DPP-Part 3; Exercise 3

Exercise; Managing colour

I have to find two images, one with significant colour cast and the other to contain a surface that is grey, firstly to examine the image and see what colour cast it is and then, edit the image to eliminate the colour cast. like the previous exercise, I have to use the two approaches, depending whether or not I shot in Raw.

The first image is the grey image, I shot in Jpeg and Raw, the second image is only in Jpeg format.

1st; Grey/slight colour cast

Original image

I think this image has a slightly cool blue hue to it, it’s not overly apparent, mainly because I shot it on program as time was of the essence in getting the shot I wanted, but the tinge is there. I have this image in Jpeg and Raw.



This is the edited jpeg image;

With this image, I did as the manual said and used the grey dropper on the levels adjustments. It works quite well, I suppose mainly due to the amount of grey area in the photo, I feel I did not have to play around with the RGB selective colours in the levels.



This is the edited Raw image;

As with the previous exercise, the raw image has turned out better, in my opinion anyway!, the image overall, is lighter in comparison and the grey mid-tones seem t be more exact. I changed the WB to cloudy, as it was a cloudy day and that seems to have taken away the slight tint of blueness in the image.

 

 

2^nd; Colour cast
Original image

This has an overly blue tone to it, which is deliberate as I used a tungsten white balance setting when shooting, this is the image that does not have the Raw file.

 

This is the edited image;

I had a bit of trouble with the grey dropper on this one, as I found out, if you don’t use it exactly on the grey area, it goes a bit funny and the photograph becomes extreme colours, I put the grey dropper on the on the little roof at the very bottom of the image, on the front of the cathedral and the spire, that seemed to do the trick. I tried experimenting with the RGB channels, however, the blue in the sky went a bit doolaly!. So I decided to leave it like this, the difference is kind of minimal, but it is a vast improvement in colour tone and the blue hue has almost disappeared.
