It's fascinating to see what people have made of this and I really like what I'm seeing!
Here's mine; I also did multiple versions, and ended up selecting four I wanted to share. They have a lot in common in that they stay close to the literal image as it's on the negative, and I also ended up using virtually the same crop on all versions.
I started by scanning the negative, also because the scans were to be made available to everyone to play with. But for my own version, I also started playing with the image a bit in GIMP to see how I'd like to approach it. I decided that I wanted to keep that one car smack in the middle and emphasize it. From there, I tried to balance out the composition while keeping as much as possible from the image. I then selectively adjusted contrast across the image by making a stack of half a dozen or so layers with curve adjustments for specific elements - the car, the grass in the foreground, the sky, etc. These layers were assembled into a single image using selective masking. Finally I added a border and split toning, and some post-resize sharpening. This resulted in the version I based the 'real' prints on.
For the actual prints, I decided fairly quickly that I'd want to use this as 'target practice' for lith printing; the derelict cars invite some form of grittiness and lith seemed an appropriate way to get there (besides, it's been ages since I got to play with lith, so this was a good excuse). However, the negative was kind of dense for the long exposure times I'd need with lith. I did some attempts and just didn't like the result or the long exposure times. So I went the full monty and made a duplicate negative via an interpositive, using x-ray film.
I used this negative for the actual prints. The negative is ca. 10x7cm (image area).
I started with some straight prints on Adox MCC110. I didn't really like these to be honest; not enough zap, or zing, or what-have-you, despite doing some burning & dodging to create a similar emphasis as in the digital version. I ended up working on one of these prints afterwards; I did some bleaching to brighten the sky and used a combination of sepia and selenium toning. It's OK, but not what I was going for.
Enter the lith experiment. I mixed up some simple lith chemistry from raw ingredients and worked with two papers. Below is a print I made on some old Orwo BS1 single weight paper which turns out to lith quite well, albeit not very colorful. Same overall pattern of burning & dodging as in the previous exposure. The print was a little on the flat side, so I ended up toning it in gold almost to completion, followed by light sepia toning to warm it back up a little.
I figured I wanted to make things more colorful and bold. I exaggerated the burning & dodging on this one, and used Fomatone MG to get more color from the start. I also used a dual developer approach I gleaned from Moersch' 'polychrome' technique. I started with a regular lith developer and then when the shadows were where I wanted them, I went over to a very dilute and heavily restrained metol-only developer to add color. This was further enhanced afterwards by toning in sepia and gold.
Ultimately, I personally prefer either the digital/hybrid version for its 'cleanness', but the first lith print (the more monochrome one on the Orwo paper) is the closest to what I had in mind at the start. It has the gritty feel to it I was after.
