A raw file is essentially the data that the camera’s chip recorded along with some additional information. It holds exactly what the imaging chip record-ed. Nothing more. Nothing less.
This means that the photographer is able to extract the maximum possible image quality, whether now or in the future.
A raw file is comparable to the latent image contained in an exposed but undeveloped piece of film.
Before a raw file can be viewed as an image or photograph, the raw file must be downloaded into a raw conversion program.
If you request raw files or digital negatives from your professional photographer you will not able to print photographs from the files unless you have a raw converter and the know how to print a digital image. A raw file is not a print ready file.
A jpeg file (most non professional cameras shoot jpeg) has had the camera’s various automated changes made to the image and then has had some level of potentially destructive compression applied.
Most professional photographers shoot in Raw.

HRDIs are high quality and prepared to ICC (International Colour Consortium) standards. (See Colour Management 5 below)
The skill and time to get the images to this level of quality is extensive. The quality of imagery produced is not what comes out of the camera.
The final print result will depend on the skills of the professional photographer, the Photoshop operator, monitor, software, printer, printer ink and print media. For accurate colour reproduction ALL of these steps need to be calibrated and profiled.
Once the HRDI is removed from the professional photographic studio, the studio takes no responsibility for the final appearance of reproduced image.
HRDI files are suitable for printing up to A3, depending on the software, printing device and print media used.

LRDIs are medium quality images that have been density and colour corrected to ICC (International Colour Consortium) standards. (See Colour Management 5 below)
Professional photographers may make available LRDI’s generally for the purpose of viewing and ordering by email.
LRDIs will not reproduce to professional quality.

Purchasing the digital images includes the following licensing provisions:

A ‘usage license’ is provided with the digital files, this is not copyright.
The client is provided with a license to print, duplicate, distribute and share the images for domestic purposes only.
No commercial usage is provided, i.e. advertising, commercial media, magazine, newspaper, commercial website, brochure or any publication.
The final print/reproduction/result of the image will depend on the operator, monitor, software, printer, printer ink, and print media. For accurate colour reproduction, ALL of these steps need to be calibrated and profiled. (See notes on Colour Management 5)
Consequently, no responsibility or liability is taken for the final appearance or result of reproducing the image files.

Colour management is the process of ensuring colours are true and consis-tent, from capture, to edit to final print.
Every device displays colours differently. Even monitors of the exact same brand, model and age will have slight differences. This is unlikely to impact on the average office user but will have a huge impact on the work of a photographer or creative professional that needs to be able to trust what is displayed on the monitor.
In colour management the colour displaying characteristics of each device are mapped to an ICC profile, the colour fingerprint of the device. When the operating system of the computer reads this ICC profile it knows exactly how the device produces colours and can compensate for colour cast and other variances so the displayed colours are exactly as they should be, – 100% correct and true to the information stored in the image file.
If work is passed on in the middle of the process (e.g. off site printing), co-lour management is even more important since others have no way of knowing how it looked on your screen, unless it is colour calibrated.
Colour Management is the only way to avoid costly mistakes and time-consuming reprints.

Images supplied on the DVD are prepared and saved in jpeg-12 with Adobe RGB 1998 profile attached.
Monitors must be correctly calibrated to view the digital image files accurately.
Printers and the print media used must be correctly profiled to accurately reproduce the colour of the digital file.
