Think first about the purpose of the photograph. For example:
The intended destination will affect how you photograph your work, and you may need to take various shots so that you can fulfil all of the above requirements should they be needed.
The overall aim is to see your artwork clearly, with no reflections and the colours represented accurately. The photograph should be taken from far enough away that the edges of the piece are visible — this is important to get a sense of scale, and the image can always be cropped later if necessary.
If you are photographing a 3D work like a sculpture, you are aiming to capture its dimensions so you can try different and more experimental perspectives and lighting options.
If you plan to edit or retouch your photos, save the original first and work on a duplicate.
When saving an image to a computer, always label it with this information:
Here is an example: Vincent van Gogh, The Starry Night, 1889, Oil on canvas, 73×92 cm
As digital files can be shared all over the world, you can add your copyright claim on a photographed image, i.e. add © 2016 Your Name to an image file before you send it out so each time it gets shared, your image ownership is not lost.
If you are using a smart phone, the images will automatically come with metadata showing the format, size, date and time the image was made, pixel dimension and resolution. Digital cameras vary in what data they record, with some offering different options.
