Image "perspective" adjusted using Paint.Net
Camera images are created from the view point or perspective of a cameras lense. They produce a two dimensional view which can be quite different to the three dimensional scene or object seen by human eyes.
While photographers can intentionally position their camera for a more interesting or dynamic perspective of a scene, a hasty snap may produce a disappointing image. Fortunately there are a number of popular free Image Editors that can make changes to an images perspective.

Best smartphone Cameras 2021
At TechRadar we put smartphone cameras through rigorous testing in different lighting conditions and scenarios, and snap people, pets, plants and more to work out how each camera fares in the real world.
The iPhone 11, iPhone 11 Pro and iPhone 11 Pro Max are Apple's newest smartphones, and the tech giant has finally caught up with the competition, introducing a dedicated night mode and an ultra-wide camera on all three.
Meanwhile, Google has introduced a second rear camera on its Pixels, so the Pixel 4s have a zoom lens to grab extra detail close up. Where’s the ultra-wide? It’s missing, but on the plus side, a new Astrophotography mode that can capture night skies, stars, and even entire planets helps differentiate the Pixels from the camera phone crowd.
Beyond the specs and capabilities of the cameras, there are a number of aspects you’ll also want to consider. For example, getting a high storage option or one that supports a microSD card will be helpful if you capture lots of 4K video, while good battery life is important to ensure you don’t find yourself out of juice before the day is done.
There's a lot to consider then, so to help you, we've compiled this list of the best camera phones, each of which we've tested extensively. Find the results of this camera phone test at: TechAdvisor
Image Composite Editor - Free from Microsoft
Microsoft Image Composite Editor (ICE) is an advanced panoramic image stitcher. Given a set of overlapping photographs of a scene shot from a single camera location, the application creates a high-resolution panorama that seamlessly combines the original images. The stitched panorama can be shared with friends and viewed in 3D by uploading it to the Photosynth web site. Or the panorama can be saved in a wide variety of image formats, from common formats like JPEG and TIFF to the multiresolution tiled format used by Silverlight's Deep Zoom and by the HD View and HD View SL panorama viewers.

Imaging Resource's New Comparometer
This tool now lets you compare reference images from digital cameras side-by-side. These images are JPEGs straight from the camera, and were taken under carefully-controlled conditions, to provide valid comparisons of camera capabilities in actual shooting situations. By clicking on and zooming into each image, you are able to closely compare a variety of indoor and outdoor images or the test patterns provided.
You can also download the images (using your browser's "save image as" function) and output them on your own printer, to see how the cameras involved will perform in your application. (See the copyright notice first though!). Check out the Comparometer now...
