Previews vs Smart Previews
Every image you see in Lightroom is considered a ‘preview’. From the Thumbnails to the Grid view, they are all previews. Smart Previews, however, are user designed presets that aid in convince. They also help reduce diskspace, which increases over all speed.
White Balance
White Balance takes into account the color temperature of a light source in a photograph. The temperature refers to the warm and cool light. Cameras have a built in White Balance setting to help adjust the overall temperature. You can manually adjust white balance settings in photoshop and lightroom as well. White balance settings are usually depicted as fluorescent, flash, daylight, shady, cloudy, etc.
Clone mode vs. Heal modes for Spot Removal
The Spot Removal tool clone mode selects an exact copy of a source to repair a blemish or unwanted objects in a photograph. It is good for items that have texture.
The Spot Removal tool heal mode option has adobe atomically fill the area by finding the most likely source. It usually displaces or blurs the item. Is best to use for smooth objects such as skin and sky.
Brush spot vs. Circle spot for Spot Removal
The brush spot tool is used by dragging over blemished like a brush and taking from a selected sample. The circle tool acts as a one-click repair that lightroom automatically adjusts. Lightroom does this by matching like tones and colors.
Process Versions
Adobe Lightroom has built-in Camera Raw technology which is used to read and repair photos. Process Versions provide a means to adjust sharpening and noised reductions, which equals control in adjusting exposure, shadows, and highlights. Also, Camera Raw provides tools to adjust color tones and create masks. These process versions help the user manually edit photos.
Crop
Cropping can help eliminate unwanted edge detail. Trimming unwanted areas from the photo can reframe the photo, change the point of interest (subject matter), as well as clean up photograph. The crop tool in Lightroom can also be used to straighten photographs. Straightening can help change the point of view or preceptive of the photograph. It can also change the overall feel over a photograph.

What is color imbalance or color cast
Different light sources can cause an imbalance in the overall color of a photograph, this imbalance is known as color cast. It is usually presented as a tint. Fluorescent lighting causes a cold- blue cast and tungsten lighting causes a warm-orange cast.
Graduated filters
The graduated filter creates a gradient mask over your image. The gradient mask can create effects by changing the tone of the picture making parts seem darker than others or creates a ‘fade’ throughout the photograph.
Tone curves
Tone curves allows you to adjust different parts of the tonal range of a photograph selectively. It maps the distribution of tonal values shown on the x-axis and shows the new distribution of values on the y-axis. The darker range is located in the lower left, and the lighter range is located in the upper right. The tone curve ultimately allows adjustment of tonal range of contrast with the manipulation of the line in the tone curve graph.
Hue, Saturation, and Luminance
When you are describing color by its name you are referring to its hue. Most common hues are red, orange, yellow, green, blue, violet. It is represented as a color wheel. Saturation is the boldness or intensity of the hue and the amount of true color (from grey/dull to vivid/unmuted). It is represented on the color wheel as grey towards the middle, to vivid towards the outside edges. Luminance is the measure of brightness of a color, ranging from the minimum values of black to white. Black is underexposed and white is overexposed. Tint, tone, and shade can all be referenced to hue, saturation, and luminance. Tint is pure hue mixed with white, shade is pure hue mixed with black, and tone is pure hue mixed with neutral grey.
How does Lightroom covert a photograph to black and white
Lightroom converts photographs to black and white by mapping each color values to a default tone of gray. You can create different gray scales by adjusting levels of amount of color distribution or selecting a tonal range within the image using the eyedropper tool.
