Note: Z-Oset specifies the focus position in the selected channel relative to the focus position in
other channels. Setting the correct Z-Oset is especially important when the fluorescent markers in
dierent channels are in dierent focal planes.
Optional: Adjust display settings
1.
If not already visible, hover the pointer over the Viewing area to reveal the buttons for Display
Settings and Analysis Tools.
2.
Click (Image Display Settings)
to expand the controls for image display settings for the
selected channel.
3.
Adjust (Brightness) , (Contrast), and (Gamma) using the corresponding sliders.
4.
Click (Reset) to return the display settings to their default values.
5.
Click (Image Display Settings)
again to collapse the controls.
Note:
The
Gamma slider allows non-linear contrast adjustments; moving it to the left suppresses
low intensities whereas moving it to the right boosts low intensities. For images with nonspecific
background fluorescence (often called "autofluorescence") moving the Gamma slider to the left may
help reduce undesired background fluorescence. For images with very faint fluorescence signals,
moving the Gamma slider to the right may help increase faint signals and bring them out of the
background, making them easier to see or detect at the lower limits of brightness.
Find a region of interest
1.
Use the
X-axis and Y-axis positioning knobs (“Front view” on page13) to move the sample stage
and bring the region of interest into the field of view.

maximum of 1000%. Right-clicking on a zoomed image r
esets the zoom to 100%.
