Medium format advantages
When image is everything, bigger is always better. The 21st century imaging world is awash with pixels on popular mass-produced capture devices from smartphones to DSLRs. And they do a good job – within defined boundaries of expectation.
In these circumstances there is a commercial imperative to see the bigger picture and embrace the bigger pixel solution.
If you are a quality-fixated photographer working at the top of your game for perfection-driven clients or on personal projects that serve to both underpin and promote your own unique craft and creativity, then there is never going to be room for compromise when it comes to equipment.
What is medium format?
Medium format historically refers to the 120 size film format that was used in the Hasselblad V System cameras.
It was much larger than the standard 35mm format and offered a superior image quality thanks to the high quality lenses and the larger image area of the film.
In digital photography, medium format refers either to cameras adapted from medium format film models or to cameras making use of sensors larger than that of a 35mm film frame.
Medium Format Sensors
Not Just Megapixels
Even though our sensors offer some of the highest pixel count available today, it’s not just the density of megapixels that sets a Hasselblad image apart from the crowd. For any camera sensor, the physical size of its pixels governs the amount of light recorded for each one. Most sensor manufacturers are now using micro lenses on their pixels to maximise the light collected and the light gathering power determines the dynamic range of the sensor.
Pixel size and noise level drive the available dynamic range and very simple natural colour solution that delivers accurate colour recordings regardless of the situation and smooth tonal transitions without any need for multiple colour profiles.
Hasselblad’s 50MP CMOS sensor delivers a pixel size of 5.3 microns; a similar resolution DSLR would have a pixel size of around 4.14 microns, giving the Hasselblad a 64% increase in light gathering power.
Wide Dynamic Range
Dynamic range can be described as the tonal ratio difference between pure black and pure white. To put this into perspective, the human eye can perceive a dynamic range of around 22 stops; most digital cameras fall far short of this value.
In the photographic world, this means starting from a black exposure with no light hitting the sensor – how many stops you can increase the light level whilst still showing a signal level that is not pure white.
The Pixel Analogy
Imagine each pixel as a container. The larger the container, the stronger the signal it can hold. In addition, all digital camera sensors have a minimum sensitivity level they can use, set by the electrical noise of the sensor itself. The difference between the two is known as the signal to noise ratio.
Our medium format sensors have a very high signal to noise ratio.
When you combine this high quality signal to noise ratio and the larger pixel sizes, Hasselblad sensors can deliver up to 15 stops of dynamic range compared to around 12 stops on a smaller sensor DSLR.
Pixel size and noise level drive the available dynamic range and very simple natural colour solution that delivers accurate colour recordings regardless of situation and smooth tonal transitions without any need for multiple colour profiles.
