(Editing) 3D Perspective / Shear / Fish-Eye / Special Effects Transformations

Click here to show the 3D Perspective / Shear / Fish-Eye / Special Effects Transformations Screen.

If you want to give the appearance that you are looking at the image rotated in 3D space, you can do so by clicking on the "3D" menu item that is found in the "EDIT" menu. This function also allows you to SHEAR/TILT an image to the left/right. Also, let's say you have taken a photo of a building and when you look at the photo you've taken, you notice that the top of the building is much smaller than the base of the building. This gives the appearance that you were close to the building when you took it. This tool allows you to CORRENT PERSPECTIVE problems. You can also add/correct fish-eye effects. There's also a bunch of cool special effects too like twist and emboss.

If you want to adjust the perspective/shear to a bunch of photos all at once, you can do so with the Batch Feature.

You can take any image and make it shrink as you pan to the right/left/up/down to give it a 3D perspective look. Once you have given a perspective amount, you can slide the smaller side to adjust the angle of view. You can also use the other slider to adjust the amount of image compression/expansion.

3D PERSPECTIVE

You can use the perspective function to add perspective to existing images, OR you can use it to CORRECT perspective problems in existing images. For example: If you have a photo in which the top of the building is very small compared to the bottom of the building, you could fix it by using the Up/Down perspective slider to make the top part of the image LARGER than the bottom part. If you slide it to the right spot, you will notice that your image now has a building that looks the same width from top to bottom. There is a grid you can use to make sure you line things up properly too.

Perspective Direction:
Up/Down
This allows you to control the vertical perspective amounts.

Left/Right
This allows you to control the horizontal perspective amounts.


Perspective Adjustments
Horizontal Slide
This allows you to control the angle of view. Play with it, it's pretty neat.

Vertical Squeeze
This allows you to control the amount of SQUEEZE or EXPANSION in the image.

Reset To Center
This allows you to reset the bottom 2 sliders to the center position. This is the default position.


SHEAR

This allows you to shear an image. It's sort of like tilting or scewing.

Shear Amount Horizontal
This shears in a horizontal direction

Shear Amount Vertical
This shears in a vertical direction

Smooth Diagonals
If you are shearnig photos, then you will want to smooth diagonals (stair-steps). If you have line-art or bar charts, you many want to UN-check this option.


FISH-EYE / PIN-CUSHION

This allows you add Fish-Eye effect or to remove Fish-Eye effect in photos. Fish-Eye effect is where the closer you get to the center the larger objects appear in the photo. Now you no longer need expensive lenses to produce this effect.

Remove Fish-Eye (Pin-Cushion)
This allows you to control if you are ADDING or REMOVING Fish-Eye from the photo. Pin cushion is a popular term used by photographers to indicate an effect that is the opposite of fish-eye.

Auto-Crop
This attempts to produce a final image that has the least amount of wasted space.

Amount Of Fish-Eye or Pin Cushion
Just slide the slider to the right if you want very little effect added to the image. Slide more to the left to add a lot of effect. You can use the slider handles to fine tune and adjust in smaller increments.

Zoom Control
Normally as you adjust the other sliders, the zoom amount is automatically calculated. If you want a different zoom amount, just manually slide this slider.

Vertical Slide
You can roll the image up/down through the center of the fish-eye. It's pretty cool, if you don't want the fish-eye to come from the CENTER of the image.

Horizontal Slide
You can roll the image left/right through the center of the fish-eye. It's pretty cool, if you don't want the fish-eye to come from the CENTER of the image.

Reset To Center
This allows you to reset the right 2 sliders to the center position. This is the default position.



SPECIAL EFFECTS

This allows you create many special effects with your images. Below is a list of all the special effects that you can use.

Twist

Ripple Random

Ripple Tooth

Ripple Triangle

Emboss

Shadow Down Left

Shadow Down Right

Shadow Up Left

Shadow Up Right

Each of the special effects is pretty simple and intuitive to use.

Amount Of Special Effect To Use:
This allows you to control the amount of effect that you are adding to the image.

TWIST OPTIONS:
Twist Left/Right Adjust
This allows you to position the image so the center of the twirl is where you want it.

Twist Up/Down Adjust
This allows you to position the image so the center of the twirl is where you want it.



EMBOSS OPTIONS:
Emboss in Gray Scale:
This allows you to control if the embossed image is pure gray scale or has some color in it.

Emboss Left/Right Adjust
This allows you to control where the light source appears to be coming from for the shadow effect.

Emboss Up/Down Adjust
This allows you to control where the light source appears to be coming from for the shadow effect.



OPTIONS AT BOTTOM:

Show Grid
This allows you to overlay a grid so that you can better align how far to shear or perspective adjust. So, if you wanted to make sure a tree was vertical, then as you play with the sliders, you can see just how vertical the tree is by using the grid. When you have selected the SHOW GRID option, you will see 4 additional buttons that allow you to control the placement of the grid for better alignment.

Allow Enlarging
When you apply the 3D or SHEAR or FISH-EYE adjustments to an image, the image is allowed to grow in size (dimension/resolution) to accomodate the settings. If you want to FORCE the adjusted image to not enlarge at all, then UN-check this checkbox.

Background Color
This allows you to select a color other than BLACK for the background color. This background color is useful when you use Perspective or Shear options which may change the image from a standard rectangular image to an image more like a polygon.

Help
This displays the help you are currently reading.

Apply
This applies the settings to your image and exits.
