Dynamic Range of Digital Cameras

I was reading recently an article that stated a digital cameras’ sensor is more like slide film; meaning, the latitude of digital photography is very low. (There is very little that separates proper exposure and overexposure). I did some calculations with my own camera, a Nikon D50, and found about 7.5 stops range. While I heard black and white film has 14 stops. My question is, what is the best way to replicate the latitude of black and white film? Is HDR the only way to approach film? I’ve heard good things about the DR of the Fuji S3 and S5 Pro, but was wondering if there were any other cameras with a better DR. Any comments would help. Thanks.
Don’t know who is giving the thumbs down.

Indeed this can all be a little confusing..

While mono film images have a higher dynamic range, the curved [rather than linear digital] response of film tends to compress the dynamic range of the photo so it is viewable by the standard media. For instance, if you had a digital camera with a 14 stop linear response, there would not be a printer or monitor capable of displaying even half the information in the photo.. the contrast and clipping would be far too great to view. Your test with your D50 may be inconclusive [depending how you conducted your test] as you may have been measuring the dynamic range of your monitor ..which is almost certainly less than the image sensor. Its comparable to judging the sound quality of a recording through speakers incapable of producing all the frequency range ..you are limited by the weakest link in the chain.

The curved response is to some extent simulated by the S5 pro making it ideal for simulating black and white film. This curve means that the bright areas of the image are recorded with a lower sensitivity thus allowing the detail of up to 14 stops [in theory] to be compressed to a picture of something like half that dynamic range. Therefore the curved response of film can be compared [although the results can differ greatly] to the tonemapping process of hdr. A non-tonemapped hdr image could easily reach 14 stops of information but this is useless as all viewing media again is far less. This compression process is something that will become more widespread in the digital world in the coming years both in cameras and software form.. for example there may be a hdr tonemapping algorithm specifically designed to emulate the b&w film curve. For now it seems Fuji are the market leaders in this area.. but there is the limitation of the 6mp actual megapixels from the S5 pro.. even though it outputs files at 12mp.

Problems following a photoshop article in popular photography magazine?

I used an article in the Jan. 2008 issue of pop photo titled “4 ways to save a face.” The 1st time I used it, it worked great, but now I am having problems with the 1st part of the article titled “All-Over skin Smoothing.” Instead of bluring the skin and smoothing the skin, it makes black streaks. This only happens on some of the pictures, or it works only on certain people in the images. These are the directions the magazine gives: 1)Duplicate your background layer by going to Layler>Duplicate Layer. Name it Blur. 2)Go to Filter>Blur>Gaussian Blur. Set the radius to 50, and click ok. 3)Add a black layer mask to the Blur layer. Holding down the Alt key(Option on a Mac), click the Layer Mask button. 4)Hit B for the brush tool. In the options bar, pick a medium-sized brush, and slide the brush’s opacity down to 30%. Be sure that white is set as your foreground color and paint your subject’s skin until it looks smooth and glowing. Any advise on what I am doing wrong?

Not all faces are just right for these settings. You may have to use less blur or a smaller radius for some and more of each for others. Then, play with the opacity on the blurred layer until you like the result. You may not even need to use the white brush.

makes use Canon EOS Elan II infrared to align the holes in the film for the film advance automatically?

or other words, Has anyone used the Canon EOS Elan II in white (or color for that matter) infrared photography and black? I was reading this article on http://www.kenrockwell.com/tech/ir.htm kenrockwell.com and said: "Most Canon cameras do this, I'm sorry" for the IR beams used in the camera …. ideas?

Yes does, but is not usually a problem. I used this camera with two films and Ilford SFX Konica 720nm IR film without problems. The condensation on the infrared sensor limited to the area of the sprocket holes. Others have used different IR films.
