    Welcome Tim

    I've wondered if lenses can resolve enough to give either an advantage. Suppose you have a 200 megapixel camera and the best lens can only resolve 60 megapixels. When will digital reach the limits of lens resolution, and will it be that much higher than film (which I believe may have already reached this point). I recall someone saying an 8x10 negative has well over 2 billion "pixels", I think that will keep me going for a while, and no need to worry about data integrity of 5gig image files.

    well a lense for digital is basicly the same as a lense for analog. the key diffrence between them is the medium where the image is captured. For analog this is Film. For digital it is a CCD (Charged Cuppled Device.)

    Edit: Ah... Mom just informed me of an article that tells how digital lenses are not as good as analog lenses because the CCD cant capture that dense an image. This makes sense to me. It lowers the total cost for the camera by useing a lower quality lens.

    Current CCD chips are tiny compared to a negative which i find odd. Wouldnt it be more advantageous to focus the image on a much larger area but keep the pixel density? One would think so.

    One interesting tidbit ive found working with digital video, Pixel Shapes.

    One would assume that a pixel is square in all forms. However on NTSC televisions they are ever so slightly rectangular. And in other contries... well thy run the gammot from square to a really exagerated rectangle. Computer screens are square across the board.

    First, wellcome onboard.

    It's a matter of price.
    Silicon prices skyrocket with size (since you're kind of a computer geek, for sure you know CPU manufacturers try their hardest to keep chip area as small as possible).

    So, there's a very real price barrier in digital - small CCD's won't have the same quality of large CCD's; large CCD's are VERY expensive.

    Welcome,

    I have a few friends at Industrial Light and Magic. If you are interested in digital moviemaking etc, and need any sort of "in" I might be able to help you.

    1. Digital is superior for the strictly snapshot photo. IF you want something quick and dirty its the way to go.
    2. Color Digital photography is on the level of color Analog photography. Its just alot of expense up front.
    3. Black and white Analog is superior to Digital at this time. However This does not mean that digital wont improve. Look at how fast Analog is inovateing with new technology, now look how fast digital is advanceing.

    This is singular. Does she mean to imply that there is only one?

    1. No argument. Perhaps a little more accurate to reverse descriptions: First "Dirty" and then (secondarily), "quick".

    2. Nah. I don't think, attribute compared to attribute, that "digital" is anywhere near, at least not yet. There is a *vast* difference when compared, highest level of chemical color print, to highest level of "digital" print. Don't be fooled by "One-Hour-Lab" analog color prints. The *best* "Custom Printed" color analog prints are seldom seen outside of galleries - and to tell the truth, they are not all that common *IN* the galleries.

    3. I don't really see that much "improvement" in analog black and white prints. IMHO, they were awfully damned good to start with, and an exceedingly "high standard" for "digital" to reach.

    It's time he learns the true meaning of the dark slide. Together as Mother and Son, you can bring order to the photographic world!

    *Shudders* Grammar Nazi..... Ugg....

    I was probably overzealus on comparison between Collor Digi and Color Wet. I just saw tonight a Color Print by one of moms friends that i really liked. This wasant something you could get out of 1hourphoto booths.

    When i talk about Improvement i didnt refrence the existing level of quality against each other. Analog done right is superior to Digital, no questions asked. I merely apply Moores law to digi cameras and watch as they get better and better. They are STILL handicapped by phisical limitations but like all pieces of technology, they will improve.

    I sense a disturbance in the Fix. As if a thousand prints suddenly cried out in pain and then were washed. :P

    *New Stuff*

    Mom shows me prints that she gets from people and im amazed at how clear they are. I can tell a 35mm negative apart from a larger negative based upon just looking at the size of grain. She got one this summer and DAM that looks good. The guys name i cant spell or pronounce right but it sounds spanish? Les sent her a BEAUTIFUL print....

    I do Flash Webdesign for people, So if you would like me to make a gallery like thing to display on a website that includes buttons and sounds and all sorts of niceities that just add to the experience, im willing to do it for you. I can make em better than the photoshop autopilot thing. Just Send me a PM or Email.
