RAW vs JPEG

What are three advantages of a RAW file:

·      When you shoot in RAW you record all of the data from the sensor.

·     With RAW you have additional information in the file, so it’s much easier to correct the image without a drastic reduction in quality.

·      Because of the finer gradation of tones and colours you’ll get better prints from RAW files.

What is one disadvantage of a RAW file: 

·      Raw files are significantly bigger than jpegs — sometimes 2 to 3 times bigger.

What are three advantages of a JPEG file:

JPEG images are fully processed in camera and all settings such as White Balance, Color Saturation, Tone Curve, Sharpening and Color Space are already applied to the image.

·      Most modern devices and software packages support JPEG images, making the format extremely compatible.

·      Smaller size also means faster and more efficient backups.

What is one disadvantage of a JPEG file:

·      JPEG images also contain less dynamic range than RAW images, which means that recovering overexposed/underexposed images and shadow areas will be extremely difficult and sometimes impossible.

Under the first heading "Capturing the Images," how much of the data does a RAW file retain after it is captured by the camera?

All the data

Under the second heading "Processing the Files," what are some of the things that a RAW file enables a photographer to edit after the image is taken?

You will have have control over things like white balance, contrast, highlights, shadows, colours and saturation.

Under the third heading "Practicalities," what are some of the factors that photographers must consider when deciding to shoot in RAW?

·      Not every digital camera has the option to shoot in RAW format

·      RAW files are significantly larger than JPEG files, so the space on your memory card won’t have the capacity for as many shots.

·      You can convert RAW images to JPEG, but you can’t convert the other way.

Under the fourth heading "Which one is for you?" why would an aspiring professional photographer need to know how to work with RAW files?

Because shooting with RAW allows you to get the best quality end result from your photo, and brings your game up that extra level.

1. Which file formats discussed have you used in the past?

I have used JPEG/TIFF/GIF/PNG/BMP.

2. What is the difference between a Raster and a Vector file?

The difference between vector and raster graphics is that raster graphics are composed of pixels, while vector graphics are composed of paths.

JPEG
