Depth of field is the range within which focusing is resolved in a photo.
Aperture has a huge affect on to the depth of field.
Changing the f-stops (f/#) of a lens will change aperture and as such the DOF.
f-stops are a just certain number which is telling you the size of the aperture. That’s how f-stop is related to aperture (and DOF).
If you increase f-stops, it will increase DOF, the area in focus (and decrease the aperture). On the other hand, decreasing the f-stop it will decrease DOF (and increase the aperture).
The red cone in the figure is an angular representation of the resolution of the system. Versus the dotted lines, which indicate the aperture coverage. Where the lines of the two cones intersect defines the total range of the depth of field.
This image explains why the longer the depth of field, the greater the range of clarity.
If you’re serious about protecting your IP, client relationships, and professional credibility, you need to stop treating generative AI tools like consumer-grade apps. This isn’t about fear, it’s about operational discipline. Below are immediate steps you can take to reduce your exposure and stay in control of your creative pipeline.
Use ChatGPT via the API, not the public app, for any sensitive data.
Isolate ComfyUI to a sandboxed VM, Docker container, or offline machine.
Audit every custom node, don’t blindly trust GitHub links or ComfyUI workflows
Educate your team, a single mistake can leak an unreleased game asset, a feature film script, or trade secrets.
The power output of a light source is measured using the unit of watts W. This is a direct measure to calculate how much power the light is going to drain from your socket and it is not relatable to the light brightness itself.
The amount of energy emitted from it per second. That energy comes out in a form of photons which we can crudely represent with rays of light coming out of the source. The higher the power the more rays emitted from the source in a unit of time.
Not all energy emitted is visible to the human eye, so we often rely on photometric measurements, which takes in account the sensitivity of human eye to different wavelenghts
