Yep, I'm that kind of photographer, slides, color transparencies is my practice, sometime developed like this, in positive E-6 chemicals, and sometimes, more often, developed in C-41 chemicals, to get a weird color negative.

And what I was fearing has happened : the first 10 pictures, taken with too much light for the f/16 aperture, are completely overexposed and blurry.

I augmented the contrast when developing the raw file, but there's not much to see.

Blurry and overexposed.

I should be more careful with the below, but that picture points a suspected trouble : the inner color of the below isn't as black as the outside, It's bluish, dark, but not black, I need to paint it black (as some other things to avoid parasitic reflections).

Ok, the ones shot later are much better, still a trouble with the below, but the lens looks good, event if it's a little blurry due to the opening of the film holder blind, the exposure is good and the details look sharp.

A 100 % crop of the previous image (this is not a real digitalisation of the picture, just a handheld shot) gives me good feeling about the results, the lights are not too burned, and it seems to have a good micro contrast, looking at it with a good magnifier is not the same sensation than on screen, its more detailed.

Well, I can continue the experiment, it is not a « cul de bouteille » (French for very bad optic), but now, I need to build a shutter.
