This is the first step you have to follow to participate in the IUPAP 100 Photo Contest. Here you choose the nickname with which you will be entering your photo/images (each person can be author or co-author of up to FIVE (5) different images submitted to the contest and, in the case of a series, this should not exceed THREE (3) images per series and a maximum of two (2) series). You must use the same nickname for all the images submitted by the same author or group of authors. Authors must be over 18 years of age at the time of submission. Members of the IUPAP Council, Commissions, Affiliated Commissions or Working Groups are not eligible to participate in the contest. You will have to fill out this part only once to associate the nickname with your personal data. This personal information will remain confidential throughout the selection process.
This is the part of the submission in which you upload the images with which you wish to participate in the IUPAP 100 Photo Contest. You must have already entered the nickname with which you will submit your entries here (AND HERE POINTS TO THE PREVIOUS FORM) before filling out this part and uploading your photo/image. You will have to fill out this part as many times as images/photos that are being submitted by the same author or group of authors (with the same nickname). Upon submission, the authors authorize the IUPAP to exhibit their works, identified by the corresponding nickname, on the IUPAP’s website to carry out the selection process. MAYBE A MENTION TO LICENSES HERE. The full set of rules is available here (again the pdf file).
Here you will have to select one of the two categories of submission ("Beyond our eyes" or "At a glance") and the IUPAP Commission, Affiliated Commission or Working Group more closely related to the theme of the image. Please choose “General Physics” or “Other” if you think that your submission does not relate to any of the IUPAP's commissions or working groups.
