LightRoom Basics, Editing Workflow, and the best ways to stay on top of post production, featuring PASS.
Subjects Covered: LightRoom Basics, Editing Workflow, and PASS .
Lightroom is a photo editing software that mimics the classic film developing darkroom. It's a tool primarily for Importing RAW images, Developing Images, curating signature looks and publishing large batches at optimal quality.
IMPORT - Lightroom lets you import from your computer or drives, allowing several ways for you to manage the importing process.
LIBRARY - Lightroom takes all of your imports and catalogs them into a library or libraries. This aspect of Lightroom makes it very powerful in the developing process. Like an actual library it borrows strong cataloging functions that make a professional photographers job very easy. Metadata and Tags can be added to your imports, making it easier to find images later on and organizing them for workflow.
DEVELOP - This is where the magic of Lightroom takes place. This part is where the images you import get looks and adjusted. From tonal ranges, to the finest color tuning, Develop is where you will do the majority of your work.
EXPORT/PUBLISH - The very final step of Lightroom, exporting and sending your images out in a batch properly. Lightroom is a strong professional tool, so it's equipped to handle a variety of situations, whether digital or print.
Things We'll Cover (it's a lot of info)
RGB - Computers and other digital devices handle color information as shades of red, green and blue. A byte is comprised of 8 bits. A 24-bit digital camera, for example, will have 8 bits per channel and can use a total of 8 ones and zeroes for the red, green and blue channels. This allows for 256 different variations, or 28, or 256 different values for each color.
Bit - A bit (binary digit) is the smallest unit of digital information. Eight bits equals one byte. Digital images are often described by the number of bits used to represent each pixel, i.e. a 1-bit image is monochrome; an 8-bit image supports 256 colors or grayscales; while 24 or 32-bit supports an even greater range of color.
BitMap -A method of storing digital information by mapping out an image bit by bit. The density of the pixels determines how sharp the image resolution will be. Most image files are bitmapped. Bitmap images are compatible with all types of computers
Megabyte - 1024 bytes MB
Pixel - RGB tiny component in sensor, or screens. More pixels, better resolution
Megapixel - 1million pixels.
DPI/PPI - Dots or pixels Per Inch ("To HELL with the metric system!" - America!)
Under Exposure/ Over Exposure - Things that you shouldn't do, but people do. The loss of information in your highlights and shadows, due to too much or too little light.
Digital Zoom - Digital Cropping - The fastest way to "downres" your work.
Lossless vs. Lossy - the loss of detail/Image data in a file or lossless ability to transfer/compression of files
Moire - Patterns that are created in camera due to sensor confusion. Fixed by stepping closer or further away, or buying a better camera, whichever is easiest at the time.
Noise. - Artifacts in the shadows of high ISO images.
Histogram - A visual representation of the exposure values of a digital image. Histograms are most commonly illustrated in graph form by displaying the light values of the image's shadows, midtones and highlights as vertical peaks and valleys along a horizontal plane. When viewing a histogram, the shadows are represented on the left side of the graph, highlights on the right side, and midtones in the central portion of the graph.
EXIF - Metadata attached to your RAW image from the camera, Lens mm, F. ISO
Fringing / Chromatic Aberrations
GAMMA - The brightness curve of the color spectrum as displayed (or reproduced) on a computer monitor, a printer or scanner.
Gain - Gain refers to the relationship between the input signal and the output signal of any electronic system. Higher levels of gain amplify the signal, resulting in greater levels of brightness and contrast. Lower levels of gain will darken the image, and soften the contrast. Effectively, gain adjustment affects the sensitivity to light of the CCD or CMOS sensor. In a digital camera, this concept is analogous to the ISO or ASA ratings of silver-halide films.
