hi, I have a good number of accepted files but the rejected files are all for "rejected for artifacts". you could help me understand where I'm wrong. I put some discarded images below.
Greetings catopleapa1, Oh yes, the mystery of Artifact rejections. I also have had a few so I will give you the first thing one must do. Look at these photos at least 100 % magnification and go over every inch of the photo. You will find lots of them. Flags have a big sky, check there. The woodpile is sort of a heap of artifacts - in the wood itself and in out of focus surroundings. The olive tree shot has a fairly clear center so once you find the clean in focus areas. Perhaps crop out all surrounding things except for the center. Then try resubmitting it as a closeup of olives. The poorly framed Lilly is more background noise and all out of focus. Not worthy of the other similar stock quality. Meanwhile, become familiar with these guidelines about rejection and guidelines for submission. Onward forward to sharper no artifacts work. Regards, JH
Artifacts include noise, gains, color fringing, and other artificial coloration that is many times present in the body of the image. Grains are the dark spots that are usually more visible in the dark and shady areas of the image and is more visible at smooth areas magnified at 100 to 200%. Grains are also visible in smooth areas. As you view these areas you'll notice if there's a light spectrum of colors that should not be there. For example, shadow having colors of purple, blue, pink etc. and not solid black. Color fringes are usually at the edges, most of the times purple. To correct these you need to, with an editing software, apply a small amount of postprocessing. Be careful not to make it obvious.
Knowing your camera is also important. You need to read the manual about your camera so that you can use correctly the different features base on the environmental condition or subject. For example, low light might require a little exposure compensation, or ensure reduced grains/noise you might need to ensure your ISO is set low, and so on. It is best to avoid the use of flash.
Unfortunately, you do have some problems with this. You can see some signs of noise/JPEG artifacts when zoomed in to just over 100%.
This one is more has more focus problems - the stamen is out of focus. It needs to be sharp.
thank you very much for the answers, I will follow your advice
