    Don't hate the tool for being easy to use. Digital photography has a great deal of promise, and there are plenty of gifted photographers using such cameras... Give them a gigapixel camera and I'm sure they'll astound us.

    I agree, unfortunately, I have also seen a decline in the quality of photography from people we have worked with before in film. I give these peole more benefit of the doubt as, I know they can produce better work, I am just assuming that they are new to the digital medium. Still frustrating though.

    Meanwhile, I just want a CCD with enough real eastate that I can not only really piss off, but actually cause a purist to break down in tears by saving to JPEG ;-)

    well, JPEG doesn't scare me. As long as it is only used once. After much testing, you can't see the difference in print of a high resolution eps file and a high resolution jpg (med. high and up quality). The problem comes from people that open their jpeg, work the file, then save it as a jpeg again. Changes how the file is compressed, and looks like poo poo(technical term).

    I'm a little confused by some of the aritmetic. It looks like you multipled 19 square inches by a linear 2400 dpi.

    He was referring to two seperate things. The area is only relevant in that it gives you an indication of what the file size will be. dpi or ppi (same thing dots or pixels, dot's is a carry over from screen printing) is the indicator of how much information is in a particular amount of space, and his 19 square inches is an attempt to give an idea of area, so the total number of pixels is 2400 (dpi hz) x 2400 (dpi vrt) = 5760000 pixels per square inch. Which is a useless number, because you now need to multiply that number by 19, and now you have the somewhat useless fact that there is 109440000 pixels in a 4x5 transparency, whoops, forgot to multiply that number by 3 (Red Green Blue channels), 328320000.

    Anyways, all of that is rediculously cumbersome, so, we have the tendancy to report the size, ppi, and color depth (RGB, CMYK, LaB) which let's you know after some time in the industry, aproximately how big a file will be in megabytes.

    Aside from that, I think people spend too much time worrying about resolution and not enough about bit depth.

    Mostly that is because most people who are dealing with this stuff are outputting to print. Followed by movies. Followed by (a ditant third) photographers (think art not commercial). And they are mostly concerned with reproducing the color spaces that they deal with.

    Here is a color space chart that shows the box within a box within a box that is human created color in relation to visible light.

    Personally, I'd much rather look at projected slides than print.

    The primary reason, though, would simply be that photographers are using digital cameras in many places where they work quite well, and they would like them to eventually be the primary workhorse for most photographic needs.

    I spend all day retouching photo's from these photographers. At this point I am of two minds over this. On one hand I like the fact that digital photos end up needing more work done to them than from a transparency. (People really miss film grain, and the colors are always not what the photographer expects). Every 6-8 months we start getting larger files, but not any better quality wise.

    On the other hand, since digital photography has gotten so wide spread I am seeing much more "bad" photography. The lighting sucks and you can tell the ad agency went with some cut rate photgrapher who doesn't understand the concept of an F stop. While this also means more work for me, it is really frustrating to fix the same damn thing again and again because the photographer doesn't understand the concept of his chosen profession. But hey, he can take 500 shots to get that one image his client actually likes.

    Probably the simplest artifact in common use is the knife. Yet given our resources and technology, it's appalling what passes for a knife in most people's kitchens.

    More oftne than not though, this is not out of the knife making industry's fault as a whole, it is the knife owners inability to justify spending the money for a "good" knife. The same could be said for a hammer, I had an ex-gf who routinely used a high heel shoe to hammer in nails for picture frames. When asked why she did not just buy a hammer, the response was, "this works why should I spend the money?". I had no response to that, I mean, ti's not like she was building something structural, her only use was hanging up pictures, so she did not need a real hammer (her logic not mine) If the simplest artifacts still have such problems after thousands of years of refinement, what can we reasonably expect from the newest and most complex artifacts ever created?

    I would say that the "simplest artifacts" are about as refined as they are going to get. Hammer, lever (crowbar), wheel, pulley, ramp, etc. What changes in these is usually just materials science. A hammer made out of pig iron will hammer a nail as well, if not better in some ways than some exotic blended iron. However it will not be as light or easy to use as the new one. The task at hand though, placing a nail into wood, is accomplished the same.

    Computers on the other hand are so new as to be laughable from a "devlopment" standpoint. Many people are still trying to figure out WHAT to do with computers, let alone HOW to do it. So, simplicity becomes more important. Which leads back around to good UI. Computers allow you to "do" jusst about anything, as long as that anything is digitaly controlled. ie: I can design a hammer on my computer, but I will need more equipment to get my computer to use the hammer it has designed. For instance, my mom uses her computer for e-mail, the web, writing physical letters, and storing her digital photos. That's it. I set her up with a powerbook, and that is STILL overwhelming to her. I however, do lot's of graphics work, and am constenly looking for ways to automate and tweak the interface to my tastes. Yet we are both using the exact same tool (in this case a mac).

    From all of this I have read, here are the steps to fool this process.

    1-Manipulate image, smooth any areas with disparaging noise 2-New layer, set layer to overlay fill with 50% grey.
    3-Filter ->add noise (pixel ratio based on image resoltuion)
    3-Filter->Gaussian Blur (usually .2-.7 pixels)
    4-Curves endpoints in 10% top and bottom
    5-Filter->noise half what you did before
    6-Filter G. Blur again

    This should give you a realistic looking film grain (settings vary based on image resolution) with practice you can match a film grain from a supplied image. By creating it on a layer, you can then brush it in on your comped image to family the various bits together, and as it adds some irregularities that appear random, it would probably fool the software

    Print it on a high quality printer

    The short answer is dot structure. All printers, (excepting Dye Sub) use some form of sparying of ink, or layering of screened images(halftone dots) Fancier does not necessarily mean smaller dots, it usually means more calibrateable and more consistent color. What you need is a film recorder, which will transfer your image to a negative or a slide, and currently, there are no digital cameras that will record an image at a high enough resolution for this to be flawless (about 40-100 pixels per millimeter), so you must start with a film camera and scan the image in at a high enough resolution. The typical rule of thumb for this kind of work would be one size up from what your end result would be. So if I wanted to create a faked 35mm slide, I would start by taking pictures with a 4x5" film camera scan and use that.

    But yes, your point is sound. Technology will not fill the analog hole. Even in "digital" photography.
