How to increasecontrast of image

The field number is the diameter of the image area when seen under the eyepiece. This is often written on the side of the eyepiece, as shown on the right. In this case, the eyepiece has a field number of 20mm. So the image, when seen with the eyepiece only, has a diameter or 20 mm.

To apply the effect you want on an image, drag on the shadow area. Every time you apply the brush, the area becomes bright since the effect is cumulative. Note that each stroke is a separate command, so you can still roll back your brightening effects if you apply the strokes in short sessions. Once the changes are saved, they become permanent.

When you look through the lens of a microscope you see a circular area, the diameter of which is known as the field of view. To work out the field of view we need to know the field number and the magnification of the objective lens.

Whether dealing with high contrast images or low contrast photos, Corel PHOTO-PAINT lets you edit all the image contrast.

Consider the image on the right as seen through the compound microscope with the eyepiece shown above. The microscope field of view when the 10X objective lens is used is found with the following formula:

This brush helps you to brighten shadow areas selectively based on different tones. Once you select this brush, you should also choose a suitable brush type on the selector. Dodge Shadow or Dodge Midtones is the likely option to correct shadows, but always use your best judgment to select the one that works best.

For example, if the field of view under low magnification using a 10X eyepiece and a 10X objective lens is 5mm the field of view when using a 40X objective lens would be 5mm X 10/40, which is 1.25 mm.

Depth of field is the range of depth that a specimen is in focus. A microscope that has a thin depth of field will have to be continuously focused up and down to view a thick specimen, as shown on the right. Different levels of this specimen are brought into focus by continuously adjusting the fine focus.

A soft feathered brush with a size that matches the pixel area will help you avoid instances of hard brushed edges. On the other hand, a large brush enables you to apply the effect in the shadow area in fewer strokes.

Introducing our Optics Silicon Hyper Hemherical Lens! With precise specifications and a Silicon substrate, this lens is perfect for infrared applications.

Use this default brush type to brighten up specific areas in a photo interactively. You can choose from seven brush types of different shapes and sizes. Start by selecting the brighten brush, then set the shape and nib size. When making subtle corrections, use large, feathered bushes. In case it has very strong or too weak effects, tap on the open advance options and use the transparency options to make changes.

Image contrast is the difference in lighting that brings out bright highlights and dark shadows in a photo. High contrast images contain dark shadows and bright highlights, while low contrast photos have a narrow color range.

In case you have shadows in isolated instances, you can use an adjustment filter on the entire photo to correct the shadow. However, this may affect the lighting in the entire picture. You, therefore, need to use the Corel PHOTO-PAINT effect tool since it has a little more finesse that helps correct images better. You can use the tool's two brushes accessible by choosing the effect tool (V) then click the brush selector, either burn or brightness.

If you are taking photos around or near surfaces that can reflect bright light, these areas can make the rest of the image look dull. In this case, you can use the adjustment fillers on Corel PHOTO-PAINT. Make adjustments using the sliders in the intensity, contrast, or brightness dialog. You can do this by choosing 'image' then 'adjust' or simply using the shortcut Ctrl+B. The intensity, contrast, and brightness sliders allow you to make the necessary adjustments as a percentage of the original values. For instance, if your shot was affected by bright water sparkles due to reflections from the sun, there may be an underexposure of the intended object. You can set the three sliders at around 40 percent to improve the overall image and make it more detailed.
