Doesn’t a photographer just take the photos from his/her camera and print them? Not even close. A lot of things can be changed and made better. This can be time very time consuming but the results are worth it.
This image the JPEG image taken straight from the camera. The lighting is actually pretty good but seems a bit dark and dull. There are also a lot of shadows. This is the image that the camera takes and does its own adjustments.
A RAW image can also be taken with the camera. This image is taken from the camera and unprocessed. No adjustments are made and the image is uncompressed. Lightroom 5 can import RAW images and make adjustments to white balance, brightness, and contrast. Lightroom 5 can also brighten up shadows and make colors pop out more.
The same image can be imported into Photoshop. The lowest balloon has an important year on it. With Photoshop it was possible to take a balloon from another photo and paste it onto this photo so the year is now visible. The same can be done with heads.
