This chart is for one “average” photo and represents a comparison for that picture as a guide. Closed image file sizes vary widely due to their content. The photo in question is an environmental portrait taken with a Canon EOS5D MkIV.
Sometimes I post blogs which describe how I do things and others are intended to be conversation starters and thought promoters. This one falls directly into both camps but it was originally written to start discussions.
How we deliver images to our clients is a subject that photographers can debate until the cows come home or until the technology changes and the debate has to start all over again. For the kind of work that I do most of the time (editorial, PR and corporate) there are a huge number of compromises to be made – most of which are dictated by a small number of factors:
- Does the client have a digital asset management system?
- Will the client want to do anything to the pictures before sending them out?
- Who are the end users and what will they want?
Once you start to gather the answers to these questions you can start to discount a lot of options that, as photographers, we would like to see. Ninety-nine percent of the pictures that I deliver are in JPEG format. It isn’t the best format for quality but it is almost universally recognised and it offers the ability to compress the files. It makes sense to us to save our images at the highest quality available and to deliver the pictures in a way that allows for that quality to be maintained but a surprising number of clients simply don’t want or can’t handle that. A modern DSLR with a 24 megapixel chip produces very large files – even as JPEGs; Too large to safely email. Too large for them to be stored easily unless the client has a decent server or at least a method of storing (and retrieving) a lot of data. (more…)
