The most important reason that viewers will visit your website is for your art. It is important to present it, therefore, clearly and simply. There are several options for doing this and there are new options appearing as new technology becomes available.
When I first started writing this I was using Photoshop Elements and Dreamweaver 8. I am now using Adobe Creative Suite 5.5 Web. It’s amazing the difference in new technology and will probably always be a novelty to me. It has Photoshop Extended. Photoshop Elements is a perfectly good enough program if you can’t afford Photoshop Extended and will let you do all the things you need to do. Therefore, there is no excuse for poorly presented photos.
Since I am talking about photos let me speak about a newer format. .png 8 and .png24. These two elements are lossy compression elements as is a .jpg or .jpeg. That means that you will loose pixels when you save it but not as much and the color options are in the millions and millions. This makes it a format that is great for the web and presents your art in a clearer way. .jpg or .jpeg is still the preferred format in most applications for exhibits, grants, fellowships and residencies.
So how to present your art. Remember that each artist is different and each website should be professionally presented but at the same time unique and inline with the artists style and technique. I did like the disjointed rollover. That means that you have thumbnails of your work on one side and when the mouse rolls over it, a larger image appears. This allows your viewer to see a larger version without having to click on anything. However with the advent of new technology and the fact that Dreamweaver CS5.5 no longer has the technology to support it, it’s not the ideal way to go.
This artists website has a portfolio system with thumbnails on the top that visitors click and a larger image becomes available below them: http://www.symastudios.com/PORTFOLIO/Pages/PUBLIC_ART.html#8
I’ve also seen pages with thumbnails that open into a new window. This is becoming common again. However, make sure it’s not a “pop up” window (a small window that opens to the top left or top right of the browser). Also make sure there is a way to go from photo to photo without having to leave the separate window. It’s best to have it open to a full web page rather than a “pop up.”
I can’t really offer you more options at this time but keep looking around. Look at what other artists are doing, galleries and museums. See what you like and instruct your designer accordingly. Make sure it’s simple, all about your art and you will have great success.
