I'm just wondering if I've been submitting my work under the correct category?

I decided to take a little trip over to the Photomanipulation corner of dA, and noticed that my work doesn't really fall into that category very well, actually, it really doesn't belong in there I don't think!

I always thought my work would best suit the Transportation section under Art Photography, but upon submitting it notes:

"Pictures taken with a film or a digital camera featuring a very minimal level of digital manipulation. Photographs that feature a significant amount of digital manipulation should be filed under Digital Art: Photomanipulation."

I always take my photos into a desired program and work with them, using colour and contrast tools, so assumed I'm photomanipulating?

I've looked around, and there isn't anywhere else I can put my work. Would it be safe/better/more correct if I started submitting to Transportation under Art Photography? I'd like your opinions, because after all, you guys are viewing my work!

Thanks mucho!

P.S. Double thanks to those that have me on watch and like my work, it's inspiration to keep them coming!
