Why do the photos taken by my Canon 600d look the same as those of ordinary cameras when uploaded to Renren.com, but look much clearer than mine when viewed by others?

1. The thumbnails taken with a small aperture of a SLR are indeed not much different from those of ordinary digital cameras. The advantage of a SLR is in large pictures, while those posted online are often small pictures.

2. You must adjust the size through PS software according to the restrictions on image capacity, pixels, and size on the Internet. Otherwise, the software embedded in the web page will automatically adjust, and the image quality will be greatly lost, and even appear. Moiré pattern.

3. When shooting online, since you no longer have the advantage of large pictures, try to take advantage of the other advantages of a SLR, such as the colorful spots of blurred background created by a large aperture, etc.
