Hello friends.
I'm doing a job for ceramic products, in this scene
I see that I lose detail or sharpness in some parts.
I wanted to know if there is a way to get the best possible detail of objects
and textures?

this render that I show has 100 pass without denoise

I take this opportunity to remember to include the vertical and horizontal shift in the parameters of the camera.
this would be of great help for shots with tilting angles such as Vray already has.
Thank you

Is it displacement or bump? I am thinking displacement.

You could adjust displacement quality in the Performance settings tab, either lowering the Screen size, or swapping to World size - however, both will increase memory requirements, as they generate finer displacement.

Of course, detail would fade with distance and begin to blur together, even with a camera. So other options that don't involve adjusting the scene itself and that might get you a look that you prefer, you could use Sharpening / Blurring. You could also render to a larger resolution and downsize to see if you prefer how that looks. Or you could shift GIvsAA balance to give more priority to anti-aliasing.

use displacement, I changed the parameters you recommended and improved the detail
Thank you

Just use the Film Offset X and Y (see pic), that should work.

thanks for answering. if it works that way but !!! Not for all cases.
In architecture sometimes shots are made with very sharp angles.
For that case, Vray has those parameters in his camera.
It would be spectacular if Corono included it too

Could I ask you to be more specific and show some examples, please? Forgive my ignorance, but I'm a mere programmer, you know :-)

As a note, the Max Corona Camera does include Tilt and Shift, so hopefully there is a way for it to be ported across :)

This is the example:
I already talked about this topic in another topic, I do not want to be reptilian.
I just wanted to take advantage of the occasion.
Thank you

Is that in Max, and in cinema? ;)

Apparently Cinema Cameras already have this control, so it isn't in the Corona Camera Tag (as that would be redundant) - going to test it just now, hopefully :)

it does not work in the same way, that's why Vray brings it.
But!! it does not matter, let's leave it like that,
It was just a suggestion
Anyway, thank you ;)

Yes looks like it is just the Shift that is in the default C4D cam, not the tilt (nor auto tilt). We'll keep it under consideration as an addition and see if it might be possible.

guys as a photographer i tell you that shift is very different from tilt. We talked about this in a previous post https://forum.corona-renderer.com/index.php?topic=16562.msg104381#msg104381

i attach here some image that explain the difference. Last thing, if shift is the same of tilting, why lens productors make tilt shift lens?! for example: Nikon PC-E NIKKOR 24mm f/3.5D ED, Nikon 19mm F4E ED PC Tilt-Shift, Samyang 24mm F/3.5 ED AS UMC Tilt-Shift, and many many others. With tilting you can also make interesting DOF effects, check the works of Olivo Barbieri called "Site specific". Tilting is not an must have feautures, but can expand a lot the creative possibility of using corona render...

You could still create a geometry lens in front of the camera for direct control.

Credit goes to Shawn, inspired his chromatic aberration video.
