I am beginning to get interested in lomography, and I was wondering if I could do it with a regular camera. (I have a digital slr, will that work?) All the photos of lomography I have seen seems as if they have extremely high contrast, and deepened depths of field. Is there a way to not buy a lomography camera and get the same results? Im getting back into photography after a long break and am really rusty! Thanks to anyone who answers!

Some of the high contrast and crazy colors is because the film was cross-processed. That means color print film developed in the "wrong" chemicals like for slide processing.
Lomography (derived from the LOMO company name) is a marketing thing to re-spin photography in a counterculture way (like it wasn’t done enough in the 1980’s, you can see some examples from photo magazines of that period.)(Chemical based photography is 100 years old, so people have been trying it chemically "wrong" occasionally).
Kind of like saying "Nikon-ography or Canon-ography".

Deep depth of field comes from lomographic cameras having f/8 or f/11 as their only apertures (with deep DOF) and the lenses may tend towards wide angle, (more deep DOF).

Lomographic cameras are also based on cheap cameras from the 1960’s with plastic lenses. So the clarity, and focus, and contrast of the best special glass (and best special lens coatings) are not in the picture.

You can also use different colored filters in front of the lens, and put vaseline or plastic on a clear filter to get the hazy or dreamlike effect (also use f/8 or f/11 with a wide or fish-eye lens). And also shoot from odd angles.

Once the image is digital from DSLR, then you can use Photoshop or GIMP and manipulate the colors, the contrast, clarity, and the focus, and cut/paste sprocket holes or frame numbers. Then call it "GIMP-ography"
