What things should one take into account when looking at cropping a photo?

I found this question 9 years after the fact, but I just liked how many things the original photo said to me. It's a really good example of "What do you want it to say?" so I thought I'd have a go at ...

What's the best way to choose the aspect ratio: in-camera JPEG or RAW and cropping?

As the sensor is 3:2 that's the natural size to choose when shooting. Cropping can be done in post, where you have any option you want. If you crop when you shoot you waste pixels. In my experience ...

Why did the store crop my images for 4x6 prints?

I'm assuming you probably used a compact type camera with an image shape of 4:3 (long side of image is 4/3 longer than short side, which describes a "shape"). But a 6x4 print is the shape 3:2... ...

More megapixels to compensate for small zoom (Or: How good is Sony's Smart Zoom?)
