you know what really grinds my gears?

When people call an n dimensional array that only holds data and in no way represents a linear transformation, a matrix.

Does it really make sense to multiply images?

It makes sense to multiply an image by a transformation matrix (translating, rotating, scaling)

It makes sense to use multiplication for convolution effects (blurring, edge detection)

It makes sense to multiply two images' rgb values together (multiply blending in Photoshop)

ofc none of these examples are straight-up matrix multiplying two images together
