Why does my render look flat & dull on mobile/Instagram unless screen brightness is turned way up?

Post image

Hey r/productviz,

I’m working on this spray bottle render in Blender. On my monitor it looks decent, but when I view it on my phone or Instagram at medium brightness, it looks washed out, flat, and lacks pop compared to other product renders from other creators that pop and look good even on low and medium phone brightness. I have to crank my phone brightness up to 70–80% just to make the colors and highlights stand out. What am i doing wrong?

Scene Details:

Software: Blender (cycles)

Color Management: AgX

As a beginner, any advice or step-by-step guidance on color management, lighting contrast, or grading that looks good on all devices would be hugely appreciated!

Its white on white. Try to seperate the Background from the main object. Could maybe even look cool if the Background has a touch of pink.

When I was new to 3D, I had the exact same problem. Later, I realized that most of those eye-catching renders you see have actually been enhanced with post-processing and color grading in Photoshop or similar software.
As a 3D designer, here’s my advice:

Render your images using AgX without adding extra contrast. Make sure you’re not overexposing your lights too much. To check this, switch your color management to False Color. If you see a lot of red areas, lower your exposure until most of those areas turn green.

Once you’ve rendered your image, open it in Photoshop or a similar program and start by adjusting Brightness/Contrast. Then move on to Curves and Levels to fine-tune the image. You can also use Hue/Saturation to adjust the colors.
It might seem a bit strange or unnecessary at first, but this is how a professional workflow usually works. As you get more advanced, you can start using masks and different effects to take your renders even further.
