Creative Opportunities - Hasselblad HTS 1.5 Manual

Creative opportunities

The HTS 1.5 can provide many opportunities to improve a
normal shot. The whole idea of being able to manipulate where
the plane of focus in the subject lies offers scope for creative
opportunities that are difficult to achieve otherwise. Although
digital manipulation can often provide similar effects it should
be remembered that not all effects can be created digitally. In
addition, much time and skill is often required.
A case in point would be the appearance of out-of-focus areas
in a selective focus shot, for example. Here, the bokeh of the
lens also plays a part in the creation of these parts of the
image that will produce unique imagery difficult to replicate
digitally in a realistic manner.
Selective focus
Just as tilt can 'increase' the depth of field (as demonstrated,
only an apparent increase. In reality, a change in angle), it can
also 'decrease' the depth of field by an opposite action. Tilting
the lens 'the wrong way' to define the plane of focus in the
subject in combination with a large aperture setting creates an
effect that displays great emphasis on small, specific areas.
Longer focal length lenses and closer proximity to the subject
increase the effect. The examples here use the same focus and
aperture settings, only the tilt angle, and thereby the angle of
the depth of field plane, has changed.
Tilt and Shift together
There can be many cases where combined problems might
be solved by the combined solution of tilt and shift together.
For example, an architectural detail on a tall building could be
captured to (a) maintain its perspective by using shift and (b)
isolated from distracting details (selective focus) by using tilt.
Creatively, the combined use can produce some unique results.
Note that there are slight restrictions regarding the combina-
tion of shift and tilt. Check on the chart shown here for a rough
guide to combinations that will not display vignetting.
MOVeMenTs
The lens can be shifted 18 mm, either upwards or down-
wards, and it can be tilted 10 degrees up or down. Tilt and
shift can be combined according to the diagram.
hTs settings are presented on camera grip LCd and are
also embedded in the image file.

General
Only the user can judge what is acceptable in image distor-
tion compared to a 'straight' shot. What might normally be
described as technically wrong by one person is considered a
creative addition by another. It is therefore not possible to warn
against mishap when using tilt and shift. It is wise to remember
the occurrences that can take place so that you then either
induce them or at least be aware of them if unrequired.
Integral automation built into the whole system prevents
exposure miscalculations from the initial estimation, so it is es-
sentially only the visual aspects that need to be of concern.

It is advisable to always check for vignetting. Even when extreme movements
are not used, sensor size, filter holders, extension tubes etc can all combine to
create a situation where vignetting might occur. See FAQ for more information.
