Almost all of the photos that people are filtering are uploaded straight off a phone. Generally the cameras on these devices suck. You get tons of pixel noise, weak colors, and relatively low resolution. You also don't get much in the way of creative control, such as the ability to play with depth of field and exposure.

Filters cover up these flaws. You no longer see all the noise and general crappiness after taking a photo blurring it, overlaying textures, and then blowing out the color. Plus they give you a bit of creative control. I think that's the reason that these apps are so popular.

Thats a pretty good explanation. I always wondered why do people love filters so much.

I think another reason is because its "cool" now.
