My photography workflow

I've been asked recently about my post-shot processing, especially how I get shots to my pics site so soon after an event and I thought it might be of interest to some if I spec'd it out.

My primary aim is to spend no more than 2 minutes per shot - from camera to web. The first smart thing to do of course is capture a good shot first up since no amount of post-processing can fix it - or as a journalist mate of mine says 'you can't polish turds' - eeew. This means capturing the shot as cleanly as possible - good exposure, good focus, nice composition and if possible try and weave some emotion into the shot which can mean waiting until a cyclist's expression is emotive or reflects their riding personality or which best conveys the nature of the race or event.

Having got a keeper worth posting to the web, here's what I use to make it happen:

1. Thumbsplus 7 on top of an SQL Server database for image management
2. Adobe Photoshop CS2 for complex image processing
3. Nikon Capture NX to convert Nikon RAW .NEF files
4. Adobe DNG convertor to convert .NEF to .DNG formats
5. Adobe Bridge

1. Photo management

I've used Thumbsplus since the late 90's. It's currently up to version 7 and shortly coming out as version 8. Out-of-the-box TP uses the Microsoft Jet Engine (the actual database behind Microsoft Access) to manage photo files. I've dispensed with the Access ('Jet') storage and instead linked TP to an SQL Server Express 2005 backend.

The speed, indexing, security, reliability and certainty that SQL Server offers is way above what the Jet engine can do; in fact, being able to locate one image out of 100,000+ in a few milliseconds is critical when responding to online request for certain images.

Thumbsplus also has an image viewer called TPView which doubles as a very capable editor. It's especially useful for crop, rotate, contrast changes etc. If your photography is mostly for news - online or print - then TPView is probably all you need. It can't dodge, burn or repair images but that's not really necessary for the work I do.

Thumbsplus can also be configured to launch applications such as Photoshop using DDE (dynamic data exchange). It will pass selected image(s) to the called application. This reduces processing time considerably and makes TP an exceptional image manager - bit of a sleeper in fact since it doesn't get a lot of coverage compared to many other lesser systems currently in vogue.

2. Photo processing

Photoshop CS2 is my preferred application for complex image processing. If you know Photoshop then you'll understand its popularity. Allied with Bridge and the many plugins available it's a great tool. I'm sure there are many other applications that do some things better than PS CS2, but for all-round image/photo processing it does me.

3. From camera RAW to disk

Nikon Capture NX comes as a licenced application with most high-end Nikon cameras. It's a fine tool for converting .NEF format images to something that Photoshop CS2 and Thumbsplus can work with. Being a Java application it's not the fastest piece of software, but it does a commendable job converting RAW .NEFs and quite a bit of useful RAW processsing - exposure and whitebalance adjustments in particular.

Since Photoshop CS2 has now probably fallen off the upgrade path it's unlikely to ever be able to open the newer Nikon RAW .NEF files so Nikon Capture NX is essential for getting files to a format the PS CS2 can understand. I could of course convert the .NEF files to Adobe DNG (see next section) format and go that way but I reserve that extra step for scenic stuff where speed is not an issue - remember we're looking for '2 minutes tops per photo' so another step is a burden.

I should add that I hardly ever capture cycling events in RAW .NEF - the high-quality and hence large file size is not really necessary unless a particular set of circumstances make for either tricky lighting or white balance settings or where exposure is difficult or when I'm shooting something I know will probably end up in a magazine. Those shots deserve the highest quality for later processing.

4. DNG - a camera RAW to disk alternative

Adobe has pushed hard to establish a non-proprietary standard for storing digital images in a format than any application developer can read and write - a standard that then should exist far into the future. Their DNG convertor takes Nikon .NEF (and many other Camera manufacturer formats) and creates a .DNG (a 'digital negative') formatted file.

The DNG format will open in CS2 so this is an alternative to Capture NX's transformation. There's a bit of chat about which is better - Adobe's DNG convertor, or Capture NX - but I haven't tested each enough to know. If I was producing fine-art images I'd probably care but it's not a big deal for web/print news media.

5. Adobe Bridge for image management

Bridge offers image management and some processing capabilities prior to processing in Photoshop. It 'can' work as an alternative to Thumbsplus, with some extra goodies thrown in, but it is not a patch on the speed of Thumbsplus with a SQL Server backend.

I only use Bridge occasionally since it's faster for me to flick back to Thumbsplus, locate another image(s) and use Thumbsplus' DDE link to send those images to Photoshop or whatever other application link that I've set up.

--

Sports photography is like a cross between gold panning and fishing - you can catch lot's of little'uns (the dust), get the occasional goodie (the nuggets) - but in the end all the keepers get processed - as fast and clean as I can; these tools make it happen.

NSW / CORC Round 1 Downhill - 6th April 2008

Saturday Practice


By my estimation 227 riders turned up for the NSW MTB Round 1 Downhill comp. at Mt Stromlo - that's a lot of subjects to practice fill-flash with.

I like these downhill events for photography practice - the Downhill course mostly faces east so riders are coming out of the afternoon sun which tests the fill-flash thinking; access to the jumps is easy and I can get great angles, and these riders are not what I'd call camera shy - they're happy to 'work it for the camera' so to speak so most shots have plenty of action about them.



For Saturday I stuck to the plan of the 70-200mm f/2.8 on the D3 and the entirely workable Tokina 12-24 DX on the D300. For tight berm shots the 70-200 is simply awesome - I just set the AF auto AF-area and let the D3 figure out the best focus points. But this doesn't work perfectly since the wide sensors are not cross points (I believe) and can suffer in low light, but at 3pm on a sunny day this is hardly an issue.


The great thing is that as riders come around the berm they're about 5 metres away so the focus can be on their handlebars, hands, front wheel or their head but at that range it matters not. That's why the 70-200 cranks - it is just so fast. (I shot the Vets at Lookout Hill last Saturday arvo and I spent some time testing autofocus speed with a single focus point and it continues to amaze - focus feels instantaneous - spooky).



Having the D300 mated to 12-24 is very handy. But it requires thinking and planning. With such a relatively slow auto-focus in this combo you need to think about the comp beforehand and watch carefully as the shot evolves else you lose the rider and end up with an average landscape.



I tried some heavy-handed fill-flash with the D300 and 12-24 but as the experts would attest the flash is going to struggle to fill that space. So I zoomed the flash to 50mm or so and directed it a little to the left where I wanted to comp the shot.




Worked pretty well the sun as the main light from behind and fairly hefty fill-flash - but generally I wasn't particularly excited by it. - back to Strobist and Planet Neil for more practice me thinks.



I'm thinking I'll just go with D-Lighting on the D300 and no flash and see what I get. I read Graham Watson mentioned D-Lighting recently and how it 'has almost made the flash obsolete' - I'm yet to be convinced but a few tests of D-Lighting on the D3 yesterday is very interesting and more experimentation is planned.



I'll follow this up with some chat about the Sunday comp. round on 6th April - I left the 70-200mm at home and went with my 24-85mm. I felt the 70-200 was just a bit too long for such close action. And as I mentioned in previous blog the 24-85 is not particularly the crunchiest nut in the pack, but I was happy with the result. It has inspired me to get the new full frame 24-70mm AF-S VR (don't really need the VR but there it is) to see how it goes. I'll probably mount the 18-200mm DX VR on the D300 and turns things around completely.
