What's a "Recommendation"? #

A "Recommendation" is the positive evaluation of a picture and an important instrument on Photocentra. By making a recommendation, you are saying that you like the image and are recommending it to other users. Each recommendation has a so-called "weight". The weight of the recommendation depends directly on the author rating. An author with maximum rating therefore has the maximum weight, so his recommendation is most valuable. Conversely, the recommendation of a newly registered author has only minimal weight.

How is the image rating calculated? #

The image rating is calculated from the sum of the weights of all recommendations.

How is the author rating calculated? #

The author rating is calculated using a complicated formula and depends on the number of images you uploaded, the number of recommendations your images received, and the weight of those recommendations. We deliberately do not disclose the exact formula of the author rating calculation in order to avoid rating manipulation

Why has my rating dropped? #

The author rating depends on the arithmetic mean of the image rating. Therefore, the author rating can not only increase, but also decrease slightly if your last images have received less good ratings than the previous ones. The author rating depends on the number of uploaded images. The more images you upload, the higher the rating of the author

Why are my recommendation disappeared? Why my photo has been moved to "Family album" category? #

Photos are moved to "Family album" by the administrator. By moving into "Family album" category photo loses it’s rating and recommendation. A photo can be moved to the Home Album category if it does not meet the requirements of the community (poor quality, uninteresting subject, etc.)

How does a picture become the "picture of the day"? #

Every 15 minutes, two images with the highest rating are selected. The first image is selected from the categories: "People and Portraits", "Wedding Photography" and the subcategories: "Street Photography", "Macro Photography Man", "Reportage People", "Reportage Sports", "Reportage Politics", "Reportage Military" and "Reportage Documentary Photography". The second image is selected from the other categories. In this way, two "pictures of the day" are determined, so that one picture usually depicts a person and the second picture does not depict a person

How big can a picture be? #

The maximum allowed file size is 12 Mb. If the height or width of your image is more than 1400 pixels, it will automatically be reduced to 1400 pixels. If the file size of your image is more than 800 kB (1600 kb for images from panorama categories), it will automatically be reduced to 800 kB (1600 kb for images from panorama categories). This automatic compression of the width, height or file size can degrade the display quality of your image. Images from panorama categories have no width or height limits if the file size of your image is less than 1600 kb

I can't upload the picture #

Please check if the uploaded file is larger than 12 Mb. Save the file again as *.jpg in an image processing program. Please check whether the uploaded file is really a JPG or JPEG file. Try uploading the file in the incognito mode of the browser or with another browser
