>>4047858There are a few ways OP, all of which will involve some degree of moving away from auto, or post processing
>fix it in postYou could, provided you're shooting raw, just alter the exposure in whatever editing software you're using. Add long as you haven't clipped your highlights you should be fine. However, nobody really wants to spend all their time editing, doing it in camera is way more fun
>use exposure compensationYou could probably get something like the image you posted using exposure compensation. Basically you set it to make the image a few stops darker than the average exposure that the camera is gunning for. Really this depends on the scene, as your camera will still try to get a generally well exposed scene so might still fuck things up for you.
>use spot meteringYour camera can switch between different metering modes (probably. Read your manual). Spot metering will set the exposure according to the middle of the frame. If the light isn't in the middle then you have two choices. You might be able to link the meter weighting to the selected AF point (again, read the manual), or you can use the AE lock button. Put the lightest part of the picture in the middle of the frame, press the AE lock button and recompose.
A combination of those three will probably work for 90% of the situations you encounter, but the most flexibility comes from learning to manually expose. It's a really valuable skill to have for those times that the other techniques don't work, and you'll learn a lot about how your camera works and how to use light and shadow in the process of learning it. I'd really recommend it anon.
