No filter

With Twitter having released a new version of its mobile app on Monday that allows users to add filters, it is now competing directly with Instagram. But while Instagram offers 18 free filters, Twitter launched with just eight.

Still, it is interesting to compare what each of those basic filters look like. So CNET took a single photograph and filtered it using every available basic option in both Twitter and Instagram.

This is the unfiltered photo, taken in Berkeley, Calif., at sunset.
