I will be investing soon in a film body so I can really exploit the bokeh of my 70-200 2.8. I am wondering now whether it will be cost effective to do so almost purely for experimental purposes.
As a previous poster has already mentioned, "bokeh" remains the same whether you shoot digital or film. I suppose there may be a difference if you run the image under an electron microscope, but for all practical purposes, this is not a reason to use a film camera with your lens.
Also if I wanted to do a bit of darkroom experimentation is this a no go expensive area for a novice or would it be cheaper but more risky than processing with a mail order company.
Having had my own darkroom in the past, I can tell you this:
- Along with the associated cost of equipment (an enlarger being the most expensive), to become good enough to "experiment" in the darkroom requires lots of practice/study. Practice = burning lots of paper + chemicals + time. IOW, practice = money. If you're passionate and driven, you'll find a way. If you just want to play around without spending a lot of money, there are other options.
- You can not "experiment" using a commercial lab without paying huge money to have your images hand printed. If you choose mail order or a lab, they will process your film using machines and computers. What this means is your color will be "fixed". Your contrast will be "fixed". And your exposure will be "fixed". IOW, if you intentionally underexposed a sunset shot in order to capture the strong colors and dramatic lighting, your exposure will be averaged and your nice black shadows will become mud.
If you want the lab to print the image as you exposed it, shoot transparency (slides). However, even with transparency...without digitally scanning it into the computer or using an enlarger in the darkroom...your image is now "fixed". You can't adjust color/contrast, etc. To alter the image further requires a photo editing program or a darkroom.
Cheap options for experimenting in the darkroom:
Save on the cost of film/enlarger. Create a digital negative from your positive image. Then print on transparency and use as a contact print using one of many processes. The digital negative creation is described here:

Some of the processing options available for contact printing, including one of the simplest, cyanotype (aka, blueprints). For this process, you only need a sheet of paper coated with the chemicals and a UV light source such as the sun:
