There are many excellent reasons for shows and artists to embrace the digital jury process. For shows, advantages include the potential to automate the application process, greatly simplify the handling and management of hundreds, or even thousands of submitted images, and tremendously reduce the time and effort required to collate and analyze the scoring data that the jury produces. For artists, the digital jury process can make it easier and faster to apply to shows as well increasing the accuracy with which their work is presented to the jury. Additionally, artists could receive valuable feedback from shows that are using a digitally system to score applicants.
There are several issues that need to be addressed to insure that a digital jury is a positive thing for both the shows and artists. Our recommendations begin with practical considerations and then address the technical issues.
Perhaps the single largest factor that will speed or inhibit the wide use of the digital jury process is adoption of a standard image submission format. If artists are required to produce digital jury images in different formats to apply to each show, the result may be confusion and reduced applications. Shows that do not specify the exact image requirements of their system or plan to resize images, give the artist little or no control over the quality of their images. A standard format will keep time, effort and costs down for artists, improve the quality and accuracy of the artist’s jury images and will reduce the number of incorrectly prepared images that shows will receive. A widely accepted standard may even have the potential to increase the number of applications that shows receive.
A standard submission format will also reduce the fear and uncertainty that less technically adept artists may have toward the new process. If standards vary widely, or are not clearly stated, even technically sophisticated artists may decide not to submit an application, fearing that they would be wasting their jury fee because the process would not fairly represent their artwork to the jury.
No matter what process a show ultimately decides on, artists who are considering applying to a digitally juried show should have access to detailed information that will allow them to properly prepare their digital images so the digital images accurately represent their art work.
File type, image size, color space, and the color temperature and gamma of the display device all play a critical role in the accurate display of digital images. For those who have no experience in color management these factors may initially be confusing, but are actually fairly simple to deal with. What follows is a discussion of how those factors will affect the accuracy and quality of submitted digital images, as well as our recommendations for optimum settings.
Image type and size
Because image files can be quite large, they are usually compressed before transmission over the internet. We recommend that the baseline JPEG (Joint Photographic Experts Group) be the standard file format that shows ask for. JPEG’s are readable by all programs and browsers and are the most efficient way for artists to send images to shows. Even with minimum compression, files submitted as JPEGs will be relatively small and simple to transmit and store.
Image size is critical because changing the size of a JPEG has the potential to significantly degrade it. If an artist knows the actual resolution that their images will be displayed at they then can optimize their images for that size and be confident that the jury will see those images with the quality intended. Most new digital projectors use the XGA standard (1024x768 pixels) as their native resolution, and 1024 pixels wide by 768 pixels high is also the most common desktop monitor resolution. Unlike slide projectors that can project both horizontal and vertical images, most digital output devices are restricted to displaying a horizontal format. Taking all these factors into account we are recommending shows standardize on one of two image sizes. Both would allow artists to submit horizontal, vertical or square images, selecting the aspect ratio that would show their work accurately, knowing the jurors would have no problem viewing their images fairly in comparison to other submissions.
Please note that when describing the dimensions of an image that will be displayed electronically the only size element that actually is meaningful is the number of actual pixels. DPI (dots per inch) and PPI (pixels per inch) are terms that are only meaningful for images that are outputprinted on paper.
Color Space: A color space describes the actual gamut, or range of colors that can be displayed. Our recommendation is that shows require that images submitted be prepared in the sRGB color space. sRGB (standardized Red Green Blue) is the default color space for viewing images on a monitor and in a browser. It is also the default color space for most digital cameras and projection devices. If an image is prepared in a larger or smaller color space than the display space, the result can be a washed out or darker than intended image.
Color Temperature: Also called white balance, color temperature refers to the color of gray at different levels from black to white. The default color temperature for sRGB is 6500 Kelvin. Many monitors are set to between 7000 toand 12000 degree color temperatures when shipped, as higher color temperatures cause the monitors to appear brighter when seen on a showroom floor. Correction to the 6500 degree standard can be easily made to most monitors and projectors using on screen adjustments. We recommend that shows adjust their monitors and digital projectors to 6500 degrees Kelvin before a jury process begins.
Gamma: Gamma Iis the relationship between the voltage input and the brightness of a monitor. Monitors compensate for gamma to show the desired gray values. A Gamma of 2.2 is the standard settings for monitors in the PC world. Macintosh computers default to a gamma of 1.8. Images prepared using a monitor with a different gamma than the one used by the juror will either look washed out or too dark. We recommend that shows use equipment set to the Windows standard gamma of 2.2, and that they instruct artists applying to their show that they need to prepare their images using a monitor gamma toof 2.2
It is our hope that standards will emerge that will make the digital jury process a simple, reliable way for artists to accurately show their work for judging by show juries.
Whatever image specifications you decide on, artists applying to your show will need to know the details so they can properly prepare their images. The more the artists (or those they hire to prepare their images) know of your system, the more accurately their work will be presented to your jury.
And though we may not have stressed it enough, whatever image size you ask for should be able to display both horizontal and vertical jury images equally, not requiring scrolling to see the image in it’sits entirety if viewed in a browser. Just because the most common display devices use 1024x768 resolution, asking for that 1024x768 size will display horizontal images approximately 33% larger than vertical images.
