The capturing of all the necessary images in the field can literally take hours to complete and changing weather conditions can sabotage a shoot, resulting in thousands of images on memory cards but with nothing that is worth assembling. In post-production, all of those photos are carefully and painstakingly assembled into the final gigapixel image. Each photo captures only a very small area of view but in extreme detail. To create such huge images, thousands of photos are taken of the same scene using a telephoto lens. They are meticulously created and have resolutions that are hundreds of times higher than typical photos, revealing incredible worlds of detail. Many of my images are 1 to 4 gigapixels (1,000 to 4,000 megapixels) in size and are some of the highest-quality artistic photographs ever made. Selecting a region changes the language and/or content on -high-resolution gigapixel images are those that are near or exceed one billion pixels - 1000 times the information contained in a one-megapixel image. You can always resample as necessary after you’ve tried adjusting dimensions and resolution separately. This means working with what you have, not adding new data to the original image. If you are open to different image sizes, first try changing the dimensions and resolution of your photo without resampling it. You may be looking to enhance a lower-resolution photo to print it - a high-resolution TIFF being a better printing format than a low-resolution JPG. When you’re done resampling, applying the Unsharp Mask filter can help enhance image quality. Designed to produce smoother results.īicubic Sharper: Good for reducing the size of an image. Nearest Neighbor: Best for illustrations with hard edges and no anti-aliasing.īilinear: Adds pixels by averaging the color values of surrounding pixels.īicubic: Produces smoother tonal gradations than Nearest Neighbor or Bilinear.īicubic Smoother: Good for enlarging images. Preserve Details: An advanced upsampling algorithm with a Noise Reduction slider. Choosing the correct interpolation method can help avoid unwanted pixelation:Īutomatic: Photoshop chooses the resampling method based on the image type. The interpolation method is how Photoshop chooses the color values of new pixels. Resampling of any kind, especially upsampling, can result in poorer image quality. Removing data is preferable to adding it, since Photoshop will have to guess at how any newly added pixels should look.Ĭhoosing the best interpolation method when upsampling. When you increase the number of pixels in an image without adjusting the dimensions, you are adding more pixels into the same amount of space and increasing the resolution (or amount of detail) held within each inch. Increasing the number of pixels is called upsampling, which adds data to the image. Decreasing the number of pixels is called downsampling, which removes data from your image. The more pixels an image starts with, the higher the resolution. Resolution is measured in pixels-per-inch or PPI. Resampling images in Photoshop means changing their resolutions by adding or subtracting pixels. How resampling and interpolation affect resolution. However, there are some measures you can take in Adobe Photoshop to help you increase resolution while upholding visual quality. You can increase the resolution of a digital image file, but you will lose image quality by doing so. The only way to resize a smaller photo into a larger, high-resolution image without highlighting poor image quality is to take a new photograph or re-scan your image at a higher resolution. Does this work? Not the way Hollywood does it. It’s a familiar scene: a detective asks someone to “enhance” a blurry image on a computer until it becomes clear enough to make out a key piece of evidence. Can you enhance the quality of a low-resolution image?
