Unit 35- Undertake Technical Adjustments of Images

Editing images in photoshop is very easy, even for people who have never used the programme before. To change the colours of images photo shop uses a thing called RGB colour. This refers to red, blue and green which are primary colours. These three colours are able to make over 16 million different colours. The reason we used RGB on photoshop to edit images is that they are used to be viewed on the computer screen. These colours all have a colour value of 255. When you change the value of each colour the colour you are trying to get will change.

When editing an image it is better to have a big image (high resolution) so that the image does not pixilate when editing it or rescaling it. It is also a good idea to rescale the image when you are ready to the size you want it before adding it into another programme. This will save you time and the image won't need rescaling on the other programme.

There are a lot of different editing software which is relative for editing images but the best of them all has to be Adobe Photoshop. It has so many different features, tools and uses as it allows you to change the image mode from RGB colour or to Grayscale etc. There are a lot of different methods to editing images depending on your design style that you are aiming for. By this i mean there are a lot of tools used for different things. These tools can help you achieve the image edited how you want it to be edited.

To get the images into the software all you have to do is go to file >open> then select the file. If in Photoshop it is better to have the photoshop file as it would have the layers already set out for you. One of the worst things you can do as a designer is not save the original image with all the layers on because if you need to come back to change anything you won't be able to. In programs like photoshop there are options for grids and rulers to help you when scaling images or editing. These are basically guild lines on where/ where not to edit.

Photoshop is a great tool since you can save the original photoshop file image then edit from that and make more images from that. For example a client might want a poster made on photoshop. Once i had finished it i would then save it as a photo shop file. I would then reopen this and edit the colours of the poster then save it again as a Jpeg. I could do this three or four times, this would then give me more examples to show the client and see which one they prefer. If they didn't like it then i could open the photoshop file and edit the original. It is very important that you save your files the correct format as it can effect the quality of the image. This can also matter if you don't want a background on an image and you don't save it as a PNG. 

By law a photographer will own all copyright on any photos that they have taken. This only applies if they were taking for themselves. For example if some one was to take images for a company then those images would belong to the company not the person who took those images. Another way that it wouldn't apply is that if the photographer signed an agreement that assigns the copyright to some one else.

It is quite important to mark your work as it will make it clear that the copyright exists on you images and then they would know who to contact to obtain permission to use these images. This could potentially make you a little bit of money if people wanted to use your work. For example most photographers will charge people for using there images.
