Canon AE-1

[lennon33x]

Hi all
I'm new to photography and I've picked up 35 film before I go splurge on a dslr.

In developing recent rolls, I've noticed a couple of things:

1.) there is a bluish hue on some of the more brightly lit pictures. No filter was used on the lenses. Can a filter (Hoya 1B) reduce that?

2.) On some of my low light pictures they came back really grainy...I think my camera is reading the exposure for something much brighter in the frame (ie a streetlight) and is telling me to increase ss to accommodate for a brighter picture. Therefore the picture is underexposed. Thoughts?

Thanks
