It can scramble the memory card either temporarily or permanently. The one exception is when we are combining elements from various photos of different bit depth into a single digital image. Plus, Tony Bridge has some words of advice for a young photographer. While we are all for precision and excellence in photography, be sure that the time you are devoting to that extra bit of quality is something that is perceptible and will affect the overall visual value of your image.

Remember: any edits before conversion create the pixels that define a photo; postedits can destroy photo pixels. See Figures 4-5 and 4-6. Both chips work by converting photons to electrons and then measuring or reading the number of electrons, or the electrical charge. Important Accessories There are lots of items in our camera bag and studio that we think of as essential and indispensable, but as much as we would never want to do without them, they are not really vital for taking photographs.
For information on how to use histograms and exposure compensation, see Chapter 5. So, burn any versions that will make it easier to repeat, adjust, or reverse any of the edits you have done. And if you want a range of lenses — zoom, fisheye, ultra-wide, high-speed normal, portrait, macro, medium telephoto, extreme-telephoto, digital-specific, perspective change, and so on — the cost can run into many thousands.

His black and white images are the combination of a Leica M9, a 35mm Summicron lens of 1962 vintage, great patience and impressive powers of observation. Tip Anytime you convert from less to more, whether it is increasing the number of colors, the resolution, or the image size of your photo, you are forcing the technology to invent data.

Tip If you are shooting a subject and the frame includes something with a highly reflective surface, such as a shiny metal or water, it may significantly throw your exposure off. As you see, we tend to have lots of different versions of our photos, even before we get to the versions needed for sharing and outputting. B The color and exposure controls include a gamma curve that can work on individual color channels, as well as a hue, saturation, and lightness interface that can be set to focus on specific hues. When you go from more to less, you are simply reducing the amount of data that already exists. See Chapter 3 on filters. You will need to make your own decisions about how much storage space and file management any individual picture or group of photos are worth.
In other words, choosing your file format while editing should be as free-flowing and ever-changing as your editing needs to be — dependent on the task at hand and its purpose. There are also variations in the design and quality control, and the superiority or inferiority of materials.

This allows the images to be viewed directly, either by holding the film up to any light source or displaying it through a projector.

Rather than adding another expensive, heavy and bulky telephoto lens or telephoto zoom to the amount of equipment you haul around, consider buying a lens extender. Wiley also publishes its books in a variety of electronic formats. These two scales are indicative of one of the essential differences between film and digital cameras.

An ultraviolet filter cuts some of the blue out of sunny outdoor scenes but otherwise leaves the image unaffected. However, because the image sensor is an analog not digital device, it can also produce in between shades of grey. For those of us to whom such values are second nature, trying to decipher the meaning of the much smaller focal lengths of digital lenses designed for smaller image sensors is almost counterintuitive. See Figures 5-1 and 5-2. In a photo that has more transitions and small details, fewer pixels are likely candidates, which means that less data will be compressed. And that has caused some confusion in nomenclature.
