Which file format should I use for images with transparent backgrounds?

Use PNG-24 or WebP with alpha for the web; avoid JPEG since it has no transparency. Check marketplace support, as some platforms still require PNG.

How do I remove color fringing around hair after background removal?

Slightly contract and feather the mask, then use Decontaminate Colors or Defringe. On a new layer set to Color, brush sampled background hues to neutralize spill.

What canvas size and resolution should I export for ecommerce and social?

For Amazon, use at least 2000×2000 px (longest side ≥1600 px) at 72 ppi. Instagram feed 1080×1080, Story/Reel 1080×1920; Facebook link ads 1200×628. For print, export at 300 ppi.

How can I make a realistic shadow when placing a subject on a new background?

Create a soft contact shadow under the subject on a new layer set to Multiply, blur it, and reduce opacity. For cast shadows, duplicate, fill, skew, and blur to match light direction and color.

When is a plain white background better than a colored or scene background?

Use pure white for marketplace compliance and maximum contrast. Choose brand colors or subtle gradients for campaigns, and lifestyle scenes when context boosts conversion.

How do I keep edges sharp without looking cut-out or fake?

Feather selectively based on material, add slight grain to match background texture, and align depth of field. Avoid oversharpening after export.

Can I automate background edits for large catalogs without coding?

Yes. Most editors support actions, presets, and batch processing; some add command-line or scripting. Standardize inputs and include a sample-based QC step.
