15 years running Cerebro Digital (8M followers, no ads) taught me the loop: spot the story early, add your take, publish everywhere, daily. The tools never connected and people burned out. So I'm building ViralHunt: radar, board, 11 networks, and agents that draft while a person approves. viralhunt.io

One thing I keep seeing in marketplace seller groups: photos shot on a white poster board still look gray once uploaded. That's because camera metering renders a white sweep as light gray - the pixels sit around 240-250 instead of 255. Marketplaces normalize to pure white, so the difference shows up as a visible gray box in category grids. What actually works: don't chase the exposure slider (product highlights clip along with the background). Cut the product out and place it on a fresh pure-white canvas - uniform 255 white behind an untouched product, no matter how the original was lit. I build a little browser tool that does exactly this cut-and-fill in one click: https://cleanwhitebg.com - upload, get a white background back, re-upload to the marketplace. Full disclosure: it's my product, so weigh this post accordingly. Curious what sellers here do for white-background requirements - re-shoot, edit manually, or automate?
