In the end I was able to take the test this weekend. I did the test for the following magnifications (approx.): 0.70 / 0.80 / 0.90 / 1.00 / 1.15 /
As a summary: for 1X or smaller increases, my Coolscan 8000 is better in direct mode than in reverse.
1.15X is the only case that gives a better image quality in reverse mode than in direct mode. It matches Lou's assessment:
In the central area the differences are practically negligible. On the other hand, the difference can be seen in the edges of the images.Lou wrote:The two magnifications being discussed here, 0.9x and 1.12x, are very close but are on opposite sides of the 1:1 mark, so it makes sense that the best orientation for 0.9x is the reverse of the best orientation at 1.12x.
I enclose the summary images. From left to right:
0.70 / 0.82 / 0.90 / 1.00 / 1.15
The direct mode corresponds to the upper crops.
What I do observe is, in direct mode, a small increase in glare at lower magnifications.
