File Formats: RAW v JPEG

RAW & JPEG are two different types of electronic file

The principal differences between the two types are:

  • RAW files are literally the raw data as produced by the camera at the moment of pressing the shutter
  • They have no ‘built in’ file format
  • You are then free to adjust this data through Photoshop or a similar application on a computer
  • You can change; exposure, white balance, contrast, brightness, etc
  • You can return all settings to the start point and begin again
  • A RAW file is, in effect, a digital negative

 

  • JPEG’s are generated by the camera after exposure & are written onto the memory card
  • Preset data for exposure, white balance, etc will be embedded in the file & can never be removed
  • The parameters are decided by you in advance
  • Your latitude to change & make alterations afterwards are very limited
  • The file will be compressed & this is achieved by discarding information that can never be retrieved

 

If you are working digitally then having a camera that will allow you to shoot in RAW format as well as JPEG can be an advantage.
However a JPEG that is produced by the camera at the same time as a RAW is not as satisfactory as one that you generate yourself from the RAW file during post-production.
Many DSLR’s will do both RAW & JPEG at the same time but this will reduce storage capacity.

 

Why shoot RAW?

  • When creating digital prints of the highest exhibition quality & size
  • Shooting high ISO values in low light
  • When you want to make high quality monochrome conversions
  • Photographing a subject with a high dynamic range
  • When you are uncertain about the colour temperature of the subject

 

Why shoot JPEG?

  • When the end result is for small scale or low quality output
  • If you need fast workflow
  • When you need low res images for web or onscreen use
  • When you need to shoot quickly
  • When the end result requires minimal post-production

Borough Market, Jan 2014 – Take 2

Paul Shelley took part in the Borough Market street photography workshop last month and shot with a Nikon D300. Afterwards he edited his shots then cropped and resized them to fit into the picture boxes on the PDF layout. He and I did a final session remotely so that we could discuss and feedback before making a final PDF with his final selection of shots in place, and here they are….

In Paul’s words, ‘I loved the day at the Borough. Thanks for your coaching and guidance. I have been working on the selection of pictures and have just weeded them so that I have now got the three sets.’

Borough Market – January 2014

The first Shadows and Light workshop for 2014was shooting street photography at Borough Market, London, SE1 on January 18th.
To make this as realistic as possible to a commissioned photo shoot participants are invited to shoot their images to the specific requirements of an editorial brief, on the premise that a magazine has asked you to shoot a photo story about what makes the market vibrant and thriving.

On this occasion I decided to set myself a slightly different assignment, something that has grown out of a couple of recent conversations with Ed Kashi and his coverage of the aftermath of Hurricane Sandy in NYC and commissions from Time Magazine and NBC.

Whilst the clients busied themselves with the task at hand I used whatever spare moments I had to shoot the same brief but just using my iPhone with the 645pro and Snapseed apps. Then I placed the my selected files into the In Design file & saved as pdf’s, as you can see below…

Three spreads and a cover.
As part of the ‘homework’ with this workshop participants go away and edit 3 selections in Lightroom (or similar) then mail the jpegs across so that we can generate pdf’s, thus giving them the opportunity to see their images in the context of the finished magazine spread.

There will be another Borough Market workshop at the end of 2014 so why not come along?
