A few days ago, I got myself a Canon EOS 700D DSLR camera along with a Canon EFS 18-55mm lens for about $160. Until now, I’ve only ever used point-and-shoots, like my smartphone or my “Kodak” Pixpro AZ401.

So, it’s basically the first time I get to properly play around with the exposure triangle and all that good, manual stuff. I already love this camera, because despite the low cost, you can get great shots in auto mode out of the box, but it’s also very versatile in professional photography. All that, and I still haven’t even gotten into editing raw photos; this is just the JPG!

This particular photo of a garden shed was shot with:

ISO: 6400
Exposure: 1/395s
Aperture: f/14
Focal length: 46mm
Resolution: 5184x3456

From what I’ve heard, those settings aren’t ideal, especially the high ISO for that much light. Does anybody have some general tips for me or resources to check out?

By the way, I also just installed Magic Lantern. That’s some great stuff. Oh, and also - if anyone has a good way to connect it as a webcam on Linux, that’s also very welcome since EOS Utility doesn’t work and Gphoto2 is very low-res. The first thing I didn’t get properly running on Linux!

    It is all about trade-offs, but the tradeoffs have to be situational.

    Considering only shutter speed and a “static” subject, you have to consider whether or not your subject is actually static. For example, are there flexible things present (plants, etc) and is it windy? For something like a desert landscape with zero motion your shutter speed can be as low as you want it to be (note that you might need to block some light from reaching the sensor using a ND filter). For “still” people you probably don’t want to go too low because we’re constantly in motion. That said, ever rule was made to be broken. Want to photo stars? Don’t use a super long shutter speed - you’ll get star trails. What’s that, you want star trails? Bump shutter speed even more so they look intentionally vs somewhat smeared balls of light. Sports and wildlife are basically the only scenario where you need a fast shutter speed… until you want some motion blur. Granted, motion blue and sports will still probably be a fairly fast shutter speed.

    Aperture follows a similar arc - do you want shallow depth of field, do you want to see more of the foreground/background, maybe you forgot your ND filter and want a slow shutter so you have to stop down, maybe it’s really dark so you have to use a fast (wide aperture) lens wide open.

    The only thing you universally want to take one way is ISO and that way is low. Unless you want some grain. Or you’re shooting something with motion indoors and you can’t compromise any more on shutter speed or depth of field. Or your lens aperture is already wide open and you still need more light.

    When staring off you might want to try shutter or aperture priority, based on the situation, and let the camera handle the other two values. Heck, I still do this 95% of the time 15 years later.
