Color Theory is a set of principles used to create harmonious color combinations. Colour modes are colour spaces, for example RGB, which is an additive colour model in which red, green, and blue light are added together in various ways to reproduce a broad array of colours. color management is the controlled conversion between the colour representations of various devices, such as image scanners, digital cameras, monitors, TV screens, film printers, computer printers, offset presses, and corresponding media.
Its very important to have technical compatibility in images with specified requirements as some image formats may or may not be compatible with the software you are using, however JPEG and PNG are common formats for images which can be used and are compatible across a range of software and programs. As well as format, the pixel dimensions and resolutions are also very important for images, it can either make your image look clear and perfect, or it can make your image look pixelated and blurry depending on what file size you would like and the quality of said file.
Descriptive metadata is about individual instances of application data, it is the information used to search and locate an object such as keywords or the publisher. Structural metadata on the other hand gives a description of how the components of the object are organised, administrative metadata is a term that refers to the technical information including the file type.
There are numerous different file formats for digital images, with JPEG and PNG being the most common because they work on a wide range of software and support many different colours. However if you are creating something animated, then GIF would be the format to use, though it doesn't support as many colours as what JPEG and PNG support. One example of software would be Adobe Photoshop, the PSD format that is used in Photoshop files, is used by many and is supported to some extent by most competing softwares. A PSD file can also be exported to and from Adobe Illustrator, Adobe Premiere Pro and also After Effects.
Out of personal experiance I would say that Adobe Photoshop is in my experiance the best image editing software. The reason I think this is because, as I previously mentioned the PSD file format that is used on Photoshop is compatable with other software programs, it offers a range of different filter effects that you can use, along side with other tools that allow you to edit your images the way you want them. As well as this Photoshop also allows you to be able to vectorise and rasterise your images, changing the file format of them. Photoshop offers a lot to its users, but another thing I find is very helpful is that it is compatable with all computers or laptops, its not just specific to one brand or type. This is why I think Photoshop is one of the best image editing softwares you can use.
In order to find all the relevent materials you will need there are a number of websites you can do this on, for example the most common one would probably be Google, as you can just type what you are looking for into the search bar, and it comes up with a selection of relivent images etc, another one would be Deviant Art, it works in a similar way, you can search in the searchbar, or you can go to relivant categories to find images, textures, brushes, actions and so much more, it provides you with a lot of materials for your image editing. More often than not all the things you find on Google, or Deviant Art can be imported into Photoshop or other software programs.
If you have an incompatible image the first thing you could do would be to try and export it as a different format. What I mean by this is if for example, you have a PSD file which you try to use on different software and it won't work, you can change this image to a format that will work, such as JPEG, as I have mentioned before JPEG is compatable with a wide range of software.
To produce an appropriate image for a client there are a few things you can do to ensure its success, one example of this would be to do some research, have a look at past work, for example logo's, their website (if they have one), buisness cards etc, and get a feel for what they like. Another thing you can do is to ensure that you have read the breif properly and you know 100% what you are doing, and what the client is expecting from you, and make sure that if you are unsure or you have any questions that you ask said client, to ensure that you produce a piece of work that they and you are happy with, that meets all the standards. You can also perhaps get some feedback off your colleagues, ask them to suggest ways in which you can improve your work, and if they think you are meeting the standards and requirements. Another highly important thing is before you submit your work, make sure you arent breaking any copyright laws.
Ensure that you save your work in the correct formats, for example save it as a PSD file, so that you can edit if at a later date if needs be and a JPEG file if you simply want to view it.
A potential legal issue which could arrise in a situation like this would be copright. Copyright law says that if someone takes another persons work and changes it in any way, you are still taking there work and passing it off as your own, which is a violation of that law and can in some cases lead to you having to go to court, getting fined or even in a worse case, being prosecuted. Another thing to be careful of is to make sure your image does not offend anyone in anyway, as this can also lead to being fined or prosecuted, a way to avoid this could be to ask colleagues if they see the image you have produced offensive, in anyway.
You have to make sure that certain images are kept confidential because of the Data Protection Act. You have to make sure that your work is not disclosed to any other parties, without the consent of the individual it is about. Unless there is legislation, or a legitimate reason to share the information, it is an offence for other parties to obtain this personal data without authorisation. You also have to ensure that you comply with all business organisation systems and procedures relevant to your work.
