Cost was probably about £35, but it is a while ago so you'll need to check the current going rate.
Hope that helps!

With film, filters can control the tonal values in black and white, but exposure for the shadow areas gives the best result.
With transparency film and digital exposure for the highlights is the way to go to avoid total loss of detail in the lightest areas.
However, with digital we can also make selctions and alter tonal values in selected areas of the image. This can also be done in the darkroom, but is much more difficult and demands very good technique.
Very often these days if I don't like the sky in a lanscape I don't include it in my composition.

In this digital age, when we all check our histograms to ensure we haven't blown the highlights, I think we often think that we have to keep them in the final image. This was never the case before, when we couldn't check the histogram of our prints, so I don't think we should be so hung up on it now. By all means start with the best 'negative', but if the best print has pure white or pure black elements to it, so be it.
In other words, I agree with you!

As an example, I use Paterson FX-39 to get a very sharp grain structure. Not the finest grain, but no trace of mushiness and a really crisp result.
For finer grain and a good well rounded negative you could try Paterson Aculux 2.
Both of these are liquid concentrates and more convenient than mixing powders.
It sounds like your equivalent to Channel Mixer is the way to go.

If it's colour film then a professional lab will be worth the extra cost.
How do you convert to black and white? If you are using Greyscale then that could account for the flat results. The best method is to use Channel Mixer in Photoshop, which will enable you to adjust the exact tonal balance.

The alternative to scanning, if your scanner is the weak link, is to tape a medium format negative to a light box, make sure the room is dark to avoid reflections and use a macro lens to make a direct digital image with your DSLR. On the face of it, this should give better results than you are getting now.

Maybe i'm completely wrong, but the one time I shot in jpg, I didnt like the quality of the results (this was just some things round the house), went back and shot in RAW and it worked out alot better.
In general, if the photographer pays proper attantion to getting the image right at the point of capture, as you would if you were shooting transaparency film, then the difference between RAW and JPEG capture will be very, very difficult to see, even at A3 print size.
We ran tests with a large audience at ADAPS and most people could not tell the difference. Of those who could, depending on subject matter sometimes RAW was seen to produce superior results, but also sometimes JPEG was. So the situation is not totally in favour of either type of capture.
