What were the first filters available on Instagram?

When Instagram launched in October 2010, it offered 11 filters to users. The original 11 filters were:

1. X-Pro II
2. Earlybird
3. Rise
4. Amaro
5. Hudson
6. Mayfair
7. Lo-fi
8. Sutro
9. Toaster
10. Brannan
11. Inkwell

These filters helped Instagram to stand out from other photo-sharing apps and contributed to its rapid growth in popularity. Over time, Instagram has added and removed various filters, but the initial 11 played a significant role in shaping the app's visual identity and user experience.
