Just because technology can do something, doent meant its always right
PlainName:
Used to be a good brand. Still got my last CRT which is Iiyama, although it's not been used for loong while now.
bd139:
I’ve got another Iiyama in the cupboard which is my emergency PC debugging monitor. That’s a 24” VA panel and seems ok still. It’s about 3 years old now. I can’t use it as a desktop monitor any more. It’s horrible :-DD
SiliconWizard:
I still have a 23" Samsung that I use on a regular basis. It's from 2009. Still works as good as new. Not a single dead pixel, no issue with the backlight. Nothing.
I once had a IIyama CRT, which was good but only lasted like 2 years.

Why didn't anyone tell me this before I bought mine? Seems you all knew!

Slide film is known to be quite finicky regarding exposure, because the usable range is quite small compared to negative film. Also, the density range is not that important, you can influence that with the developer used, time and temperature anyway, the usable exposure range is what defines dynamic range.

I picked Ektachrome precisely because there's no wiggle room, it always goes through E6 chemistry (unless you're one of the weirdos putting it through C-41 to get funky 'art' rather than accurate reproduction.). Otherwise some bright spark was going to argue about the minutiae of the chemistry used rather than the broad principle. The widest dynamic range you'll get out of any silver emulsion is somewhere between 1000:1 and 10000:1, limited by a Dmax on the close order of 4.0 for continuous tone images (i.e. no fair citing lith film used in strictly black or white processes where Dmax is limited by how much silver you can afford).

Yes, but, again, Dmax is not really an important figure when it comes to dynamic range. It's conveniently crafted to match the output medium. Negative film has a wide exposure latitude, but conveniently it is less dense than e.g. slide film. It maps a wide input range to a smaller output range and that's just a better match for photographic paper. So, even if the density ratio is just 1000:1, you can still have 14 stops of dynamic range, and that's quite good even by todays "digital" standards.
