Wow. Thanks for making this! As an analog photographer, this is what I've been looking for. I've bookmarked it for future reference.

Here are some points I noticed (no dealbreakers):

- On the landing page, it would be nice to be able to simply scroll down to see some content. Now the call-to-action button is there but why not show the main content below the "hero" image?

- On the page with the film rolls: would be nice to have the specs of the film rolls on this page if you hover over a particular roll. E.g. replace the image of the roll with the technical specs. If not the technical specs, then at least the short description that you have on their individual pages.

- The pages for a specific film roll are tagged (e.g. "street", "General purpose", etc.) but they are not clickable. It would be nice to click on the tags and see what other film rolls are available with that tag.

- For the example images: add arrow-key navigation (I noticed Esc key works, which is nice)

- Not all pictures scale to full screen (e.g. the first image here https://filmtypes.com/films/ilford-delta-100). Is the resolution too low of the original image?

- I realize you want feedback, but the chatbox in the lower left (edit: lower right) annoys me a bit. It is easy to dismiss with a large X to close, so it boils down to personal preference. Have you gotten good feedback from it? If not, maybe consider making your feedback email address more prominent.

edit to add:

- Consider making an "info" icon and place it next to "Specs" on each individual film roll page. When clicked, a small pop-up can be shown that explains what you mean by contrast, color tone etc.
