| Using a longer (telephoto) lens helps you to keep the picture square. Small variations show up much more with wide-angle lenses than with telephoto. For instance, if you had a 28-100mm zoom lens, it would easier to square it up if you used the 100mm setting. |
PARALLAX and DISTORTION There is another problem called "parallax". Parallax is the problem you have if you are not using a single-lens-reflex camera (SLR). With an SLR, you are actually viewing through the same lens that you are shooting with. If you have a separate viewfinder, then what you see is a little bit displaced from what you actually get. An example of this would be to look at an object with one eye... then close that eye and look at it with your other eye. The difference is parallax. Cheaper lenses, particularly zoom lenses, often have problems reproducing rectangular images properly. You will sometimes see what is referred to as: "pincushion" and "barrel" distortion like this: |

| If you see this problem, you can either get a better quality lens, or try using the zoom lens at different zoom settings. It will often give better results at different zoom levels. Try to avoid the extreme settings such as zoomed all the way in or out. Sometimes you can see the effect in the viewfinder but often it's not easy to see until you get the pictures developed. |
CAMERA STEADINESS Use a tripod to keep your camera steady. 64T is not high-speed film... you will need to support your camera on a tripod and use a slower shutter speed because the film speed is a low ISO 64. The low ISO speed of the film results in sharper images. Higher speed film is available such as Ektachrome 160T, but it is less sharp. It is also a good idea to use a cable release (an inexpensive item) when using long exposure times on a tripod. The cable-release will keep you from shaking your camera when you snap the shutter. This is a cable release: |  |
