Tips and trick for white on white?

[Esben Oxholm]

Hi guys.

I'm struggling to do a studio shot of a product made from white rough abs on a white background.
Have any of you had luck with something similar, or tips for good hdr's to use? Render settings? Other rule of thumb when rendering white on white?

I can't show you my scene,  but either it gets to dark or to blown out and just look very CG.
The model is pretty simple, but has got rounds, fillets etc. needed for injection molding.

Thanks in advance
Best regards.

dig into the vaults of keyshot website tutorials (or search youtube).... I have a vague memory of watching one doing a white ceramic sink on white background.

Also, play about with the gamma and brightness sliders in the settings tab. It can be tricky if the background has to be 'absolute' white.

Not sure what else to say.

Esben,

Here are some tips & tricks that I use for white-on-white.

• Set your white material's diffuse color less than 100% white. I usually use 85-92% brightness for white plastics. Reason being: no plastic material will reflect 100% incident light.
• Try an HDRI with several light pins/ several distinct light areas. This will ensure that e.g. in an animation your whites will remain, well... consistently white.
• Use an HDRI without colors (duh!)
• Set your environment contrast relatively low. The value will depend on the HDRI used. For typical studio HDRIs I tend to stick to a contrast between 0.8 and 0.9 when I'm doing all-white renders.
• A lower contrast and higher brightness works better than a higher contrast and lower brightness. At least for white products...
• Maybe try a radial gradient backplate as a stage for your product.
• Doing minor tweaks in post can really boost the appearance of white products. Think about curve adjustments, levels control...

Hope it helps...

Thank you guys.
By adjusting gamma and brightness, not using a 100% white material, using lots of pins in the environment, reducing environment contrast and tweaking the levels in post, I came up with a result that was way better than the starting point and made the client happy.

I owe you one
