And I must give credit where it's due for the idea of putting a short tube on an FA77mm ltd lens or similar - it came from LennyBloke (as did the lens and tubes, too :wink.

A few years later, he started a 'sticky' thread in 'General Digital Photography chat that expanded on the articles and wandered into what other people did for sharpening. Here it is:

Does anyone fancy producing an update on sharpening that takes into account developments over the last decade ?
Over to you, folks ...

What did you do?
2. Choose the lens. From past experience I knew that the FA77 with a short tube could do this sort of thing. For the ultimate in sharpness I'd have used a macro lens.
3. Choose a fairly wide aperture (f3.2 as it happens, I thought it was f2.8!). Guaranteed very shallow DOF so almost everything in the picture would necessarily be soft.
4. Choose the light. Foliage surrounding a flower or bud would give a green cast to the light, which seems to help with giving a feeling of softness. (I first discovered the effect of reflected green light when the underside of a low flying skylark appeared strangely green in a photo. Never forgot that one!)
5. Hand held, manual focus (no AF with a tube so no option :wink, body (mine, not the camera) in strange positions (). Almost guaranteed to ensure nothing would be razor sharp. For ultimate sharpness the tripod would have been used.
6. Evolve towards the right picture. These weren't the first buds and flowers photographed in that session. It started with a red fuchsia but that didn't seem to work so went to pink and worked through several flowers and buds until light, background, surrounding foliage etc. looked right. Then I tried some more and didn't find any better.
7. Use what's there to advantage. The green haze over most of the lower part of the first photo is from a leaf that was very close to the lens and protruding part-way across it. Moving it out of the way did cross my mind (I prefer not to remove bits of plants unless absolutely essential) but the view through the viewfinder suggested otherwise. So really just a bit of luck that a leaf turned up in the unexpectedly right place - sometimes luck is on your side .
8. Don't show the shots that didn't work...
AI Denoise and Sharpening are not demons. It depends how hard you hit them.

When in Av: Back wheel changes aperture, front wheel changes exposure compensation.
AF: Back button AF, do not AF with half-press of shutter button. Not to everybody's liking but it is to mine.
File names: First 4 characters are something that identifies the specific camera. I do not want the possibility of a file name being the same as one taken with another of my cameras.
RAW format: DNG. It's more widely recognised than PEF.
