Model Releases:  We have very few posed model shots. There are plenty of those available from the generic stock agencies. We are primarily nature and wildlife photographers specializing in the natural beauty of coastal areas, islands, beaches, coral reefs and the creatures that inhabit them, We try to also include some shots of interesting street scenes and architecture as well. You will find some photos with people in them, but they are usually of ourselves or our family and friends, and model releases are available for most photos which include people.

Film:  We have made the move to all-digital, and no longer shoot with film. This section details our approach to 35mm film photography (this website features film photography exclusively). Over the years, we experimented with a lot of film and used both print (negative) and slide film. In the past, with conventional printing methods, ISO 50 or lower slides (transparencies) used to be considered the only "professional" film to use. Advancements in film manufacturing technology has given us some very sharp, low grain, high color saturation print films. With that and the introduction of digital imaging technology, the slides-only rule no longer applies. Today's scanners are equipped with grain filtering technology, and there are also some great stand-alone software applications available for use in minimizing grain. If a photo is extra-grainy, we use multi-pass scanning to minimize the grain and digital noise. If you plan to create large posters, then images from slide film are going to produce the highest quality prints, but at sizes smaller than 8x10, using images scanned from print film should not be an issue. If you have a need to know what type of film was used for a particular image, please consult our database before ordering, as the film type is included.

We used mostly slide film for close-up shooting and underwater photography, but we have experimented with print film and were amazed at how well it captured the iridescent colors of the corals and fish underwater.  For landscapes, print film captured the vivid colors of the tropics really well and was forgiving of the harsh, high-contrast lighting conditions.  Our favorite films were Fuji Provia F and Astia 100 slide film, and Kodak Royal and Gold 100 print film. Fuji Provia F has small grain and high detail resembling lower ISO films such as Kodachrome 64 and Fuji Velvia 50. Colors stayed true and it handled reds really well, making it excellent for underwater macro photography as well as landscapes.

Digital Enhancements:  Slide/negative scanners such as Nikon's that are sensitive enough to pick up small detail also pick up every little scratch and dust particle. Negatives almost always pick up small scratches in processing. Particles in the water can cause spots on underwater photos. Digital edits include cleaning up of scratches, dust that is picked up in the scanning process, and any distracting spots which might be present. Some minor adjustments to contrast, brightness and color balance are also done as needed; and with negative film, a small amount of filtering is sometimes applied to remove grain. We leave the heavy grain removal and editing up to you, as we do not want to over process our images. We never digitally sharpen any of the images.

We are very concerned about honesty and integrity, and know that people are sometimes skeptical of the digital process because they think the images may have been altered. We limit edits to clean-up, much like the photo re-touching with an airbrush professional labs use to remove blemishes from model's faces. Although it is very rare, we occasionally remove a power line, brown leaf etc. that distracts from the composition, but we never add objects. We never combine images or elements from images to make new ones. We never make edits that significantly alter the content of an image. For the most part, enhancements are limited to those one would make in a standard photo lab.

Photographers:  Although the majority of the photographs on the web site were taken by Pauline Walsh Jacobson, Kent Jacobson gets credit not only for his own photos, but for the many times he has acted as the "spotter" on dives, finding subjects for Pauline to shoot. In addition to the Jacobson's photos, the web site features images by Betty Dismukes (Grand Cayman) and James V. Walsh (World War II Nose Art).
