Why don't you just switch to digital?

hazy lens...sticky shutter..but still makes an image...crap quality only in the eyes of the beholder ;)

I know what you mean. Optical aberrations, light leaks, guessing exposure, trying different films, feeling the life of a mechanical camera on pressing the shutter button, messing around with chemicals, seeing wonderful results whether planned or by accident. Whenever I'm asked why not switch to digital?", I have to ask "What, and miss out on all the fun?"

I'd like to suggest that, instead of the teeth-grindingly awful "analog(ue)" those of us who genuinely enjoy using film adopt instead the more appropriarte term "artisanal" - like baking bread, we get our hands on fun by being an integral part of a gloriously chemical process, working directly and intimately with the raw materials to achieve the desired end result from the sweat of our own brow.

 

Just a thought... :D

Not unless you coat your own plates.:D

Film is Caravaggio. Digital is Norman Rockwell.

 

:eek:

 

(I had NO idea what I was stepping into. I feel like I lit up a cigarette in a 3 pack a day former smokers house)

 

I wouldn't take my sig too seriously if I were you - in any case, maybe you prefer Norman Rockwell to Caravaggio?

 

I shoot both film and digital (I actually work with digital media), and there are times when that clinical, rather boring Rockwell look is the one you want. ;)

Real film photographers mine their own silver and make their own gelatin. The rest of you are just phonies!

I think "Chemical Photography" is a good description of the process, at least that is what I prefer to call the film/developing/printing process.

 

Film emulsions are digital/binary to the the extent that each film grain is either "on" or "off", film most certainly is not analog(ue).

 

WRT "chemical" I recall quite a few cases of pollution of rivers by film manufacturers/developers - less problematic in recent times for obvious reasons. Still I will (also) use film as long as it is available.

 

Baking my own bread again is on my to do list and in that case "artisanal" sounds about right.

This is completely and utterly WRONG. Film grain is absolutely not 'on' or 'off'. Read the following blog post.

I'm frankly sick and tired of seeing this lie bandied about - even printed by a so-called 'expert' in LFI. It's totally incorrect.

From the article:

"Film emulsions are generally Ag/Br/I atoms combined into crystals from about 1 - 10 microns in size which are stacked in layers and dispersed randomly throughout the emulsion. They contain millions of atoms and many sensitivity specks which consist of sulfur and gold."

 

Gold?

Gold?

 

Are you questioning the science, the research or the conclusion of the blogpost? Do you think that film is binary? Is a film grain only 'on' or 'off'? If you have an issue with the chemistry in the blogpost then I'm willing to hear it, but the author would be a better and more qualified person to discuss with (he used to post here, but for some obscure reason he no longer bothers).

 

Let me know.

I think he's questioning how much gold there is in film emulsion.

 

Questioning the accuracy of the blog by Pico's sort of post strikes me as underhand. If there's an issue with the accuracy of the science, then the straight thing to do is get in touch with the author imho. And by all means report the correct information here.

 

If he wants to contradict the point that I was making, then I'm more than willing to stand up for my contention that film grain is absolutely not binary.

IF there is no gold in film emulsion (if there is, that's the first time I have ever heard of it), then one has to question the accuracy of the rest of the blog, surely?

 

I am sure that Pico can answer for himself, but that's what it looks like he is questioning to me.

Location of latent image

 

Depending on the silver halide crystal, the latent image may be formed inside or outside of the crystal. Depending on where the LI is formed, the photographic properties and the response to developer vary. Current emulsion technology allows very precise manipulation of this factor by a number of ways.

Each emulsion has a place within each crystal where LI's are formed preferentially. They are called "sensitivity centers." Emulsions that form LI in the interior are called internal(ly) sensitive emulsions, and those that form LI on the surface are called surface sensitive emulsions. The sensitivity type largely reflects the site of very shallow electron traps that form latent images effectively.

Most, if not all, old technology negative film emulsions had many unintentionally created edge dislocation sites (and other crystalline defects) internally and sulfur sensitization was performed on the surface of the crystal. Because multiple sensitivity centers are present, the emulsion had both internal and surface sensitivity. That is, photoelectrons may migrate to one of many sensitivity centers. In order to exploit the maximum sensitivity of such emulsions, it is generally considered that the developer must have some silver halide solvent action to make the internal latent image sites accessible. Many modern negative emulsions introduce a layer just under the crystal surface where a sufficient number of edge dislocation is intentionally created, while maintaining the bulk of the crystal interior defect-free. Chemical sensitization (e.g., sulfur plus gold sensitization) is applied on the surface. As a result, the photoelectrons are concentrated to a few sensitivity sites on or very near the crystal surface, thereby greatly enhancing the efficiency with which the latent image is produced.
