Introduction

Used instruments: white balance setting.

Objects of research: a white sheet of paper.

Task: to adjust the white balance by hand.

NOTE. Tutorial does not contain the information on all the possibilities of the application. Here the optimal way of solving the task set is offered.

Step 1. Launch of the application

Launch the Altami Studio (or Altami VideoKit). For launching the application use the Altami Studio sortcut at the workbench or the menu item Start→Programs→Altami Ltd→Altami Studio 3.0.

Step 4. Reset of camera settings

Reset camera settings. Set the parameter values as it is shown below:

RGB: 128

Brightness: 1

Saturation: 127

Gamma: 20

Shutter: max (parameter responsible for lightness)

Gain: 1

Frames Exposure: 0 (parameter responsible for lightness)

Bits: High (parameter responsible for lightness)

Step 5. Work with histogram — adjustment of lightness

By lightness setting of the microscope move the histogram into the center as it is shown in the picture 3.(a и b, c и d).
