Tips on what to look for at a photo shoot.

The layout and preparations are complete, now it's time for the actual photography. As your product, model or situation is be prepped and the lighting is being fine tuned, this is the time for final adjustments.

How to: Look, view examine, scrutinize, inspect, observe, check and double check.
When the camera is on a tripod and the subject is a still life, this offers the opportunity for accuracy and precision. With the camera mounted on a tripod, view your subject by looking through the camera lens and in front of the camera lens (with one eye). A semi transparent image of the layout can be placed over the photo on the monitor to check lighting and composition. Looking through the lens will offer an accurate view for composition but may show a shallow depth of field (area in focus). 

One View Is Not Enough.
A camera may merely offer a dim or unsharp image to check. A tip for viewing that works well is to place only one eye exactly in front of the lens while viewing the set. While focusing your eye on the subject go through your mental checklist of what to look for: lighting, reflections, hot spots, glare, double shadows, composition, dust, fingerprints, tangents-placement of subject in relation to surroundings, background, foreground... the list can be extensive.

Viewing on a Monitor.
In digital photography the photo can be seen within seconds and can be examined using varying degrees of screen magnification. The range of applications that acquire the exposure from the camera differs from model to model. Generally the photo you see will require some processing, adjustment of the exposure and color balance. Final selection can also be viewed in an image processing program such as Photoshop.

Common mistake at a photo studio.
Big feet. Tripods and light stands are skinny but have a big footprint. Avoid movement near the set, camera and lights. Don't step on any cords and do not touch or place finger prints on the monitor.  Questions are welcome, be inquisitive, but not distracting during the actual photographing process.
