When creating high-definition, or HD, images, follow simple guidelines on scene composition, file-type and color correction to guarantee the success of your project. There is a variety of free and premium programs that help you accomplish this task, including Adobe Photoshop, GIMP, Paint.Net or Paintshop Pro.
Choosing the perfect scene composition helps your image retain clarity and sharpness at any size. If your image is going to be seen at different sizes, make sure that detail isn't lost when the image is shrunk to the size of a postcard or blown up to poster-size.
File-format is extremely important, as well. When shooting and producing HD images, always save and edit your files in a lossless file format. This prevents artifacting and image degradation when an image is saved, cropped and reduced. The most common lossless image file formats are BMP, PNG, and TIFF. While lossless files are typically much larger than lossy formats like JPG and GIF, even large HD images are small enough to fit on a flash drive or are easily uploaded to cloud storage.
Accurate color composition is the final required element of producing high-quality HD images. Be aware of where your image is to be used. If it is to be printed or only viewed on a computer screen, it makes a difference which profile you use. The general rule of thumb is that printed images are formatted in CMYK, while Web-viewed images are created, edited, and saved in RGB profile. A printed image created in RGB appears differently on paper than it does on the screen due to the way the printer lays ink down on the paper.
