Old & New: variation on Idea #2 - Second Attempt

The "Old & New" meeting of my camera group is fast approaching so I thought I'd have another go at the in camera multiple exposure I did on 11th January. This time I played with the lighting to reduce the shadows and changed both the magnification and the exposure between shots to reduce the dominance of the print and the calculator compared with the more delicate markings on the slide rule. Also fiddled with the composition, after studying the previous ones. Seems better this time. It's the result of 5 shots, blended in dark mode by the Z50.
