20 smartphones have been randomized and assigned a letter. All of them take the same photo. You'll be shown a comparison side by side, and you pick the better photo until a statistically significant winner emerges.
He's pit 20 models this year divided into the same three categories as last year (standard or daylight shot, low-light and portrait). I got the OnePlus Open, Pixel Fold and 7a for the standard test, Pixel 8 Pro, Pixel Fold, Pixel 7a for the low-light test and Oppo Find X6 Pro, iPhone 15 and Galaxy S23 for portrait shots. Wish he'd also include an ultrawide and zoom category but I can understand why he's not doing zoom because different phones would win at different zoom levels as some phones have a 2x lens while others have a 3, 3.5x, 4x, 5x or 10x lens.
