parasite images

I had clicked on the link you provided in the mid of the night but could not resist to watch the whole video (tired now

My favorite term turned out to be 'parasite images'.
Fascinating to go back in history...

Btw, what about 'uniform pre-exposure' - is that somehow related to UniWB?

Wonderful presentation!!! I was glued to it for the 65 mins that it runs. Answered so many things bouncing around in my brain.

Interesting to learn that the first HDR print was done in 1858 using 5 glass negatives cut to fit into 1 print. To see example of Ansel Adams, Moonrise over Hernandez, print before and after he applied HDR in printing in reverse. Not to mention all of the light bouncing around inside camera lenses and bodies.
Any others like this you would recommend Iliah?

ps - well what would reaction would you expect from a physicist and engineer ??

Re: parasite images

Btw, what about 'uniform pre-exposure'

The name refers to a group of (rather well-known) methods used to increase the film sensitivity and lower its contrast. In its simplest form the exposure during pre-exposure is usually to Zone I in Adams scale.

Re: First lecture in a long time that I've rather enjoyed...

Same here. Watched it two times yesterday. Interesting that with direct light projection onto the negative film I can easily get 14 stops of gradations, but only 12 if I measure them directly behind the lens with a spotmeter.

This one is rather unique in many ways.

ps - well what would reaction would you expect from a physicist and
engineer ??

Two things worth mentioning IMHO - the art of dispelling myths in a non confrontational manner, skipping bold statements; and avoiding presenting verification data in the way that it goes nearly unnoticed.

Great Iliah

Dear Iliah,

Beauty is in the eye of the beholder, as they say.

So much money going into battleship cameras and "great" expensives lenses for pasting some shots in the web (smallish in size to make it worse) to be seen in normally not calibrated monitors. So much fighting over the comparison of this lens against the other.

How few printing large and using the "knowledge" of the art.

What a waste!

It amazes me what interesting serious material can now be found in youtube.

Thanks again.

With very kind regards,

Raul

Yeah, that is interesting. Do your different lenses fluctuate much from this 12 stops, or is that a typical approximation?

thanks, Iliah

This is interesting and something I'll need to revisit a couple of times.
