Unit 4 Exam Review

Which file type can produce hundreds of trillions of colors?

• TIFF

• JPEG

• RAW

Answer explanation

RAW files capture a wide range of colors, including 65,000 shades of red, green, and blue, allowing for the potential of hundreds of trillions of colors in an image. This makes RAW the correct choice for high-quality image data.

Which file format creates smaller files by removing some information?

• GIF

• TIFF

• JPEG

Answer explanation

JPEG is a lossy compression format that reduces file size by removing some image data, making it ideal for photographs. In contrast, GIF and TIFF do not significantly reduce file size by eliminating information.

Which image format is best for photos with a small file size?

• PNG

• GIF

• BMP

• JPEG

Answer explanation

JPEG is the best format for photographs as it provides high-quality images with smaller file sizes due to its lossy compression. In contrast, PNG and BMP are larger, and GIF is limited to 256 colors, making JPEG the optimal choice.

Which file type is the smallest?

• JPEG

• TIFF

• GIF

• RAW

Answer explanation

JPEG files are generally the smallest among the options due to their lossy compression, which reduces file size significantly while maintaining acceptable image quality. In contrast, TIFF, GIF, and RAW files tend to be larger.

Which file type is most useful for displaying text and detailed, multicolored images?

• PNG

• TIFF

• JPG

• GIF

Answer explanation

PNG is ideal for graphics images as it supports lossless compression, making it perfect for detailed, multicolored images and text. Unlike JPG, it retains quality without artifacts, making it the best choice for clarity.

In what file format should Taylor save a photo for a detailed printed poster?

• jpg

• RAW

• GIF

Answer explanation

Taylor should shoot and save the file in RAW format because it retains the most detail and allows for greater editing flexibility, which is essential for creating a high-quality printed poster.

Which file type allows editing of separate image layers?

• JPG

• PNG

• RAW

• PSD

Answer explanation

The PSD (Photoshop Document) file type allows for editing separate layers of an image, making it ideal for complex image editing. In contrast, JPG and PNG formats flatten images, while RAW files are primarily for unprocessed data.

Which file type captures the most detail during a shoot?

• PNG

• JPEG

• RAW

• GIF

Answer explanation

RAW files capture the most detail during a shoot because they store unprocessed data directly from the camera sensor, allowing for greater flexibility in post-processing compared to PNG, JPEG, or GIF formats.

Which file format retains all original image data after saving?

• RAW

• PSD

• TIFF

• JPEG

Answer explanation

The RAW file format is a lossless format that retains all the original image data captured by the camera, making it ideal for editing without quality loss. Unlike JPEG, which compresses and loses data, RAW preserves every detail.

Why choose RAW files for editing? Select 2 correct answers.

• Colors can be changed dramatically without offsetting image quality.

• Their white balance has already been set by the camera’s automatic settings, allowing for greater control over color saturation.

• The amount of data in the image enables adjustment of the white balance without ruining the image.

• The images are automatically sharper than in any other file format.

Answer explanation

Photographers prefer RAW files because they allow for dramatic color changes without losing quality and provide ample data for adjusting white balance without degrading the image.
