We have been working on adjustment layers in photoshop. We primarily focused on curves, hue/saturation and colour balance. Colour theory was very important in todays class e.g understanding the relationship between warms, colds, complementary colours, etc.
Curves is useful for correcting under or over exposed photos, messing with the blacks, whites, darks and lights. Much more range and versatility than using the brightness tool.
This was the first image we looked at, goal is to bring back life to this faded/over exposed image. Using the curve tool. I brought the bottom point to the left edge bottom of the mountain of coverage, then gave a slight curve to the top right. This enabled it to focus on the blacks being darker and the whites being brighter. Creating a much cleaner sharper contrast.
The Cat was originally a very under exposed and dark photo. Using the curves tool brought the points over to the left to make it brighter, making more whites than blacks. I had to be careful not to make it too bright so I can still see the fur textures in the face which has some shadows. Very successful with this one as the whites arent over powering the blacks, showing good balance.
Hue/Saturation is useful for changing the strength of colours and the position of colours in the spectrum. Good for photos taken in different moods, changing foggy to sunny or night to dawn, etc.
Used the hue/saturation to fix the photo of the villas, originally a very low contrast foggy photo. I played arround with the curve tool a bit to up the brightness (decreasing the shadows). I then added more saturation and lightness to eliminate the dull colours. At this point the vilas were looking too bright/warm so i put the hue down which balanced it out with some green. Making the image looks more realistic.
Colour Balance is useful for changing the relationship of complementary colours e.g cyan over powering red or vice versa. Can be applied to shadows, midtones and highlights.
It's all about balance e.g strengthening the warmer colours to battle the colder colours through the colour balance adjustment. If the image is bright, add some darkness. If there's over powering magenta, add some green. If the colours are dull, add some saturation.
Here I used colour balance on the shadows, midtones and highlights. For the mid tones and shadows (ground and mountains) I pushed the red higher (cyan<red) which helps give the image a warmer tone - For the highlights I pushed the yellows, helps making the the blues brighter (river and sky). Overall turned a cold image filled with blues and greys into a warmer image by increasing the warmer colours to balance it out.
I messed around curves and saturation and hues to show more contrast between the different colours of the image. This image has a very warm tone so I used a bit of everything to balance it out. I increased the colder colours through colour balance. Decreasing the yellow to add more blue in the grass, tree leaves and sky which is needed. Added more darker tones in the shadows to show more contrast of the tree trunks, pavement and the person on the right.
This is a fairly complicated image so I really enjoy the trial and error aspect of it, experimenting until the colours work well together and then learning why they work together. Found the last image the most difficult as i couldn't quite get temperature down without making the greens unrealistically blue. But i got a more subtle balance out of it.
Definitely need to practice with these adjustment options in photoshop. Very helpful for understanding colour theory, contrasts, balance between lights and shadows, midtones, highlights and hues.
