Nah look at the sand on the top of the image. There are no buildings there, so why is it vividly colored in the top image and has zero colors in the bottom image? Someone has turned up the saturation on the top image to 11 and 0 on the bottom image.

Like what is happening in Gaza is terrible, but stuff like this just gives the other side something to shoot at. And I feel the image would hit harder if it were a fair comparison, so the same settings for both. The beach still being beach colored and the streets being gray with rubble would hit hard.

The reason he mentioned weight-loss is because it’s a trope that people showing before and after pictures of weight-loss often use techniques like this to show a more pronounced (or even any) effect. In the before they have bad posture, use an unflattering angle and reduce the colors to make them look worse. In the after picture they have perfect posture (often even holding in a breath and clenching muscles), use a good angle and crank up the saturation a bit.
