Product of a wet miserable Saturday evening!
Taken using my 'enigma' lens that has no focussing, hence the use of a helicoid.
Auto Mamiya - Sekor 55mm f1.8
So there has been a bit of post-processing - a bit more colour, a bit more contrast, a bit of brightening, all of which could have been done in-camera beforehand. Warm light sunny light this morning.
However this wasn't a great posed shot but something quickly arranged and 'snapped' on the 'what if' basis.

Gathered up the little bottles on my desktop to store in their box, and then got called-away.
Returned, looked, wondered, grabbed the camera and took this.
A bit of post-processing - nothing drastic.
The lens is an enigma. Bought, found to be faulty and unusable because there was no focus possible. A partial disassembly, some glueing, use of a spacer and a helicoid adapter, has given a range of focussing within 15 feet. Not ideal but a possibility for taking photographs on the desk-top, like this one.
Was it worth it?
I think I will buy a working replacement but in the meantime ....

Three small bottles, then the much older green, followed by seven more small ones!
I didn't know what the lens would produce with this flat natural light - no bokeh balls but this rather dreamy look resulted.
The bottles are on my desktop and lined up with a ruler.
A handheld shot - the second of just two.
