Photography Question

How many megs?


At what megapxels would the human I not be able to distinquish the difference in quality of photos? I would like to purchase a digital camera but I have no idea of what to expect from resolution. At what pixals or resolution can I make certian size photos, 5X7, 8X10, etc. I am looking at 4 meg and 5 meg cameras. Is there that much difference between the picture quality?

  Donnie, anything over 4 is supposed to make a gook 8x10. I just purchased a Nikon D100 6.1 Meg. The pics are beautiful even at 11x14. I wouldn't trade it for the world, it was well worth the investment, and gives me the same versatility as my old canon slr. I shot everything on manual so I really haven't used the auto modes, and I do mostly portrait work, but people are shocked when they find out it is digital printed with an Epson 1280, no one so far has been able to tell the difference between my prints and the ones processed from film.

Here is an image shot with the D100 if it looks a little distorted I'm sorry I don't usually upload photos. This is my 6 year old with no front teeth. "All I want for Christmas"

Sorry I don't really upload well, I'm going to try this one more time, If it dosn't work just believe me when I say at 11x14 the only thing I wish I had done was steam my background a little better (you can see the wrinkles I left)

  The simplest solution is to take the pixel dimensions of the camera in question and divide the two numbers by the dpi requirement of the output device.

For example, if your camera has the pixel dimensions of 3000 x 2000 and the output device you are printing from requires 200 dpi to produce "photographic reality", divide each of the two numbers by 200 to get the optimum size print that file can produce. In the case of 3000 X 2000 we get 15 X 10.

The number 200 is an arbitrary choice in this example. Many printers/output devices require less while some require more.

  Thanks. All the info has helped considerably. Next question. Which way is the best to go? I have been looking at the Canon G2 or G3 and the Nokon Coolpix 5000 or 5700. Should I go this route,which would keep me around or a little under the $1000 dollar mark or would it be more beneficial to go with the Canon D60 or Nikon D100? What I am really asking is do I gain that much by going with the higher end SLRs or not?

  The primary advantage with the higher end digital cameras is the capability of using that products wide assortment of lenses.

The primary disadvantage is the increased cost.

  My advice is go with the D60 or D100 for the wide assortment of lenses,flash units, filters, and your own creativity, yes it doubles the cost, but are you looking for a cheaper camera,or one you will be happy with for a long long time? I wish I could upload my pictures for you, but look at the difference in the way the cameras look and feel, thats what really made my discission easier. I went with quality.

  The only thing I don not like about the high end SLRs is that there is no preview available in the LCD before taking the picture. Of course you can always erase or delete the picture afterwards. Should this be a concern?

  It's not an issue for me, but I went from 35mm to digital, I may be old fashion, but I like to depend on what I see in the view finder. I have never seen an LCD screen I could depend on. You have to look at them at just the right angle because of glare, I just wouldn't want to frame a shot that way.

  Donnie,
Have you bought a digital yet? It is after Christmas and I just purchased a Canon G2 from BHPhotoVideo.com, in the "used dept" for $469 (as of 12/30/2002). Being a very reputable online retailer, they guaranteed it is in "new" condition but they can't sell it as new as it was a display model. Also, everything "as new" is included in retail box.
OR, what did you end up with.

  Tony again. After receiving the G2 ordered above, it was in A++ condition. Like "new" with all accessories, software, etc. I love it and for the price, can't be beat.

  Tony,
Still have'nt venture into the digital world. I have dicided to wait until the PMA this year and see what new cameras are announced. If Canon announces a D90 or something equivalant it may drive the price of the D60 down some and since I have an EOS system started I believe this would be of interest to me. If not I have been looking at the Sony 717 even though I don't like the memory stick being the only storage device for it. The G2 at $469 seems to be a real deal. I like the G2 but was hoping to break the 5 MP limit on my purchase. I don't Know yet. I hope you enjoy the G2. Let me know how it turns out.

  Donnie,
You've got the right idea to wait on the PMA. Since you have the lenses, I'd wait for a price difference too.
Good luck.
