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…

B_M_spread

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?

Using the Capture One overlay tool

In the bad old days of analogue when shooting Time Out magazine covers or Music Sales book covers for Pearce Marchbank he had an ingenuous method for enhancing workflow. He would produce a piece of clear film of the cover showing the position of all the type & in pro to the film format of the camera. I  then placed this in the camera viewfinder so that I could position models, props, etc to work around the typography that he had designed. A second, identical piece of film would be used to lay on top of Polaroids prior to making the final shot on film.

Clearly the guys at Capture One have taken this idea on board when they created the ‘overlay’ tool in the Capture One software for the Phase One. Here is a simple step by step on how to use it….

Import your shots into Capture One & select one frame.

Choose the ‘Composition’ option from the left side of the frame.

Move down to the ‘Overlay’ tab then across to button that carries the symbol ‘…’ to the right of ‘File’. Here you select a file for overlaying and navigate to it in the usual way.

The overlay comes in at 100%. Using the 4 sliders beneath the overlay tab you can adjust; opacity, scale, horizontal and vertical position.

Major adjustments to position can be made with the ‘hand’ tool, afterwards minor re-positioning takes place with the tools beneath the overlay tab (as described above).

This shows crop needed for a 48 sheet billboard poster with type ranged left

By returning to the overlay tab & clicking the down arrow at the right hand end of that bar the ‘Clear Overlay’ option is revealed which allows  the opportunity to remove the existing overlay prior to importing a different one.

In addition it’s possible to position the overlay as desired then crop down using the crop tool thus darkening the unwanted image area and confirm that the shot wrk to a different pro, in this case a 96 sheet billboard.

Crop needed for a 96 sheet billboard poster with type ranged left

Overall this tool is absolutely invaluable, saves great amounts of time and makes you look good in front of clients and in my view is another great plus to the Phase One/Capture One.

A debt of gratitude to PM for introducing me to this technique many years ago.

Mixed Lighting – Hoxton

Indi Petrucci’s recent black and white street fashion shoot in and around Hoxton Square shows the versatility of the Elinchrom Ranger Quadra portable flash equipment and it’s suitability for mixed lighting technique. In her own words, “Easy to use, efficient and simple. The perfect kit for a photographer on the go on London’s streets.”

Details: Canon  EOS 5D MkII, EF 24-105mm at 28mm, 1/125 sec, f5, 500ISO

When practicing mixed lighting to create strong visual images with a single flash head the Ranger is an ideal tool. To achieve these particular shots Indi chose to use a ring flash attachment hand held by her assistant either as the principle light source or as a discreet fill-in bounced off a Lastolite. Having scouted locations in advance as part of the pre-production process the whole shoot was completed in just under 3 hours and the results speak for themselves.

The Flash Centre at their various UK locations are the principle supplier of Elinchrom. I’ve used this brand for more than 20 years suppled by TFC and can’t recommend them enough. I find them sturdy, reliable, built to last and able to copy with the worst of the British weather. The guys to talk to are Alex and Sav in London or Kevin in Birmingham.

If you’re keen to learn about implementing the mixed lighting technique then come and join one of our Mixed Lighting workshops. It’s not as complex as it may at first appear.

DSLR – Out of the Dark

January 28 was the day that we ran the first ever ‘DSLR – Out of the Dark‘ practical workshop for people getting to grips with digital SLR photography.

Based at the British Legion Club in Muswell Hill, London N10 we created a studio environment to allow people to shoot portraits and still life with their own cameras whilst Matt & myself where on hand to guide and support as well as delivering a structured seminar.

This is something that we will be running again in the future so watch the website for announcements.
