Now that fall is with us, but leaves & foliage are still on your bonsai, this would be a great time to make a visual record of your bonsai’s appearance, and to compare it to a like picture without leaves (deciduous only). This comparison will allow you to anticipate which branches to remove or bend when wiring or trimming your tree in the spring. There also are other reasons to photograph your bonsai: detailing growth history, preparing for publication, confirming insurance value/presence, or merely sharing pictures with friends. Although choice of camera appears to be a major factor, even simple cameras will suffice for most tasks. Digital cameras now are dominant for most photography, and with their many automatic features, instant feedback and computer editing, their use in plant photography has now become widespread. We’ll concentrate on the conditions necessary to make good pictures.
The most important factor in producing good photos is composition – what you see in the frame. Composition is the position of the tree within the frame while considering the aspects of background, lighting, degree of magnification, and artistic content. Generally speaking, the object should not be in the very center of the frame. Some people use the rule-of-thirds concept to position the tree, which lessens the mechanical aspect of the photo and provides a balanced view. Any “blank” space within the frame should remain small. Shoot the picture from the front of the tree and level with the trunk. Be careful about shadows, since they will detract from tree.
Background also is a critical compositional factor – any other object detracts from the main subject. There should be no background clutter. Background color should be neutral and should complement the colors of the plant. Most people use a neutral, beige background, and avoid white, which appears too stark. Of course, if you’re documenting plant growth or features with background stadia lines, these precautions should be disregarded. Indoor photography allows one to use a piece of paper or a blank wall to control the background, but this option is not always available given the size of the tree or its location (e.g. at a garden show). Some internet sites use black backgrounds and lighted trees to get a dramatic effect, but in general, a neutral background is best and is easiest to manage technically.
For advanced photographers, you can override the automatic digital controls and use the camera’s depth of field feature to blur background objects, or if desired, to bring more of the tree (front-to back) in focus. Depth of field controls how much is in focus in front of and behind the subject. Use of a long lens, i.e. magnification, will flatten the image, give less distortion, and allow the tree to be positioned further from the lens – a good thing.
Regardless of whether you are shooting indoors or outdoors, one should always avoid high contrast lighting in close-up shots. Too much light can produce unwanted shadows or washed out, overexposed areas. This high contrast phenomenon sometimes can be avoided indoors by using angled lights or flash units. Most people with multiple or very large trees will likely take outdoor pictures. Ambient light conditions can be either detrimental or advantageous. As with the high contrast example above, sunny conditions can produce unwanted shadows and/or loss of detail. Shooting under cloud cover will diffuse the light and give more acceptable results. Choosing shooting time will also alter your results. When the sun is low in the sky, picture colors will appear more natural and warmer in color to the eye. Overly back-lighted pictures will give darker objects and loss of detail, but the halo effect – if not overdone – also can be very dramatic. Use of filters and diffusers will modulate the light and can soften the picture.
Although not mentioned specifically above, image sharpness also is critical for good pictures. Keeping the subject in focus is usually a camera function. However, some people will override the automatic features of the camera and will use the macro feature to get the best close up pictures. Focusing then becomes more critical. The best advice for macro photography and indeed for taking any pictures of bonsai is to use a tripod. The stability obtained with a tripod should result in excellent pictures, even at less than optimistic lighting.
Lastly, increasing the resolution or pixels in a digital photo will give sharper pictures and detail – especially if you are printing or viewing large pictures. Any digital photo suitable for 8x10 inch prints will give sufficient detail for most uses. You should print out the best pictures of your bonsai and put them in a photo book for easier comparison with earlier pictures or defoliated/branch-only shots.
Regardless of whether you understand all the detailed technical aspects of photography, the experience gained by taking pictures will help you make better pictures. Comparison of your work with published internet photos as examples will improve your results. The important element here is to take pictures.
