Bronica Learning Center :: Why Use Medium Format
When is
bigger better? Often we have to make compromises. The ideal is to optimize the
resources that we have to achieve the maximum results possible. Medium format
is a compromise in negative size compared to large format negatives; however,
by giving the photographer the ability to change finders, choose different
backs and change film mid-roll, the flexibility and creativity of hotographing
can be enhanced.
Once someone is interested in medium format, they must make the decision on whether they want a 6x4.5, 6x6 or 6x7 system. There are advantages to each of these systems.
Depending on the needs of
the photographer, it can be determined which system is most suitable for them.
Bigger is often better, but this is sometimes not the case within the realm of medium format. Though theoretically a larger negative will give a sharper image, this must be compared to additional weight and expense considerations that naturally come with a larger-negative-producing camera system. Essentially, once the type of usage and size of reproductions are determined, it is easier to qualify what system best suits a photographer's needs.
The ETR-Si 6x4.5, for example, handles exactly like a 35mm with all the benefits of a medium format modular system, making this camera in field applications ideal. Of course it also handles fine in the studio, but photographers who are involved in only studio work may find 6x7 a better choice; but this choice also depends upon the size of the final prints that will be produced.
The 6x6 format functions well in many situations.
Photographers who choose the square format generally do so for compositional
and practical reasons concerning on-camera strobe systems and cropping options.
With a square format, the photographer never has to turn the camera to keep the
flash on the top, which is necessary for shadowless lighting. Even though a
square does not fit perfectly with an 8x10 print, using this format allows
vertical or horizontal cropping to be done later to a 6x4.5 proportion. Other
photographers choose to get their images printed square for a different
composition.
