Unit 39

We will finally talk about Digital Asset Management (DAM).This consists of management tasks and decisions. Digital asset management systems include computer software and hardware systems that aid in the process of digital asset management. The media asset management (MAM) sub-category of digital asset management mainly addresses audio, video and other media content. The more recent concept of enterprise content management (ECM) often deals with solutions which address similar features but in a wider range of industries or applications. What this is all about is storing your files online. You can obviously save your files onto the desktop in their own folder but say if you needed a backup of them or needed to access them from a different computer how would you go about it? Storing the files online is a very easy thing to do.

It is of huge importance to save your files in at least three locations being desktop organised into appropriate folders, USB and finally online storage. When archiving data it is seen as important to burn onto a dvd and then store in a cool dry area away from any kind of fire hazard such as heater. However I find that online storage such as dropbox or i-cloud is the safest location to store images and manage your archiving.

I imagine a lot of you have got a hotmail address. If you have noticed when you now send an E-mail you are prompted by something called Windows Skydrive. This is a program that is merged in with hotmail. What it does is basically acts as an extension to your computer storage. You can create folders just like on the desktop and just add your work to them. These can then be accessed when you log onto your E-mail account, no matter where you are. Skydrive allows up to 5GB of free storage. There are many other type on online storage centres. Mediafire is one that at first sounded too good to be true. Unlimited storage for free. It is now one of the most used online store centres. It has over 500,00 users around the globe. I myself use Dropbox. It's not the best as you only get 2.25GB free storage but I'm not one to use loads of space so for me that's more than enough. If you are needing to have more space and need to access your folders and files online you first of all need to make an account. Usually just an E-mail address and a chosen password will be all you need to do.

If you have a hotmail account then you already have 5GB of free space to use all you would need to do is log in with your hotmail address and that's it sorted. With others when you sign up they would usually send you a confirmation E-mail to make sure that you aren't trying to hack anyone or do anything like that. To confirm the E-mail all you need to do is log onto your E-mail address and then find the E-mail from whoever it is you have signed up with and just click confirm. When you confirm you are agreeing with their terms and conditions too. Now onto colour management. In digital imaging systems, colour management is the controlled conversion between the colour representations of various devices, such as image scannersdigital cameras, monitors, TV screens, film printers, computer printers, offset presses, and corresponding media.


The main goal for colour management is to obtain good matches over all colour devices. What this means is that if something has been filmed on a digital camera, it has to show up on a television, PC monitor and as a printed poster as the same colour that it was filmed in. Colour management helps to achieve the same appearance on all of the electronic devices listed above. Most of the colour management technology is already implemented within the operating system (OS).  A cross-platform view of colour management is the use of an ICC-compatible colour management system. ICC stands for The International Colour Consortium. You can approach the colour management system other than just using the ICC. At the consumer levels colour management currently applies to still images rather than videos, so basically colour management is still in its infancy. There are two different types of colour profiles, Embedding and Working spaces. Image formats themselves such as JPEG, PNG, TIFF, PDF, SVG and EPS may already contain embedded colour profiles but they're not required to do this by the image format. The ICC was designed to bring developers and manufactures together. The ICC standards permits the exchange of colour spaces and output device characteristics in the form of meta data. This then allows the embedding of colour profiles into images as well as storing them in a database or a profile directory.


The other type of colour profile is working spaces. Working spaces such as sRGB, Adobe RGB and ProPhoto. These are colour spaces that facilitate good results while editing. An example of this is, pixels with the equal usage of RGB should appear neutral. Using a large or a gamut working space will lead to posterization and using a small working space will lead to clipping. There are obviously different operating systems over the rage of different computers. These all have different ways of providing colour management. The Mac OS has provided colour management since 1993 through a program called colour sync. From 1997 the colour management in windows has be provided by an ICC colour management system. Starting off with windows vista, Microsoft introduced a new architecture called Windows colour system. Operating systems that use the X window system for graphics use the ICC profiles and support for colour management on Linux. In 2005 most web browsers ignored the colour profiles. Safari 2.0 and Firefox 3 were the only exceptions. In Firefox 3.0 it was disabled by default but users can enable it themselves if they need to. They do this by installing an add on and they could enable either ICC v2 or ICC v4 colour management. Since Firefox 3.5 colour management is enabled by default but this is only for tagged images. IE9 (Internet Explorer 9) is the first Microsoft browser to partly support ICC profiles. The only problem is that it doesn't render images correctly according to the windows ICC settings. All it does is converts non sRGB images to the sRGB profile so it doesn't really provide any colour management at all. Finally as of 2011 Goggle Chrome doesn't support colour management by default.
