Dennis, Thanks for writing with your question about galleries specializing in HIE prints. While infrared film in general lends itself to unique effects, remember that the major difference between infrared film like HIE and any other film is the film's sensitivity to different portions of the electromagnetic spectrum. I am unaware of any galleries that specialize in any particular film type, including infrared. Gallery owners and managers are usually more concerned with the quality of the image and how well images fit the needs of their clientele than with the specific medium of the image, whether it be oil, watercolor, or, in your case, prints made from infrared film. Therefore, my advice is, rather than look for galleries that would specialize in infrared images, you should look for galleries for which your style and subject matter would be a good match, regardless of the medium. Construct a sample portfolio of your images to tell a coherent story and to illustrate your creative abilities, regardless of the specific medium of the images. Periodically, at locations around the country, the American Society of Media Photographers (ASMP) holds portfolio reviews. That, or something similar, would be a good way to have your portfolio evaluated with suggestions for improvement prior to making gallery visits. I hope that I have answered your questions and concerns. If you have any follow-up questions, please don't hesitate to ask.

In the context of digital photography, a "plug-in" is a small software program which is used by another software program, such as Adobe Photoshop, to perform some task. For example, Photoshop can handle and process a multitude of image formats, such as JPEG, TIFF, PSD, etc. However, many digital cameras, while able to handle some of these general formats, also use a "raw" format. The raw format is a proprietary format that represents a (mostly) unprocessed image. In order for Photoshop and other image processing programs to be able to handle these raw images, the camera manufacturers make plug-ins available. These plug-ins provide the interface between Photoshop and the image. In general, the raw image plug-ins are available at no charge. Adobe Photoshop users can periodically download and install new updates to the "Adobe Camera Raw" module, which is a collection of plug-ins for various cameras. Additionally, camera manufacturers may make their raw plug-ins available on their website for users to download. Other types of plug-ins are also available. For example, many Photoshop filters, such as sharpening filters, are implemented as plug-ins. This type of plug-in is generally not free, but is sold as a product.
