So I have developed my first roll of C-41 using my water bath and aquarium heater/water pump setup. For the most part I'm pretty satisfied with the results,but there are a couple questions about the way the film turned out. Specifically, some of the pictures have really bad grain, and the picture of the table saw seems to have a lot of something. Below is the link to the pictures and I would really appreciate some feedback and comments.

The pictures were taken with a "new"(to me) Maxxum 300xi, set to automatic with kodak max 400, in my mother-in-law's house and basement of random things.
