Learning How to Colour Correct

These videos will all inform me on how to colour correct my images, and also included will be a video on how to create effective black and white filters as that is the desired effect that we want for our digipak:

This video has taught me what the blend mode difference means, which is where two images blend by subtracting their RGB values. In the context of colour correcting it is useful to use a grey filled image to blend with the original image through a difference blend, as this shows the part of the image which is closest to grey, shown as the darkest areas after the blend, which can then be colour corrected by adding a curves adjustment layer and then using the middle dropper tool to select this area. This tool acknowledges that the part you have clicked should be grey however has a different colour tint on it, and then it removes this tint by lowering the respective RGB levels or by increasing the opposite colours to balance it out. This will be useful to create a perfectly colour balanced image before applying a black and white tint to our image as it will mean that the black and white image won't be too dark as the unwanted coloured tint in the image created by things such as sunlight or the reflection in the camera will be removed.



This video has taught me how to use Hue/Saturation adjustment layers to manipulate an image into a black and white image, rather than use the black and white adjustment layer, as when the RGB sliders are pulled it affects all of the respective colours in the image. These adjustment layers, along with a grey scale (Hue/Saturation Adjustment layer with the saturation slider pulled all the way to the left), allow for certain elements of the image to be adjusted in terms of how potent the black and white effect is while the rest of the same colours in the image stay the same. To do this you create a Hue/Saturation adjustment layer, click on the hand slider icon, and then click on the area you want to adjust. You then slide the hue to the left and you then can adjust the two colour sliders at the bottom of the adjustment panel until only the area you want is highlighted, return the hue to the centre, and adjust the lightness slider to how dark or light you want the area to be. Any areas which have been leaked from the wanted areas can be masked by Ctrl+I/Cmd+I and then making sure the colour is on white you colour over the wanted area to reveal it from the mask. It also explains how to create vignettes by creating a levels adjustment layer and sliding the bottom slider to the left, creating a solid paint spot, then pressing Ctrl+D/Cmd+d to transform the circle which can then change how the light shows in the image.

These are two effects which will help make the image on our front cover be dramatic, eye-catching, and powerful, all while lacking colour.
