White Balance Lesson




I thought I'd post the "Before and After" images of the gentleman with the hammer after being "white balance" corrected in Adobe Photoshop Lightroom.

If you didn't look at the final corrected image, would you have known that the original image had a white balance problem? Even with the extremely accurate (well, compared to some other digital cameras) Auto White Balancing of the Fuji S5 Pro camera, UV light still plays a factor on the image. There was also a UV filter on the lens. Still, the image is plagued with incorrect color.

One click of the "eyedropper" corrector in Lightroom yielded the corrected image you see directly below the original. Just point it on something that's grey, white or black and voila! Instant color correction.

This was done on a JPG image as well. This is not a RAW file. For those who do not know, RAW is the type of digital photo file that allows all aspects of an image to be separated into it's component parts. You can make as many adjustments to the image, as many times as you like without damaging the file. And, you can revert back to the original shot if desired too.

You could not do that with a JPG file without degrading the quality of the image. That is until Adobe Photoshop Lightroom was developed! Now with Lightroom, JPG images compete with RAW on this degree of correction!

The JPG images from the Fuji S5 is SO GOOD that there doesn't seem to be a good reason to shoot the Fuji S5 in RAW anymore. Click on each image above and look close at the files. That's straight out of the camera without any adjustments (except for color balance on the bottom image.) All sharpening was done in-camera.

By the way, the Tamron 17-50mm f2.8 lens is phenomenal! It competes favorably with my Nikon 17-55mm f2.8 DX lens which costs over twice the amount!
