Well, a couple of things:
1. It's a forum full of technical people for a technical program. I'm gonna take a wild, crazy guess and say that they probably get a LOT of questions thrown their way. And for many, it's hard to see enough good reason for that when Google... and AI... exist, since those can be used to find answers. What I mean is, they probably get a lot of questions that could be answered with a quick search and some scrolling, and that gets on their nerves fast. So, any question perceived as such quickly goes south. Particularly if said person is used to Googling the heck outta things to get answers themselves... then they're probably thinking "geez, I use Google and find answers all the time, this guy asking me needs to just do that".
Anyway, just to see what would happen, I went and pitched the question at ChatGPT to see what it might do (I asked how I would get a final render that looks like it was done on a "poor quality camera" since that's the term I always associate with the type of image you're after), it gave me this, just expand the quote to see it:
To make your final render in Blender look like it was taken on a poor-quality camera, you can use a combination of techniques to mimic the visual artifacts typically associated with low-quality cameras. These techniques include reducing resolution, adding noise, adjusting color balance, and adding lens distortion.
1. Reduce the resolution:
In the Output Properties tab, set a lower resolution for your render. This will help to mimic the low resolution of a poor-quality camera.
2. Add noise/grain:
- In the Compositor, enable the "Use Nodes" option.
- Add a "Noise" or "Grain" node by pressing Shift+A, going to "Texture" and selecting "White Noise" or "Musgrave" (for grain).
- Add a "MixRGB" node by pressing Shift+A, going to "Color" and selecting "MixRGB."
- Connect the "Color" output of the noise/grain node to the "Color2" input of the MixRGB node, and the "Image" output of the Render Layers node to the "Color1" input of the MixRGB node.
- Adjust the "Factor" slider in the MixRGB node to control the intensity of the noise/grain effect.
- Connect the "Color" output of the MixRGB node to the "Image" input of the Composite node.
3. Adjust color balance:
- Add a "Color Balance" node by pressing Shift+A, going to "Color" and selecting "Color Balance."
- Place the Color Balance node between the MixRGB node and the Composite node.
- Adjust the Lift, Gamma, and Gain wheels to change the color balance of the render. This can help mimic the color imbalances often found in poor-quality cameras.
4. Add lens distortion:
- Add a "Lens Distortion" node by pressing Shift+A, going to "Distort" and selecting "Lens Distortion."
- Place the Lens Distortion node between the Color Balance node and the Composite node.
- Adjust the "Distort" and "Dispersion" sliders to add lens distortion to the render.
5. Add chromatic aberration:
- Add a "Separate RGBA" node by pressing Shift+A, going to "Converter" and selecting "Separate RGBA."
- Place the Separate RGBA node after the Lens Distortion node.
- Add a "Combine RGBA" node by pressing Shift+A, going to "Converter" and selecting "Combine RGBA."
- Add a "Translate" node by pressing Shift+A, going to "Distort" and selecting "Translate."
- Duplicate the Translate node twice, so you have three of them.
- Connect the R, G, and B outputs of the Separate RGBA node to the Image input of the three Translate nodes.
- Connect the Image outputs of the Translate nodes to the R, G, and B inputs of the Combine RGBA node.
- Slightly offset the X and/or Y values of the Translate nodes to create chromatic aberration.
- Connect the "Image" output of the Combine RGBA node to the "Image" input of the Composite node.
After setting up these nodes and adjusting their values to your liking, render your scene, and the final result should look like it was taken on a poor-quality camera.
That's what it gave me after asking a quick question. Maybe that'll help you? (It might help ME later, I've actually been meaning to learn Blender and this sounds like something fun to do with it).
But back to the "dealing with the forum guy" bit, also, with stuff like this, one way or another you cant expect someone else to 100% fix your problem for you. You're the one that has the files you're working with, and you're the one that's gotta do some learning, or you're not gonna advance. Sometimes that means experimenting, trial and error.
2. Some people are also just irritable, or their patience for stuff like this wears off quickly. Like, I'm generally fine with people asking me "how does X work" IRL, but after like 2 or 3 questions, I'm gonna start to get annoyed at them. Why? Because I have little patience, that's why.
3. It's the internet. Sometimes there is no reason. Nothing you can do about that.
One way or another you've got zero control over what the other guy does, and how he does or does not respond. And zero control over who helps and who doesnt, or if anyone helps at all.
And with technical stuff like this, sometimes you just gotta figure some of it out on your own... been there, had to do that. Yes, it's annoying. Gotta do it anyway, often.
