A few shots from my latest foray into the park came out looking like this, what I would call filtered. Not sure what else to call it. It was a sunny day, but I was in fairly thick woods. I am using 400 ISO Kodak black and white loaded into my ebay-obtained Pentax K1000. I got this particular shot at 250 with the f-stop set at 8. What can I do to not have this happen? Thanks in advance.
