How does exposure latitude compare between digital and film?

7) The tested film has higher exposure latitude and higher dynamic range than the in-camera jpeg images. 8) Film versus raw digital: Film degrades color and increases noise as the film saturates. While the film does not saturate as fast as digital, it degrades faster at the low end.

What is exposure latitude film?

Exposure latitude is the extent to which a light-sensitive material can be overexposed or underexposed and still achieve an acceptable result. This measure is used for digital and analogue processes, e.g. optical microlithography or photography.

Does film have a higher dynamic range than digital?

A release by Kodak showcased that most film has around 13 stops of dynamic range. Today’s modern digital cameras all average around 14 stops of dynamic range, with high-end units such as the Nikon D810 reaching almost 15 stops.

What is latitude in digital radiography?

The latitude (or dynamic range) is the range of receptor exposures over which an image and contrast will be formed. The relationship between receptor exposure and the resulting film density is usually described by the film characteristic (or H & D) curve as we see here.

How many stops of latitude does film have?

The dynamic range of film is the ratio between the largest and smallest values of light intensity that the film can handle. Most negative film has around 13 stops of dynamic range. A stop is the doubling of the light intensity. This means that the highest brightness it can handle is 8192 times the lowest it can handle.

What is latitude in radiography?

Radiographic latitude refers to the range of material thickness that can be imaged This means that more areas of different thicknesses will be visible in the image.

Why does film and digital look different?

The biggest reason the results look different is the highlights. We’re used to the way film looks. It overloads gracefully when things get too light or wash out. This mimics our eye far better than digital.

Why does film look better than digital?

Film captures photos at higher resolution than most digital cameras. Analog film can be pushed or pulled multiple stops when needed, but the amount of contrast within the image is affected.

Is film higher quality than digital?

How does digital radiography differ from film?

Digital X-rays are like the digital cameras we have today. They still use X-rays as the standard X-rays; the only difference is that their sensors are connected to a computer and not a film. This enables the modern X-ray to capture clearer and more accurate images as compared to its predecessor.

What is image latitude?
