E-M1.2 overexposing by about one stop.

I went into a 'dim' loft put my camera to my eye and and through the EVF I thought someone had switched the lights on.

Took my camera from my eye, no the lights were off.

The EVF and exposure appear to be off by about + one stop.

Am I missing something?

ISO is on Auto, is there any way to dial in minus one stop permanently, apart from the front dial for every shot.

Never had this before with either M5, M1.1 or M5.2 usually ambient lighting is whats seen through the EVF.

Re: E-M1.2 overexposing by about one stop.

Is it just the display, or are exposed photos also over-exposed? If it's just the display it could be that you have got the Live View Boost option switched on. This brightens the viewfinder in dark conditions, which helps with composition but does not help judge the exposure. I can't remember where it is in the menus, but if you search the manual you should find it easily enough.

It caught me out once because a default changed from Off to On with a firmware upgrade. I shot half a gig setting exposure by eye before I twigged what was wrong!

Re: E-M1.2 overexposing by about one stop.

Try looking down in "Cog J"

Brightness is automatically adjusted when [EVF Auto
Luminance] is set to [On]

There is also the Simulated OVF that you can try

Turn on over/under exposure blinkies - it's clear then what's over/under exposed.

Sorry, but that would be under Menu I for EVF Adjust, EVF Auto Luminance: ON or OFF.

Re: E-M1.2 overexposing by about one stop.

Seems to make no difference on or off, nor does Sim OVF.

And it's over exposing by one stop.

To my eye the first looks under-exposed and the second looks just right.

The first shot is how the garage ambient lighting actually looked, the second shot is how the camera interpreted it.

I've always felt that my E-M5, E-M1 & E-M1 Mk II (& Stylus 1) has always exposed longer in those dark situations bringing up the details more than reality, but I just count that as an advantage & if darker is wanted then exposure compensation can be used.

There's no such thing as "correct exposure". The meter will not do that for you. It's part of the job as a photographer to get it right and convey what you want to convey. The exposure meter is a starting point - no more. Sending your shots to Olympus will not yield any useful insight IMHO.

Personally, I'd recommend that you:

- Shoot raw
- Turn on over/exposure blinkies
- Avoid blown highlights
- Tweak in PP to suit how you want the scene to "look"

Re: E-M1.2 overexposing by about one stop.

I did some test today, prompted by this thread, using a Sekonic meter.

Setting the camera to the readings from the meter, was only slightly different to the settings that the centre weighted exposure provided. However, as I expected, using a grey card and spot metering gave readings very close to the Sekonic readings.

Surprisingly, the iAuto did very well.

You don't say what metering mode you were using - spot , centre weighted or whole frame?

Makes a huge difference to the exposure if you were using spot and focussed on a bright part of the scene.

Re: E-M1.2 overexposing by about one stop.

To my eyes the second one looks correctly exposed inasmuch as the camera has rendered the highlights and shadows properly. If you want a low key look to the image then you need to use some exposure compensation. What Paul said, really.

Re: E-M1.2 overexposing by about one stop.

Oooooooo....Exasperated.

Everybody it seems, everybody, is misinterpreting the essence of this thread.

I know about exposures, how to manage them, how to manipulate them in camera to achieve the desired result....we're talking JPEG here.

I could and do shoot JPEG+RAW....RAW would solve the image exposure problem but not the EVF and Live View over exposure.

Even with a cardboard camera from Boots, when one looks through the viewfinder at a scene, one sees what's on the other side of the lens.
The resulting captured image is, more or less, the same.

If I look through 'any' view finder I expect to see and capture what's on the other side.

My GRIPE is that with my 2k technical wizard I do not, I see and capture something different.

I've fiddled with menu settings, EVF adjust and LV Boost etc and those suggested by Oly, nothing works.

I've had many OMD bodies and none have behaved like this one.

WISIWIG is what I love about M4/3 but it's not happening.

Now the problem has been batted back to Oly....watch this space.

Re: E-M1.2 overexposing by about one stop.

I still don't understand what you think is wrong.
1. Do you think the camera is exposing the photos incorrectly? The title of the thread says it is overexposing by a stop, but I have not seen any evidence for this. The photo in the dark room looks about right to me.

2. Now you seem to be saying the problem is in what the EVF displays. There are various settings that control this. With my camera set to the normal defaults, in A mode, if I adjust the exposure compensation I see the EVF getting lighter or darker. Do you see this? Isn't this what you want?

3. You say about the room "this is how it actually looked". I'm not sure what that means, as your eyes adjust according the light they receive, just like the camera. If you were including the bright areas in your view of the room, yes it would look dark. If you shaded your eyes so you only saw the dark areas, after a few minutes your eyes adjust and it will look brighter. I'm wondering if the issue is more to do with your eyes in these difficult lighting conditions, than it is about the camera.
