How should I prepare my images?

How should I prepare my images?

Saturday, October 8, 2022

Use web-optimized JPG files for your 2D artworks.
The less data a single artwork has, and all together have in a room, the faster the loading will be for your visitors.
Scale your files to a size of 900 to 1500 pixels on the longer side – in spite of our limits of 5 MB per SINGLE artwork, try to stay well below.

Resolution: 72 dpi always.
In case you are using high resolution images or print files at 300 dpi, you will only cause longer loading times but no better presentation in the gallery.

ADVANCED

s-RGB colour gamut
Even if your images look fine on your own screen setting, make sure that they will also be shown the same way on all external devices that your visitors might enter with. S-RGB is the most widely used and stable color scheme.

Please crop them decently!
The angles should be straight and the photograph taken in frontal view of the artwork → or straighten this with image editors such as photoshop, pixlr or gimp.
Depict the artwork as large as possible in the photograph; mind the portrait/landscape setting of your camera. Avoid background scenery: you want to have the 'pure' artwork and not the rest of the room it was photographed in.

Mind an even illumination when photographing your artwork. Reflections on shinier areas should be avoided, as the light in the virtual galleries is very even.

If a frame is part of the photograph and not added later to your artwork virtually (see tutorial here), plan for tinted sides of this work (4th part of same tutorial), and that the frame is depicted fully to avoid an artificial 'whiteness' of the canvas edges in the virtual gallery room.

Many Mac Computers and iPhones use Safari as their default browser. Please mind the image export settings mentioned here, best test this beforehand for your specific files.

Also, test the multipage catalogue image display. This full catalogue is only available for you as a curator for download, however once saved, you can send it to your guests as well. We recommend these Export Settings for images in the multipage catalogue PDF as well. If you encounter a display issue of images there, please switch your browser first, and check your image files.

Working with non-rectangular shapes or round canvasses, or Wall Text Panels:

You will need a png file, exported with its transparent properties. A nice online tool is remove.bg, depending on the quality and resolution of the source image.
If you are working with textile art or flat, irregular artworks on a wall, consider a slight drop shadow in the png to create the impression of an off-set piece.

Files with transparent background are also used for our Billboard tool. You can also turn a poster into a billboard text panel or a sculpture-like impression easily!

- mind the photo settings and angles for working with more than 1 png in billboards as shown here.

Remove.bg is a great and very convenient tool. However, with text) it tends to work less precise. Better paste your letters on a transparent blank background in this case. We recommend a text resolution for wall text panels above 30 pt as the letters are hard to read in smaller type, especially from a distance across the room. Sans Serife typefaces are easier to read on walls.
In case you are using white type on a dark wall color in your exhibition: the preview image won't show the white text on (default) white background, but it will show up nicely on the wall. You can also make use of the scaling factor for such transparent text panels to get the size on the wall just right for the room.
