Dmax Tr

Most people prefer slides. This is without any good basis as far as I'm concerned, but I doubt if I am going to convince anyone of that. Slide film is designed to produce relatively high densities in the film because of the way it is viewed. If one overexposes even slightly that will excacerbate the situation. In such cases, the densities in the shadows will exceed what many moderate priced scanners can handle. For example, Epson says my 3200 scanner has a dmax of 3.4. I use Vuescan which allows me to read the actual densities as well as the usual RGB values. I'm not sure these are the same as would be read by a precision densitometer, but they seem pretty consistent with what I would expect from years of experience with film of all sorts. My slides often have maximum densities of 3.0 or higher, but not beyond 3.4. Thus from my perspective, Epson's advertised value is accurate. I don't usually have any trouble with the scans from those slides. But I'm very careful about exposure.
For slides, I readily sacrifice the shadows if necessary in order to get proper exposure for the highlights. That is the conventional view of how reversal film should be used. One should avoid scenes with extreme contrasts and if that can't be avoided, concentrate on getting the highlights and midrage properly exposed, which means one may lose some detail in the shadows. But if one uses slide film with the intention of scanning, there is an additional option. One may overexpose somewhat, thus preserving both highlight and shadow detail. (One can't overdo this since slide films tend to have limited latitude for exposure.) The resulting slide won't be ideal for direct viewing, but when scanned, if the scanner has a high dmax, one may produce a scan with adequate detail at all levels. A scanner like the Epson 3200 may not be adequate for such slides.
Ive just had my isuzu dmax 2016 plate converted to a tipper and when i went to pick it up a major fault has developed and I cannot get out of 4 wheel drive. The circle electronic dial changes between 4 low and 4 high fine but when i turn it to 2 wheel drive it whirs and you can hear it trying to change to 2 wheel drive but it doesnts. It whirs again and on the dash it changes to 4 low drive. This is doing my head in, is this something that anyone knows anything about? Could it be something to do with the earth from the tipper ram of the alterations in wiring that have gone on to the rear lights with the tipper body being put on? Or has it somehow got stuck as its been sat for a month and a half???
