Solve your problems with digital images. Picture Researchers and Editors like the instant accessibility of them, but dislike grappling with the myriad difficulties. This online course, led by an expert in the field, is an expert masterclass examining bad or damaged images which will equip you to assess inferior quality digital images and to know which ones can be salvaged, and which ones rejected.

Who will benefit from this exclusive webinar: picture researchers, art buyers, photobuyers, designers and picture editors who deal with digital images, of all experience levels.

Course Objectives - what skills will you gain:

  • Accurate knowledge of whether an image is technically acceptable or not

  • Ability to check high-res images before they go to the designer

  • Knowledge to solve problems before they become mission-critical

  • Add value to your career by having skills most image researchers do not

  • Greater confidence in talking to photo libraries and photographers because you can define precisely the problems with the image.

There is no comparable course anywhere addressing these particular problems that picture researchers, designers, art directors and photobuyers face.

The course costs £45.00. To find out when the next webinar is scheduled email


How it works:

The format is an online seminar: Julian will be sharing his screen with you. Your computer will need to have a microphone and speakers, or a headset. You will then be able to hear Julian, ask questions, and see his screen on your computer as he uses his PC, in real time. The webinar will last 60 mins followed by a Q & A session. It is best to be running minimal applications on your computer for optimum delivery.

You will receive the course notes by email before the webinar begins and also have access to a downloadable file which contains the some of the images to work on. It is best if you have Photoshop or Photoshop Elements (or other similar graphics package) installed on your computer but not absolutely necessary. The central facet of the course is the use of the histogram to analyse images. Some free graphics applications, like Picasa, also have the histogram dialogue box so researchers can use these instead of Photoshop.
