jacopastorius Posted July 28 Share #1 Posted July 28 Advertisement (gone after registration) Hi all. I got my M10 for 3 weeks and used it only in manual mode. Today I tried aperture priority and auto iso mode. when I am in aperture priority and rotate the thumb wheel to compensate the exposure I noticed that the speed values are changing. The same is when I am in auto iso. honestly I am not a huge fan of exposure compensation and never used it with my previous cameras. But shouldn't it be supposed to just change the brightness keeping the speed and iso as I set them? Link to post Share on other sites More sharing options...

No. Ask yourself how the camera achieves "brightness": Either by adjusting the aperture by adjusting the ISO, or adjusting the exposure time (which is on "A"). There is no fourth option. Adjusting the aperture is not possible (since it is fully manual) Adjusting the ISO is not possible in fixed ISO. In Auto ISO it would be possible, but it is less commonly used (this is probably a convention that dates back to film days but I don't know any manufacturer who translates exposure compensation to ISO change unless the dialed low speed limit is reached). So adjusting the exposure time is the only (and common) way to execute exposure compensation. In manual mode however, the exposure compensation just affects the readout of the meter - so it allows you to choose whether to use aperture, time or ISO to compensate.

So what's the point of using the exposure compensation? it is the same of going one stop up or down changing the speed Link to post Share on other sites More sharing options...

So what's the point of using the exposure compensation? it is the same of going one stop up or down changing the speed yes 😝 When you shoot in Auto (assuming a landscape with the bottom part the land and the upper part the sky) then you can easily move the camera a bit up or down and look at the shutter speed. Then you can easily choose one (half press the release button and tehn reframe your image) that will result in a darker or a lighter image. 1 Link to post Share on other sites More sharing options...
Chris W Posted July 28 Share #5 Posted July 28 2 hours ago, jacopastorius said: But shouldn't it be supposed to just change the brightness keeping the speed and iso as I set them? But you chose aperture priority. So the camera is keeping the aperture you chose and changing the shutter speed. If you chose shutter priority it would change the aperture in 'compensation'. With a bright sky I tend to shoot with exposure compensation so my main subject isn't too dark, or you could just go complete manual and adjust the aperture or speed to over expose a little (the bright elements), so your dark shadows aren't too dark.

jgeenen Posted July 28 Share #8 Posted July 28 (edited) For me, it all depends on personal preferences and shooting situation. On landscape photography I usually go with manual mode and slightly adjust the exposure balance to compensate for highlights or shadows. Why? Because the average lighting doesn't change too much and I largely can rely on a pre-selected aperture/speed/iso combination. On street photography I very often use shutter auto and use exposure compensation to adjust for highlights or shadows. Why? Because average lighting changes frequently - one shot is in the shadow of a building, the next on a bright piazza, the next under dim arcades and so on, and I do not want to spend the extra time to find the baseline for every single shot. On portraits I had the situation where I used exposure compensation with manual mode to ensure that skin tones are biased in the direction I wanted them to be. And so on.... Sometimes, it is good to have the option of exposure compensation, sometimes it seems superfluous. Edited July 28 by jgeenen Link to post Share on other sites More sharing options...

If aperture means "die Blende" then there is something wrong. But you certainly are aware of that . . . Link to post Share on other sites More sharing options...

If you are used to using full manual mode, then I think you should just continue doing so, without exposure compensation. That way, the exposure will be exactly as you set it, with no surprises. I do the same thing. 5 Link to post Share on other sites More sharing options...
Chris W Posted July 28 Share #11 Posted July 28 No idea what 'die Blende' means, no. To me aperture is f1.4 to f22...That's all I know. Link to post Share on other sites More sharing options...

But that is connected to a manual lens and the compensation cannot change that on an M camera 🙃 1 Link to post Share on other sites More sharing options...
charlesphoto99 Posted July 28 Share #13 Posted July 28 Exposure compensation is the gremlin you use once, for some reason, and then forget to reset it and screw up the next batch of shots. Best to just stick with manual and adjust shutter speed or aperture as needed. It actually takes the exact same amount of time to do so. Never really understood exposure comp myself (or auto for that matter). 4 Link to post Share on other sites More sharing options...
jaapv Posted July 28 Share #14 Posted July 28 Exposure compensation is very useful - if you have an EVF camera with Histogram in the viewfinder or can use the Visoflex as such. Then it allows you to set exposure very precisely before you release the shutter. On an M camera it is another story, for, as Charles mentions, one is likely to use it properly in the Visoflex once and then use the OVF and forget all about it. Some users set EV compensation to a permanent minus value from fear of blown highlights which is a mistake as well. Exposure varies per situation, it can be between -1 ½ and + 1 or even more depending on light and subject. Setting the camera to underexpose permanently will cost dynamic range on most shots. Going manual and using the arrows in the viewfinder is the way to go on an M camera (read the manual on the proper use) 3 Link to post Share on other sites More sharing options...

So it will attempt to change the ISO if it is set to Auto. Which will not change the exposure but the final brightness by software. Link to post Share on other sites More sharing options...

Chris W Posted July 29 Share #17 Posted July 29 17 hours ago, jaapv said: Which it cannot. I was getting it confused with the SL2-S, which I also use. I never use shutter priority and more and more never Auto ISO. I most often go between full manual mode or aperture priority If the camera has under exposed the subject a little because of a bright background, I've found I can lift the shadows and lower the highlights with good results in post. Exposure compensation is so easy to access on the SL2-S, I've been using it a lot more. On my M10 I tend to meter (manually) the top of my subject (inc sky) and the bottom (inc floor, path, road etc) and choose settings that more or less work for both, while understanding that my priority is correctly exposing the subject if I can.

jgeenen Posted July 29 Share #20 Posted July 29 vor 20 Stunden schrieb jaapv: Blende is German for Aperture. German camera, remember. I love those differences in meaning - „aperture“ is literally describing the size of the opening while the German word „Blende“ identifies the blades limiting that opening. Similar to English word „finder“ versus German word „Sucher“ - the literal translation of „Sucher“ is more like „searcher“ or „seeker“. It seems as if German language is describing the process to get to a result while the English language is describing the result. 4 Link to post Share on other sites More sharing options...
