As briefly mentioned on the About Us page, the all new Nudi Pixel, which was released in 2024, will implement a community-based concept. This means that support from contributors is crucial for the continuity and sustainability of Nudi Pixel. There are several things that contributors can do. Of course, you must be registered and logged in to access the following features:

1

Upload Photo

We strongly encourage people to participate by submiting their nudibranch photos. But as this web site serves as an educational tool as well as reference guide in identifying nudibranch, we certainly hope you understand that we will only publish limited amount of quality pictures. Thus, stringent quality control of the submitted one will be carried out. Of course we, team of Nudi Pixel, would like to thank you very much for your submissions and very much appreciated your works.

Review the Identification

As you may already aware, we, behind Nudi Pixel, are simply nudibranch lovers and not marine biologist, thus we got some unidentified species of nudibranch or sea slugs here. and once in a while, we made a mistake in identifying a species. If you go to any photo page (for instance, this photo of Chromodoris coi) and you think the identification is wrong, click on the link next to the species name to sugggest the correction (link will be visible if you already logged in).

Published Identity

We have lots of nudibranch photos, to strengthen the identification or to simply correct the misidentified, we have a page called Published Identity where contributors can agree or suggest changes to any published photos. Go to Published Identity page.

4

Published Quality

Even though all published photos have been reviewed before it is published. Prior to 2024, all photos were reviewed by Erwin himself but 2024 onwards, it will be reviewed by everyone of us, Nudi Pixel contributors. The system opens the possibililty for everyone to vote on quality by simply choosing thumbs up or thumbs down on every photo. The photo with highest score has the chance to represent the species on any web pages. Go to Published Quality page.

5

Pending Identity

In the past, all newly uploaded photos will simply display the identification/latin name as it suggested by the photographer. Some of them are good with taxonomy but others still need to learn and many leaving the photos unidentified. To improve the quality of photos that will be published, we have new mechanism to allow contributors to suggest on the identification/ latin name. Once it reaches certain threshold, it is flagged as ready for being published. You can always give your hand by going to Pending Identity page.

Pending Quality

Besides identification correctness, we also want that all published photos to have certain degree of quality to be used as identification tools. It is not only pleasing to the eye but the angle and compositions need to be correct. Underwater photography needs a good lighting technique to produce a photo with good sharpness and correct coloration. Anyone welcomed to help voting on the newly uploaded photos by simply choosing thumbs up or thumbs down on every photo. Go to Pending Quality page.
