Filters render artistic effects, distortion, blurriness, sharpness, noise removal, and lighting effects, among others.
Blurriness, color casts, faded hues, botched exposures and light flares are all imperfect aspects of images captured by instant film cameras.
Remember that the images and the entire board might get distorted, so adjusting that also can help you reduce blurriness and that annoying pixelization that sometimes happens on pictures.
Some printers are capable of creating pristine photographic images, while others display pixilation and blurriness when producing detailed images.
