The requirement may be there because the competition is for unmodified images - this is common with photojournalism competitions where only blanket or minor changes are permitted. Theoretically it would be possible as compressed NEF is based on a TIFF container and a "wide" JPEG/JFIF variant IIRC.Īnd all is not lost as, having run these kinds of competitions, I can say that you may still be able to enter depending on what type of competition it is and why they want raw files. You cannot (should not) produce a raw from a jpeg. It is possible, if this is a local competition, that they've just copied the rule from somewhere else, so it might be worth getting in touch with them. This (if it's an option on your camera) may be an option in the future. I (as an amateur) almost always shoot RAW+JPEG, as many of my shots are just printed with at most a little cropping, but some need proper work. So you're probably out of luck this time. I've seen RAW+TIFF submission requirements explicitly for this reason. Having the RAW file gives them the ability to check how much you've modified the image. Post-processing is part of the digital workflow, and the question is more one of how much is acceptable.
Although no longer as popular or common as it was historically, it is still an important file type. This file type revolutionised publishing allowing certain curved items to be printed that previously could only be printed on specialist CAD printers.
Postscript addressed this by defining a language that allowed applications to instruct the printer how to display objects on the page. Prior to the development of PostScript, it was not possible to print images and text on the same page. ps extension is a file type used by the publishing industry.
PNG was intended to be able to transfer images on the Internet, not professional graphics, and so does not support other colour spaces (such as CMYK). PNG supports palettes of 24-bit RGB colors, RGB images or greyscale or RGB images. GIF as they also include an 8-bit transparency channel, which allows the colors in the image to fade from opaque to transparent GIF images only support fully opaque or fully transparent pixels. GIF file), but without those copyright limitations it cannot be animated like a GIF image. PNG uses indexed colors and lossless compression (like a. It was created originally to replace the GIF file format when it was announced that the companies who created the GIF format wanted royalties. PNG pronounced ping is a format for storing bitmapped (raster) images on computers.
