The first thing we learned to do on Photoshop was to make sure the colours we are working with on the computer will come out the same after printing it out. The colours can sometimes change because RGB colour, which is used on screen, can create a lot more colours than CYMK colour which is what the printers use. To show this on screen you can use the gamut warning which will show which colours the CYMK printers cannot create.
To counteract this you can change the levels and/or the colour of the original image so that the printers will print out the exact colours on screen and the image will be just as you want it.
After playing around with these for a while you can create an image that will print perfectly using the CYMK printers.
Next we were shown how to use the mask tool to edit images so that parts of the image weren't too bright or not detailed.
First you have to create a mask layer using the button at the bottom right corner of the screen. Then change the levels of the image to get the majority of the image how you want it to be, in this case we just wanted to get the bottom half of the image brighter and more detailed. Then using the mask tool you can take away the top layer to reveal the original image, meaning that the top of this image was slightly darker and not washed out as it was after changing the levels.
Thirdly we were shown how to use the quick selection tool so that you only change part of the image that you want to. This is good for when a part of an image is slightly too dark or light, and using the quick selection tool means that you can change just this one part of the image.
Using the quick selection tool to select the statue in the foreground of this image means that i can just change the levels, colour and brightness of the statue keeping the background sky exactly the same.
Finally we were shown how to create a panoramic image using numerous photos, using a tool on photoshop to stitch the photos together.
Using photomerge means that you can simply select the images you want to put together and then select which layout you want, then Photoshop does all the work for you. Then the only thing you have to do is crop the image and edit it how you like and the panoramic image is done.
