RBA's Astrophotography

CreativeCommons Required Attribution line

Posted: May 27th, 2010

I often get requests from using my images in cases when permission isn't really needed. Before asking, it might be helpful for you to read the following.

As stated at the bottom of all pages in DeepSkyColors.com, all the images I post here are licensed under a BY-NC-ND Creative Commons License.

The BY part means that if you use any of the images posted here, you must attribute the work in the manner specified by the author. So what are my requirements as far as work attribution? All I ask you when using any of my images, as far as crediting authorship, is to include at least this minimum required credit line:

Rogelio Bernal Andreo (DeepSkyColors.com)

Such credit line should be readable when looking at the photograph. That means you shouldn't include the credit line in such a way that a casual viewer of the image isn't able to read the credit line, for example using a font size that is very difficult to read, or far from where the image was placed (page footer, another page, etc). At the same time, it is suggested that the credit line doesn't distract the viewer from the image

And just to be clear:
  • The NC part means Non-Commercial, in other words,  you may not use any of my images or content for commercial purposes without permission.
  • The ND part means Non-Derivative, that is,  you may not alter, transform, or build upon any image or content posted on DeepSkyColors.com, regardless of whether I have posted such content somewhere else.Resizing is acceptable. If you need to crop the image, please contact me.
As long as these three conditions are met, you are free to use any image or content posted here on DeepSkyColors.com and no specific permission is required from me.

Does that mean you can not use my images for commercial purposes or that you cannot create derivative works, etc? Of course you can! But for any of such uses you must contact me first and obtain permission (usually for a fee).

I am working on a small video project for a missionary friend who will be reporting on the work he is doing in Brazil. I have been looking for a nice starfield for some time and finally discovered your site. One of the photos - darkriverpan - really struck me and I would like to know if you would grant me permission to use a portion of it in the project. Thank you for your help. Nathan Patefield

think that the M-31 GALAXY, AND STAR DE VEGA must more be investigated.
it is of great importance to deepen the inquiries.

Rogelio, my sincere thanks for your generosity in making available your great photos. I have made use of these in our new facebook page: iopna (non-profit)and I hope you are happy with credit being given on an accompanying note rather than squashed into the timeline teaser. We may not see things the same way but then again you may like to draw my attention to phenomena that we could publish.
Best regards.

I hopped onto your website through Astronomy Foundation website.

I am an amateur astronomer from india engaged in spreading the interest of astronomy amongst layman, specifically school children.

I have read your CC post here, and was wondering if I can use your images for my website - which is under development. A proper citation and a link to your webaite will be mentioned on all pages of my website.

I require your permission to do so.

Appreciate your help.
