Photographing Images

S_AE:

Choose “S_AE” when you fix the electronic shutter while photographing the subject.

With the electronic shutter fixed to its set value, the DS-L1 automatically sets the camera sensitivity.

•Effective in cases where the brightness of the subject changes frequently while being observed under predetermined conditions and you are concerned with the response of automatic exposure.

•To photograph a moving subject while stopping it with an electronic shutter, use this exposure mode in combination with “1.3Mp” display mode.

•If fluctuations in exposure caused by movement of the subject presents a problem, use

AE_L to temporarily hold the exposure value. During that time, AE_L becomes red.

•Recommended example: Stereoscopic microscope observation

MANU:

Choose “MANU” if you are always photographing under the same exposure conditions or photographing special subjects.

In this mode, the electronic shutter speed or the camera sensitivity is manually set in the Advn. menu.

•The electronic shutter speed can be set from 1/1,000 s to 60 s for DS-5M and 1/1,000 to 600 s for DS-5Mc.

•The camera sensitivity can be set from x1 (C_gn.100) to x46 (C_gn.4600).

•Effective for fluorescent photography where careful consideration is required to determine the exposure, as well as for subjects that have partial highlight reflections.

•Recommended example: Fluorescent photography, stereoscopic microscope observation, metal photomicrography

F_AE:

Choose “F_AE” when the subject is dark, image updates go slow, and you have difficulty adjusting the focus.

Increase the camera gain to prevent the exposure time from increasing.

•In this exposure mode, noise will stand out because the gain is high, but when using (exposure start button), the image is photographed after automatically increasing the exposure time and decreasing the gain.

•Even when “F_AE” mode is selected, if the subject is relatively bright, the original combination of display mode and source will be followed.

•When using (freeze button), the noisy image will be paused.

NOTE: Adjusting the focus of a dark subject can also be performed by pressing the (focus button). When the button is pressed, the camera gain is

increased to adjust the exposure automatically so that the exposure time will not be too long. Then, the live image is displayed while keeping the

exposure status. When pressing (focus button), to increase the response at focusing, "NR OFF" status is set.
