What Can Be Done Through the "Adjustment" Function?
The Adjustment feature in UltraPic focuses on modifying the geometric properties and orientation of your image. It allows for precise control over size, shape, and perspective, giving users flexibility in both basic edits and creative transformations.
Zoom
When you scale an image, you're essentially changing its overall size. This is done by adjusting its height and width.
Width
This refers to the horizontal dimension of your image, from left to right. Increasing the width makes the image wider.
Height
This refers to the vertical dimension of your image, from top to bottom. Increasing the height makes the image taller.
Lock Ratio(Aspect Ratio)
There is an option in the middle of the height and width titles---Lock ratio. 1. When this option is locked, changing either the height or the width will automatically adjust the other dimension proportionally. This means the image's original shape (its ratio of width to height) is maintained, preventing it from looking stretched or squashed. For example, if you have a square image and you increase its width, the height will also increase by the same percentage, keeping it a perfect square. 2. If the aspect ratio is unlocked, you can change the height and width independently. This can be useful for specific design needs, but it can also distort your image if not used carefully.
Rotate and Flip
You have these options when it comes to reorienting your images:
90-degree rotations
These are preset rotations that will turn your image precisely 90 degrees clockwise or counter-clockwise. You might see options for 90° left or 90° right.
Horizontal Flip
This action mirrors your image along a vertical axis. Imagine holding a picture up to a mirror – that's what a horizontal flip does. Left becomes right, and right becomes left.
Vertical Flip
This action mirrors your image along a horizontal axis. It's like turning the picture upside down, but specifically reflecting it from top to bottom. Top becomes bottom, and bottom becomes top.
Manual rotate
You can also manually adjust the specific rotation angle. This gives you precise control, allowing you to rotate the image by any degree, like 5 degrees, 45 degrees, or 183 degrees, for fine-tuning or creative effects.
Wrap
These tools allow you to deform or shift the image for correction or creative effects:
Vertical Perspective
This adjustment changes the apparent perspective of the image along the vertical axis. Imagine looking up at a tall building; the top appears narrower than the base. Vertical perspective adjustments simulate this effect, making objects appear to recede or converge vertically. It's often used to correct converging lines in architectural photos or to create a sense of depth.
Horizontal Perspective
Similar to vertical perspective, this alters the apparent perspective along the horizontal axis. Think about how a long road appears to narrow in the distance. Horizontal perspective adjustments can make objects appear to recede or converge horizontally, useful for correcting wide-angle lens distortion or creating a dynamic, receding effect.
Vertical Skew
This allows you to slant the image vertically. Instead of keeping the top and bottom edges parallel, vertical skew will tilt the top edge relative to the bottom, or vice-versa. Imagine pushing the top of a rectangular box sideways while keeping the base in place—that's a vertical skew. It's often used for creative effects or to align an image with a non-orthogonal background.
Horizontal Skew
This lets you slant the image horizontally. It tilts the left edge relative to the right, or vice-versa, while keeping the top and bottom parallel. This is like pushing the side of a rectangular box up or down. Horizontal skew is useful for aligning images with tilted surfaces or for generating abstract shapes.
Other Controls
Reset
If you're not happy with the changes you've made to your image and want to start over from scratch, simply click this icon. It will revert all the adjustments in that particular section back to their original state, allowing you to begin your image editing process again with a clean slate.
Undo and Redo
Step backward or forward through your editing history, one action at a time.
Summary
In essence, the "Adjustment" function empowers you to fix common photographic issues that arise from camera angle, lens distortion, or simply wanting to reorient an image in a specific way. It ensures that lines appear straight, objects are properly aligned, and the overall geometry of your photo is pleasing and accurate.
