Our content editors review each file to check for basic technical and quality requirements. Please review the requirements below before uploading and submitting your files to Marketplace. This will avoid unnecessary rejection notices.
File size and color mode
We require JPEG files with a minimum of 3000px at 300 DPI across the longest edge.
Images must be RGB color mode.
Watermarks, trademarks and copyright
High resolution images must not contain watermarks, signatures, or borders. These elements must be removed, along with any other creative/personalized text before uploading to Marketplace. Clients would be very upset to buy and receive a watermarked image. You can use our 500px watermark which displays your images online but is not embedded in the downloadable file. There is a 500px watermark checkbox in your Photo Manager.
To avoid trademark infringement and to allow your images to be licensed commercially, prominent logos, company and product names must be removed. Not only is this a legal requirement but it also allows your images to be licensed to a wide variety of buyers. Branding includes registration numbers on boats, trains and vehicles.
If you have recognizable artwork in your photo we require a property release signed by the copyright owner. Examples of this are drawings, paintings and photographs that are visible within your image.
Here are some common tricks and issues to reivew on each photo before submitting your photos.
A new French law was recently passed which obligates clients using Commercial images in France to disclose whether the body shape of a model has been retouched to make them look thinner or larger. As of October 1st, 2017 we have updated our Submission Guidelines to require that Contributors submitting Commercial images do not submit to us any images depicting models whose body shapes have been retouched to make them look thinner or larger. Similar to other licensing platforms in the industry, we will not accept images that have been manipulated in this way.
Viewing your image
Always view your image at 100% zoom. At 100%, you can check for sharpness and any technical or quality issues.
The importance of your histogram
Check your highlights and shadows. If they are too dark or too light, consider reprocessing your files. Be mindful of exposure and contrast. You want to avoid any extreme ranges. In the example levels slider above, the photographer has pinched the shadows and highlights by 5. Your camera’s histogram shows you the tonal range from shadows to highlights. A histogram will show if the image is being under or overexposed. The darkest tone is 0 and the brightest is 255. While processing out your file, a general guideline is to not have your shadows go below 5. Only specular highlights or a light source should have a maximum reading of 253. You can make these adjustments in post-processing using curves or levels adjustments.
Dust on the sensor
Sensor dust shows up on your image and should be retouched out before submitting. A client would prefer to buy a file where they don’t have to spend time retouching something as basic, but noticeable, as dust.
To avoid this scenario, be careful when changing your lenses. Always be aware of your environment and avoid wind, dirt and dust.
Mirror dust is visible when you look through your viewfinder, but sensor dust shows up in your image file. Be extremely careful if you clean the sensor yourself - better yet, get a professional to do it for you! If you do find your files have dust, please spend the time on retouching the image.
Creative filters and HDR
HDR or High Dynamic Range must be used with caution. HDR can cause a ghosting effect, noise, extreme colour saturation, and can make the overall image too soft. Be especially careful using HDR when there are people present as skin tones often become too saturated and discoloured.
Below are some extreme examples of technical issues seen with HDR filtering when viewed at 100% zoom (magnification).
Filters can produce fun and interesting effects, but you be careful not to make the image more about the filter than the content. Don’t limit the sales potential of your image by overusing filters.
Here is a great example of HDR done well. Beautiful tones, no loss of detail, and the right amount of sharpening.
Chromatic aberration or colour fringing is a line of colour which occurs between a light and dark area of an image. This fringing will show up when the image is printed. You can prevent this by stopping down your lens (use a high f-stop), avoid using a zoom lens at it’s maximum length and use a high quality lens. You should remove fringing before submitting your file. Additionally, software such as Lightroom now has powerful anti-fringing algorithms that can help remove fringing.
Banding and posterization
Why shoot RAW files? By shooting RAW you are starting with the highest quality your camera allows at the highest bit depth. It gives you a smoother tonal range which helps prevent banding and posterization. Posterization is when there is a lack of tonal range. Be mindful of posterization when processing your files. Watch for excessive saturation and your highlight settings.
Banding is sometimes hard to avoid so be careful with your file adjustments because they might exaggerate the effect. Be careful when adding noise to fix banding.
Digital noise and compression
Excessive noise greatly reduces photo quality and saleability. Limiting noise in your images is another reason to shoot RAW.
Use a low ISO and avoid low light situations. Underexposing your image may introduce more noise in the shadows. Do not add unnecessary noise to cover up problems. It is much easier to reprocess your file so the problem can be corrected.
Sharpening your file will also sharpen noise. Be careful to lookout for this when you are sharpening your images
Watch for noise when shooting in low light situations. Shoot RAW if possible. There is software available that is made specially for reducing noise.
Be careful when blurring or adding selective noise. You want the overall grain of the image to be uniform.
Sharpening is essential with digital photography but one must be careful with the amount applied. Over-sharpening can cause a haloing effect. You want to avoid “crispy” edges, especially noticeable in trees and any other high contrast areas.
Before and after
A 500px Editor flagged this file for technical problems. This may have been caused when the file was processed and over-sharpened. Unnecessary noise was created in the sky and the highlights, as seen in the waves. This image was pushed too far, creating overblown highlights and loss of detail. The photographer responded by doing a fantastic job in correcting the issues.
