Space Requirements |
| With
the exception of our Table Top Studio Kits for small product imaging, the
least uninterrupted floor space you will need is approximately 12'x15'
(4X5m). You may be able to setup in a smaller amount of space but moving
the camera and lighting for optimal results may become difficult. We
recommend 20'x20' (7x7m) when possible. Select an area that is mostly
painted white, gray or a neutral color. A room painted red could add a red
tint to your photos. This tint could be removed from the image, but it is
better to start with a neutral color image.
A hard floor is recommended
over a carpeted floor. It is not desirable to roll background paper over
carpet. Light stands and background supports will not be secure on a
carpeted floor. |

Ambient Lighting |
| Be sure to
examine the lighting in the room before constructing your shoot. Excessive
"ambient" lighting can have an undesirable effect on the color accuracy of
your images and could cause tinting. Turn off most room lighting but leave
enough light on to be able to see all of the equipment. If the room is lit
with fluorescent or sodium vapor lights assure that these lights are off.
If the room has substantial daylight entering through windows either mask
the windows or shoot at night.
You will be attempting to light your
subject with pure studio lighting so that the camera can properly adjust
for bulb color temperature. Take some test shots and preview them on a
quality calibrated computer monitor to make sure the ambient (room)
lighting is not casting an unwanted tint. Laptop LCD monitors are not as
good as CRT's in representing colors so we suggest that you connect your
laptop to a tube if possible.
If you can't sufficiently reduce ambient
light, look for another location for your shoot. |

Camera Settings |
Digital cameras
"auto" exposure and focus modes are optimized for "vacation photography",
shooting people outdoors or with a built in flash. Setting your camera for
studio photography with "artificial light" requires intricate knowledge of
your cameras control features. We can not emphasize enough the importance
of studying your camera manual related to the features and settings
discussed below.
- White Balance:
Light has a wide variance in color
temperature which will effect the overall color tint of a digital image.
Digital Cameras provide adjustability to compensate for variation in the
color of light and this function is referred to as "White Balance".
The optimal white balance setting is "captured" by the camera and is
typically available on most 4 mpix and up digital cameras. This feature
allows you to "custom set" the white balance using a "white card" placed
in front of the camera. This feature is available on the FUJI S5200 and
the FUJI S9000 cameras and is frequently referred to as "custom" white
balance. This option will provide near perfect color reproduction when
using artificial lighting. Study your camera manual for procedures
on setting "captured" or "custom" white balance. (NIKON refers to this
feature as pre-set white balance) If your camera does not provide
"captured" or "custom" white balance, you should consider upgrading your
camera.
The second choice is selecting a "preset" white balance. Study your
camera manual for procedures on setting a "preset" white balance.
Use "interior", "incandescent" or "Tungsten" for our continuous HOT
lighting kits. Many cameras today provide several presets for florescent
lighting. If your camera does not provide several florescent presets then
use "daylight" white balance with our ALZO Cool lights.
Using a "pre-set" white balance may not reproduce perfect color but will
always be consistent when using a specific light source. A consistent
color shift is easy to correct in software, and once you get the
correction parameters set, you will use this adjustment on every image
and get excellent results. Using a preset is a better choice than "auto"
because you can consistently correct the color shift.
"Auto" white balance is your last choice and should be avoided.
"Auto" white balance can cause random color shift depending on the
subject, and this color shift will require individually color balancing
each image in software.
Color correction with the
QP COLOR KIT is
the ultimate solution for perfect color reproduction. This software
solution will always guaranty color fidelity no matter what white balance
options are available on your camera.
- Focus:
Use "Auto focus" for most shots and use "manual focus" for close up macro
focus of very small objects. Most digital cameras have very sophisticated
focus controls and are perfect for objects more than 1 foot from the
lens, and in most cases better than your eye. Always use Manual
focus for very small objects when you are in "macro mode".
- Auto Metering:
"Spot" or "Center Weighted" metering is preferred for most objects,
especially when shooting with a
Table Top Studio
or Tent. When
shooting with a white background the "averaging" light meter of a digital
camera will darken the object and produce a gray instead of white
background. Spot metering on the subject will produce far better results.
If your camera only provides "averaging metering" you should consider
upgrading your camera.
- Exposure
Compensation: We have found that
most digital cameras require "Exposure Compensation" when using studio
lighting. Exposure Compensation provides the ability to influence the
auto exposure control of the camera and allow you to correctly expose a
subject on a white background. Typically when using "Spot" or "Center
Weighted" auto exposure control you will set the Exposure Compensation
from +1 and up to +2.
You will need to experiment with your camera until you get satisfactory
results and them leave the camera set to the necessary exposure
compensation setting.
- Manual
Exposure Control: Manual control of exposure provides the
ability to manage the aperture of the lens, which is very important for
maximizing "depth of focus". Small apertures (larger numbers like f-8 of
f-11) are the most desirable settings to maintain sharp focus over an
entire 3 dimensional subject. Setting the camera to manual exposure
control or "aperture priority" will allow for the selection of a small
aperture. When using "aperture priority" the shutter speed will be
selected by the camera and in manual mode by the photographer. In many
cases, with small apertures, the shutter speed will be slow and a tripod
is essential.
- Shutter Release:
When photographing objects, we use a tripod and the camera self timer,
shutter release cable or remote control shutter release to assure a rock
steady camera. Even mounted on a tripod, the motion of pressing the
shutter button on the camera can reduce the image quality. The
FUJI S9100
provides for a shutter release cable which is a highly desirable feature
for studio photography.

Composition |
| It is best to
almost fill the camera's viewfinder with the object. Many digital cameras
view finders and LCD displays do not display the full image captured by
the camera. A light touch on the zoom adjustment will allow for fine
adjustment of framing the image. For some cameras with limited zoom you
will have to re-position the camera to fully "frame" the subject. In
addition, the aspect ratio of the frame of the camera should be utilized
when shooting tall or wide subjects. A
camera tripod that includes
tilt rotation allows the camera to be rotated 90deg to the side to shoot
"vertical" aspect objects. Using the full frame of the camera will produce
the greatest image detail, particularly after cropping the image.
It is best to keep the camera away from
the subject and zoom in on the subject. This will assure accurate
perspective of the subject. If the camera is too close to the subject
requiring a "wide angle" zoom lens setting, this can distort the shape of
the subject. |
