And since I know you use flash in the field most of the time, this means you should pretty much *always* have it at 100.
Case in point your other butterfly image. Incredible composition, but the high ISO destroys contrast, color definition, etc. It's still awesome but you're needlessly sacrificing image quality.
Got 2 Litra cubes now huh, told you they're awesome :) Posted 4 years ago
How can I lock the ISO at 100 AND use f/16 consistently? Just by increasing my lighting to compensate? Or letting the camera choose the shutter speed alone? I don't know how to set ISO and f-stop at the same time (manually), but I'm sure it's in the handbook that came with the camera.
What other butterfly image? This one?

Note how ISO 6400 makes it a bit muddy, lack of definition, micro contrast and even some loss of color. That we will solve!
I'm not a Canon user, but some ways to lock both ISO and aperture:
In my case (Nikon), I simply set ISO to 100 and use aperture priority mode. Next, I set the aperture and the camera figures out how long to expose given this ISO and aperture. I don't need to do anything special for this other than setting the ISO. I suspect you may have some auto ISO setting enabled. Disable that, you should almost never use this.
I'm thinking this should be possible with Canon too. If not, there Manual mode (M) where you can lock all 3 exposure values. Downside is that you need to trial and error the shutter speed.
Hope you manage to find the settings, this may be an exciting improvement. To be very clear, your photography is excellent, it's just that your technical image quality can be even better by keeping ISO at 100. Posted 4 years ago, modified 4 years ago
I do have auto ISO settings enabled. I need to find my manual and set aside time to read it. I really don't want to use the completely manual mode because it become more of a headache when dealing with shutter speed too. But, setting the ISO makes sense and would undoubtedly be a good idea.

Compare the butterfly to this other image of yours:

Note the fine details in the fungus. Sharp, micro contrast, very clear "definition". Comparatively, you can't "count the hairs" on the butterfly, it's a bit muddy. Could in part be because it's a dark subject, of course. Posted 4 years ago
I glanced quickly at my camera manual and it doesn't look like I can choose both manual ISO and f-stop without using the manual mode. But, I'm going to read a bit more about it because I might be missing something as I only had 5 minutes to read it during our morning school break. Posted 4 years ago
