Courses In Digital Photography

Calling all camera buffs: Why is 35mm the standard size in digital professional photography...?

I realise that it was standard in analogue - but thinking about it - digital is a completely different format where anything goes - No?

It would seem the standards in analogue photography have been passed over to digital photography as a matter of course but the physics of digital photography is completely different to analogue photography - is it not?

How does pixel size on a digital sensor relate to film capture on a traditional roll of film?

Who decided these specifications?

I have tried to google it but can't find an explanation.

Thanks in advance.

The explanation is that in the beginning, technology could not produce a sensor to match the 36 x 24 mm frame size of a 35 mm camera, yet all the dSLR's were based upon the design (and in the beginning) and actual 35 mm body shells.

It took nearly ten years from the introduction of a dSLR to develop a viable full frame dSLR. The benefit of using the same format as a 35 mm frame includes 1) all traditional downstream equipment and image distribution was based upon the 36 x 24 mm format, 2) the larger the sensor, the higher quality digital image can be created and 3) legacy lenses and accessories were still viable.

There is really a huge benefit when long established technology can be transferred into the new technology. The users of the old and new technology can directly transfer their skills to the new technology and the cost of converting to digital from film is somewhat reduced

There is no difference in the way light is transmitted and focused on the film or sensor plane. In fact, the process of creating images where saved on film or to a memory card is all analog until the image is processed through the analog to digital converter in the digital camera

Until five years ago, the quality of the images created by digital cameras could not compete with film. Now with larger pixels, better image processing (resulting in low noise at high ISO's) and more sophisticated post processing programs, digital (dSLR's) have become adept at meeting or exceeding the image quality of film.

Try this with film.

There is NO 3200 ISO colour film and if there were, the grain would be quite course when compared with this digital image. You will notice that there is very little noise in the image. This is something that was rare, five years ago
