Creating Panorama Photographs

by Nancy@goneinc on September 9, 2011

A panoramic photo captures an image that is at least twice as long as high.  Usually a photograph with an aspect ratio* of 2:1 or higher would be considered a panorama. For example, 10×20 or 8×16 inch prints would be considered panoramic, with a view that is twice as wide as high.  An image that is as great as or greater than the viewing field of the human eye would be panoramic. A higher aspect ratio, of 4:1 or even 10:1 would be panoramic.

There are cameras which will create a panoramic image with a single shot. There are multiple lens and software to help create panoramic photographs as well as 360° photographic images. But for most of us, our usual still digital cameras using a standard lens along with some stitching software will be more than adequate for pano creation.

There are a number of software stitching programs on the market. One of the most popular is PTgui. (www.ptgui.com ).  Adobe Photoshop and Photoshop Elements have Photomerge feature and does an excellent job for most panoramic stitching.  More recent versions (CS4 or better) do a much better job than earlier versions.

No matter what you use to create the final image, it is the photographic process that will determine how good your final image is.  It is possible to hand hold the camera and still create a panorama but it is much easier to use a tripod. You can purchase specific heads for your tripod to create panoramas, from the inexpensive LensPen Pananic head for about $20 to a Manfrotto Spherical Panoramic Head Kit at $650.

If you chose to forgo the expense of a special head for your tripod there are a few rules to keep in mind. If you are shooting without a tripod, try to use your body as the center point. Plant your feet firmly and turn from your waist. As with any shot, take a breath and hold it before depressing the shutter button.  If you are shooting with a tripod, it is best to level the head if you can before shooting.  The most important rule, however, is to overlap your shots by at least 1/3 of the scene you are shooting. I usually pick out a land mark in the shot about 1/3 from the edge and make that opposite edge on the next shot.

It is also important to keep the settings the same in the camera. If you have auto focus turned on be careful with the focus. It could shift based on the image and it would destroy your panorama.  You may want to shoot in Manuel Mode in order to avoid that from happening. A shift in meter reading could also make the creation difficult, although the software will do some blending of edges.

Try re-positioning yourself and trying the shot from a slightly different angle.  Take several multiple shots from different perspectives. Your first perspective might not work as expected when you start to turn the camera.  The number of shots you use to create your panorama is dependent on the scene you are shooting. I find that for a 180° shot that I will need 5-7 shots.

Creating a panorama photo is fun and rewarding. Going beyond the limits of the lens and camera opens up a whole new way of seeing through your lens. Capturing a wide view makes the scene more memorable and closer to what the “mind sees”.  Try turning the camera for a vertical shot. This will make your panorama wider and capture more of the scene. Good luck and keep shooting!

*Aspect ratio is a measure comparing width to height. Most digital cameras will produce a 3:2 aspect ratio.  The resulting print size of 4×6 or 8×12 is an example of 3:2 aspect ratio.

Color Mode: RGB vs CMYK

by Nancy@goneinc on June 17, 2011

As a giclée printer, I often see confusion about color mode.   For this discussion I will focus on RGB and CMYK, although there are other color modes with different functions and uses.

RGB (red, green and blue) refers to the additive or “light” color process.  When these three colors of light are combined; white light results. The absence of these colors of light appears as black. This is the idea behind display devices, like your TV or Computer Monitor.

CMYK (cyan, magenta, and yellow) are subtractive colors. These colors reflect light back. Theoretically when combined the three colors should produce black. Because the resulting color is not a “pure” black, printers add black (K) to the combination resulting in CMYK.

RGB refers to light (additive) while CMYK refers to pigment, inks or paint (subtractive). Because all printers, be it inkjet, laser, or offset use the subtractive process to produce color it seems reasonable that when creating files for printing one would work in the CMYK mode. This is true for traditional color printing often called offset or 4-color process. The technology behind this printing process is to create 4 separate printing plates. Each plate was originally created by photographing the image to be printed four times using a filter for each color.  The resulting separations representing red, green and blue were then reversed to create the negatives for its color opposite.  For example red is opposite cyan on the color wheel, because cyan is the result of mixing blue and green light and the absence of red light.

Although the inkjet printers and devices that are used today by many professional printers use pigmented inks that are CMYK or variations of CMYK, the file mode format should be RGB.  This is because the files are converted by the print driver or RIP (raster image processor, fancy name for print drivers), into CMYK.  If the files are not in the RGB mode, this process still happens but sometimes with unwanted results because CMYK has a smaller color gamut.

So should you produce files in RGB mode or CMYK mode? The answer is it depends. If your files will be sent to a printer who uses an offset or 4-color process press then you should convert your files to CMYK.  If your printer uses a digital process and prints on an inkjet printer, you should keep your files in RGB mode. If you are unsure what process your printer uses, ask.  If you want the best possible color for your image, be aware of how it will be produced.

The quality and clarity of the image is secondary to how the image was processed. I was recently denied admission to a juried show because the requirement that no digital photo should [...]
