Which of the following statements describes the benefits about the DNG file format?Each correct
Answer(s): D
Digital Negative (DNG) is a format for storing raw pixel data captured by the digital camera sensor. DNG format stores data before they are converted to any image format. It also contains standard EXIF metadata, date, time, camera used, and camera settings. Data stored in DNG format can be used to convert a file into any other image format. DNG format provides a single raw processing solution that enables a more efficient workflow when handling raw files from multiple camera models and manufacturers.
You want to remove imperfections from a portion of an image so that the texture, lighting, and shading details of the sampled area blend with the source area. Which of the following tools will you choose to repair the image?
The Healing Brush tool enables you to repair imperfections of an image by painting with pixels sampled from the same image or pattern.It matches the texture, lighting, transparency, and shading details of the sampled pixels to the source pixels, so that the repaired pixels merge seamlessly with the rest of the image.Answer-option B is incorrect. The Color Replacement tool is used to replace specific colors in an image. This tool manipulates the color of an image, but the underlying texture, lighting, transparency, and shading details stay unaffected.Answer-option A is incorrect. The Eraser tool enables you to change the pixels in an image while dragging the tool on them. The pixels will change to the background color when you are working on the background layer or on the layer with locked transparency. Otherwise, it will erase the pixels to transparency. This tool is also used to restore the affected area by using the data from a specified history state in the History palette.Answer-option C is incorrect. The Art History Brush tool enables you to paint with stylized strokes.

An image has a white background. Which of the following tools is used to completely eliminate the white background in a single click?
Answer(s): A
The Magic Eraser tool is used to eliminate all similar pixels in an image to transparency with a single click. But in case a user is working on a layer with transparency locked, the pixels will change to the background color.Answer-option D is incorrect. The Magic Wand tool is a selection tool that is used to select a similar color throughout an image. To select a similar color, Photoshop compares each color channel value of the pixel clicked with the Magic Wand tool to all other pixels in the image. A particular pixel will be included in the selection if each component color of the pixel falls within the Tolerance range (range of sensitivity) of the Magic Wand tool. You can specify a tolerance for the tool ranging from 0 to 255.Answer-option C is incorrect. The Background Eraser tool is used to erase pixels in a layer to transparency as you drag through them. This tool enables you to erase the background while maintaining the edges of a foreground object.The crosshair in the center of the brush samples the color and erases all the similar pixels within the circle of the brush to transparency. The tolerance level that you specify on the Options bar of the Background Eraser tool determines which pixels are actually erased, and to what degree. You can also control the sharpness of the boundaries by specifying different sampling options on the Options bar.Note. The Background Eraser tool works even on the layer with locked transparency.Answer-option B is incorrect. The Eraser tool enables you to change the pixels in an image while dragging the tool on them. The pixels will change to the background color when you are working on the background layer or on the layer with locked transparency. Otherwise, it will erase the pixels to transparency. This tool is also used to restore the affected area by using the data from a specified history state in the History palette.

The Transform and Free transform commands can be used to apply flip or rotation on an image.These commands can be used to scale, rotate, skew, and distort an active selection.Answer-option B is incorrect.

The Crop and Straighten Photos command is used to create separate image files from the multiple-image scan. It is an automated feature of Photoshop. It is useful in the situation when a user places several photos on the scanner and scans them in one pass, which creates a single image file. Now, the user can create multiple images from that single image using this command. The Crop and Straighten Photos command works best on the images with clearly delineated outlines.
