Some of the popular manipulations that disqualify photos from TTG:

• Adding AI-generated content (AI-GC)
• Fokeh/non-optical bokeh blur (“Portrait” mode)
• Magic Erasing
• Post-exposure “perspective correction”
• Use of Pano mode
• “Live” and “Motion” photos that are not saved as a still frame
• Added lighting effects
• A unique post-processing “look”
• Darkening the edges/corners of the image beyond lens effects
• Combining different people’s smiles from different exposures
• Inserting the photographer into a photo that they took
