I heard someone say that 8Mp digital cameras were the equivalent to 35mm film quality? Does this mean they have the theoretical equivalent resolution? Are they the equivalent to 35mm? As digital has no 'grain' per se, they do produce very clean images up to about 15 x 10 (inches). Film resolves higher than an 8 mpix sensor. However it is noisier than a digital image. Decent prints up to about 24 x 16 are quite possible. I recently finished some scans from Kodachrome 25 for a friend. Considering the slow film and the shots are handheld, the detail is very good. The scans are 7256 x 4880 ( 35 MPix) (so a print at 300 dpi will work out to about 24x36) which is how he's ordering the prints for 3 of them. I'm sure an 8 Mpix would not do nearly as well... and if my friend had used a tripod, well...

They are in the same range today. I still give most film an edge at
8MP. The quality of an image from a high quality camera vs a low quality one will not be equal nor will images from the best 35mm film - camera combination equal the quality of the worse. The ranges overlap. In addition you are really talking apples and oranges so there can not be a direct comparison. -- Joseph E. Meehan 26 + 6 = 1 It's Irish Math "Matt" wrote in message ...

35mm is a size - 35mm is 35mm. 6MP is considered approximately equivalent, so 8MP probably exceeds 35mm in terms of resolution. Not slow slide film it doesn't, but image quality is about a lot more than resolution. |

Trying to be funny when it obviously isn't your forté if that post is
anything to go by. Yep...as far as "being funny" he will have to get by on his looks. |

From: "Matt" I heard someone say that 8Mp digital cameras were the equivalent to 35mm film quality? A dSLR like the Canon 1D Mark II with 8 Mpixels and a large sensor seems to produce better large prints for me than ASA 100 speed Provia 100 F or Velvia scanned with a 4,000 dpi scanner. I'm getting 16x20" prints from the 1D that are better than any prints that size I've gotten with even Velvia 50. But 8 Mpix from a smaller sensor camera might give different results, so "it depends" on where the 8 Mpixels came from and what kind of film you are using for your comparison. Does this mean they have the theoretical equivalent resolution? No, fine grained film still does better at resolving lines on test targets, yet the digital prints look better ... how? Because of the lack of apparent grain. Digital simply blows up better than film. Are they the equivalent to 35mm? Download some Mark II sample images from the Canon site and resize them carefully and print them to see for yourself, though these jpegs aren't as smooth as RAW file conversions. Where does the 16.7MP full frame Canon EOS1Ds Mk II fit into this discussion? |
