![]() ![]() If the image is made on the computer and is not a photograph, painting, or scan, it probably shouldn't be in JPEG format at all - see Preparing images for upload: Do not save diagrams as JPEG. Check format Always save photographs as high quality JPEGs.Images from modern digital cameras which produce very large (6MP or 10MP) files can look much better when slightly reduced in size. If, when viewed at 100% (actual pixels), an image appears slightly blurred and/or there are visible JPEG compression artifacts, it could benefit from downsampling.The current maximum file size you can upload is 100MB. The default minimum size for consideration as a Commons featured picture is 2 megapixels, for example. Check size Although it may only need to appear small in the encyclopedia article, bear in mind that people might need an image in high resolution.Check graininess If there is excessive image noise (possible with some film scans, and very likely with digital shots taken in low light) try using a noise removal program such as Noise Ninja (commercial), Neat Image (commercial) or G'MIC (open source).Check brightness If the image seems dark or the colors are dull, correct the brightness and contrast using a "levels" or "curves" dialogue.If the photo looks too "cold" or too "warm", it can often be easily corrected using a color balance adjustment. Check color Make sure the colours look natural.If the centre of a scene isn't vertical or the horizon isn't horizontal, it might also be an idea to rotate it before cropping. Check composition Cropping an image to remove irrelevant parts of it can make the subject more prominent and improve its visual balance.Purchasing products and services through these links helps support our efforts to bring you the quality information you love and there’s no additional cost to you.Here are some things that should be kept in mind before uploading images: *The Current Photographer website contains links to our affiliate partners. You can try a demo version of Neat Image for free, and purchase a Home or Pro edition from Neat Image’s website. When I have a noisy image, I don’t want to spend hours fiddling with it just to get rid of the grain, and for this reason, the simple (and pretty speedy) workflow that Neat Image provides is great.īest of all, Neat Image also comes as an Aperture or Photoshop plug-in. Neat Image is not hugely refined, but I really couldn’t care less. Once this is complete, images can then be outputted at 8, 16 or 32 bit (depending on which edition of Neat Image you have). Luminance and chrominance reduction, sharpening, and a vast array of other settings can be adjusted, and the results can be previewed using a sample box – click and hold within this box to see the “before”, release for the “after”. The Noise filter settings stage is where Neat Image really comes into its own. You can also load previously used profiles. ![]() Thus, Neat Image is an application that deserves a try thanks to its simplicity and detail. Noise reduction begins with image profiling – the auto setting seems to be very accurate, but fine-tuning is available for control-freaks. Neat Image incorporates a good number of filters that you can apply to the image, also allowing you to increase this number infinitely as well as allowing you to add your own filters. Essentially, the Home edition is designed for images originating from compact cameras. Additionally, the Home edition is restricted to 8 bit image processing, whereas the Pro edition allows up to 32 bit. The Home edition allows for up to 100 images to be batch-processed, whilst the Pro edition allows unlimited batch images. When you input an image into Neat Image, the image exposure may be corrected before moving on to noise reduction. Whether you choose the Home edition ($39.90 for the standalone app, single-user) or the Pro edition ($69.90 standalone, single-user), noise is almost eradicated, with only a small amount of detail being lost. The look of Neat Image – very dull, very functional (almost Windows-like…) – belies a highly polished noise-reducing app. For this reason, many swear by the grain-combating qualities of Noise Ninja, but this isn’t the only app that does a fine job of reducing noise – Neat Image should also be considered as an option. And whilst many image processing apps have noise reduction on them, the results are often very poor. You know the feeling – great light, perfect composition, beautifully exposed but ruined by grain. ![]()
