try sing old school lenses=) they have different coatings or simpler designs and mostly optimized for BW shooting. you get the 'old school contrast'. but each lens has its own "character" so might have to try afew. so far i like minolta MC, canon FD and some old yashica glass. no $ to try ziess r leica so not sure about those.
Ben, old lenses may not be the best investment for me as I'm on a budget for experimenting, but thanks.
Nightmare, thanks for the short post-photo explanation of the photos.
I'm interested in the "high contrast and saturation" effect.
Do you know where I can find such tutorials, will do a search as well.
i don't think this is particularly focused on emulating a lomo look, one thing is missing for sure, the vignetting.
cross process is not hard to find, for high contrast and saturation, just look for tutorials on "curves", the xpro tutorials should touch on these as well, albeit with individual curve channels rather than the general curve channel.
btw you should take note of the fact that high contrast and high sat can be very nice, but in some cases, like the ones where you have posted, having a riot of colours can lead to a generally messy feel about the picture. so applying it at the right place at the right time is just as essential as knowing how to apply it.
for high contrast, try this setting in ps.
go to channel mixer, increase each channel's main colour to 150% and the remaining two decrease to -25%. so it becomes: red channel (R = 150% G = -25% B = -25%), Green channel (R = -25% G = 150 % B = -25%), Blue Channel (R = -25% G = -25% B = 150%) that should gives higher contrast. Good luck
