Best Way to archieve Clean and (very) sharp renderings

Hi, a question to the forum

I saw this pictures from the forum. I never get those perfect clean and adorable sharp renderings!
How I archieve such clean and sharp images? Noise less 1%? Large Renderings..? All in the post…?

Some Hints will be great

best, Tom

Its too sharp for my tastes, but it’ll be a combination of those things. Noise below 1% sounds unnecessary to me, but a larger rendering scaled down for the web will look sharper. Plus its probably been sharpened in post. Try this:, get an image of yours in photoshop, duplicate the layer and put it above the original. On this new layer run Filter>Other>High pass> radius of 2-4 - something like that. Then set this new layer to soft light or hard light and adjust the opacity.

As far as I can tell, there is :

  • Chromatic aberration (not really shaprening)
  • Some sort of shapening filter (or bad AA, but I don’t think so because the grain is really limited), you see that mostly on highlights
  • Very low noise indeed - long render time or a big farm… depends ofc on the resolution, if it’s pro work, it’s minimumm 4k renders

That being said, a noisy 4k render (80/100 passes) resampled in 1200 pixels wide will be more or less noiseless. A lot of images looks nice in small resolution but hurt the eyes in bigger size.

To try custom sharpening, you can use in photoshop

  • duplicate layer
  • high pass (play with the numbers/ low values = sharpening/ high values are more like “clarity” tool in lightroom)
  • put this layer on soft light blending and play with opacity

This tends to accentuate existing grain so working on a noisless image is better (you could always add grain afterwards for “artistic” reasons)

Best would be to have a word from the artist who made the image :wink:

Haha, we answered with the same workflow in photoshop at the same time :wink:

Try values as high as 40 / 50 or even 100 on 4k renders, it sometimes yields intresting results.

thx for the hints!

40-50/100 for High pass…? wow I never tried so high settings…I’ll try

yes…because the textures (especially the leather) are sharp, maybe these is another reason…but I mean pics with more distance. Look at this: the flowers and the contour of the eames-chair are very crisp
