edited and color corrected by video software. It may have been my setting the camera up for video a few months ago and forgetting to get out of PP10 for stills. I know what happened but not why the camera does this. It is an apparent bug in Sony.

Solution: go to COLOR in the shooting menu, and when in CAMERA turn OFF any PP. I don't even use PP2 any more. Just OFF. Now it immediately acts like it should. ALL is well. Hope this helps.

Townie/Butch ... If you check that you have separated the settings for Stills and Movies I think that might eliminate the issue. Additionally, keep DRO off as others have said.

Search the manual for "Different Set for Still/Mv" and separate the settings.

That will stop the PP from Movies interfering with your Stills.

Hope that helps.

Presume this only applies to the A1 and A9111 . As others have said this is a common accurance on most sony cameras ,my A9II does it, looking in the Evf its fine then when you download to computer it's like somebody has turned the lights off .
