March 2013 - Digital Group - Impactful Mono

Post by spb » Sat Mar 09, 2013 12:15 pm

Many thanks to Peter Jones for covering for me last month.

NEWS
Nikon have announced the launch of a London Nikon School in April of this year. One day courses already available to book include D7000 Skills for £119 and Speedlight (flash) for £149.

An interesting Rambus and Binary Pixel technology has been developed to reset over-saturated sensor pixels in mid-exposure. This should enable an increase in the dynamic range of cameras - of particular application to compacts and phone cameras which are prone to burnt-out highlights.

Nikon have acknowledged a problem with exceptional amounts of debris appearing on D600 SLR sensors. This will require a service visit to fix.

IMPACTFUL MONO
We have covered colour to mono conversion techniques in this group before (see downloadable paper on the mono group page of the APS website) but I gave myself the challenge of producing a dramatic mono conversion from a particularly low-contrast colour image taken under misty flat lighting conditions. I am no mono expert and was looking for the best quick fix. Here is my 'journey';

After opening the original raw file in Photoshop Elements 10 I tried the Enhance>Convert to B&W options. Given that the original had no strong colours, the various defaults were weak and the colour sliders were of no help. The 'Scenic Landscape' setting was the best of a bad lot. I then tried the dual Hue and Saturation adjustment layers method (see paper) with little improvement. Of course, I could have started upping the contrast with levels and curves to dramatise the result but I was hoping for a path to a quicker fix for future conversions.

Moving on to Lightroom, the B&W presets offered a greater variety of results and the Red High Contrast preset was moving in the right direction. Further tweaking of the settings would no doubt have improved this further but my reservation with this approach is that the original colour image is no longer available after exporting the image into Photoshop. Within Lightroom the Graduated Filter and Adjustment Brushes would be helpful in achieving localised adjustments, eg darkening the sky - it seems that mono landscapes require a stormy sky!

Back in Elements, I fired up Topaz Labs B&W Effects (£40 or less with discounts and bundles) and quickly added drama with presets such as Dynamic II Smooth. The Local Adjustments feature enables up to 5 detailed masks to be created for dodging, burning, smoothing etc which is a powerful feature, although going beyond the presets could potentially involve the manipulation of over 50 sliders which is rather too many, I feel.

Nik Silver Efex Pro 2 (£133) has a reputation for being the premier mono conversion plug-in so I was keen to try it on 15 days free trial. The implementation is quite similar to Topaz and the presets High Structure Harsh and Full Dynamic Harsh were good and Film Noir 1 was even a touch too dramatic! The Control Point feature enables localised control over the image although I was slightly disappointed to find that it was limited to circular brushes - albeit any quantity of circular brushes capable of being linked together and with edge detection.

I had taken three bracketed exposures of the original scene comprising 0, -2 and +2 stops and my next experiment was to combine these with Photomatix HDR software to create a more dramatic colour image. Subsequently opening this into the Topaz and Nik plug-ins gave me yet-more conversion options.

Reviewing all of these options side-by-side I decided that the non-HDR Topaz Dynamic II Smooth conversion was closest to my goal. Opening this into Photoshop I then applied adjustment layers to modify tone and contrast to small areas until I was happy with the result.

So, in conclusion, last year's decision to invest in the Topaz suite of plug-ins proved valid and I was happy with the range of results and control offered by B&W Effects. Interestingly, this has recently been updated to version 2 free of charge and compares very favourably with the Nik software which I have always felt to be very over-priced. Nor are Nik upgrades free - the Silver Efex Pro upgrade to ver.2 was £66! Nik have recently been bought out by Google so it will be interesting to see what effect this has on their pricing model.

EXTREME NIGHT-TIME PHOTOGRAPHY
I recently returned from a trip to Nevada where I experimented with some night photography for the first time in years.

Death Valley is an excellent dark-sky area and our stay at Furnace Creek coincided with an outing by the Las Vegas Astronomical Society. It was a clear night and I was able to capture some great exposures of the Milky Way with tripod, fisheye lens at maximum aperture and exposures of up to one minute. The images through the expensive LVAS telescopes were interesting but less impressive than I expected. Tiny dots merely became slightly bigger dots.

In Las Vegas the night sky is totally obscured by the glare from a million neon lights but zooming in mid-exposure produced some interesting zoom-blurs of the lights. A neutral density filter enabled longer exposures.

Photography inside the casinos is frowned upon but discrete use of my iPhone yielded good results and the Slow Shutter Cam app kept me amused for hours. Uniquely, this enables you to open the shutter and watch an exposure build up in real time. After choosing when to close the shutter, a slider allows one or more of the intermediate blurred (or 'creative') exposures to be saved to the Camera Roll. The sensitivity of the camera can be reduced to enable the app to be used in brighter conditions too.
