Paul Gallagher at RPS DIG 1/5/16

May 4, 2016 in Information

Some of us went to talks by Paul Gallagher on processing and printing. Here are some notes I made during the two talks, which I thought might be of interest.

Paul uses Adobe Camera Raw (ADR) and Photoshop (Ps). ACR is functionally the same as Lightroom. He works largely in mono.
Starting in ACR….

  1. Don’t change colour temp or tint until later.
  2. Use Highlights and shadows first.
  3. Set black and white points.
  4. Don’t touch contrast yet, use clarity first.
  5. Early on, particularly before sharpening, correct CA (chromatic aberration) but
  6. Don’t use lens profiles unless really needed.
  7. Sharpen (a little) – keep radius low <1 and use the Masking slider to limit the areas sharpened.
  8. Now export to Ps
  9. Lasso tool to select areas for adjustment and then use Curves tool to adjust. This method would also be used round the edges of the picture rather than applying a standard vignette which Paul thinks is a crude tool, narrowing the viewers vision of the picture. Darken by pulling down the whites in curves.
  10. Use shift/alt/control C to make a copy layer to go back into ACR to make any further adjustments.
  11. Back to Ps for smart sharpen with blurring set to Lens Blur rather than Gaussian.
  12. Any further burning in to be done at 1%
  13. Use 360ppi for printing (Epson) and use Advanced Black & White on Epson printers for best mono.

If anyone else who attended thinks we need to add anything please let me know.

L&CPU Annual Individuals’ Competition 2016

March 10, 2016 in Information

The L&CU competition which we entered in February was the CLUB ANNUAL, but next we have the ANNUAL INDIVIDUALS’ competition where you as members select your own work to enter. It is a chance to see how your work does in front of three PAGB judges compared to work entered by members of all the other (c.100) clubs in the Union.

Work entered might be selected for the L&CPU exhibition, the folios and also to represent the L&CPU in the PAGB Annual Inter-Club Competitions – if this happens you will feel very honoured but your prints will be lost to you for over 12 mths and nearly two years in the case of a PAGB selection. Other prints are returned sometime during the summer break.

It is for PDIs and prints and the categories, rules etc are just the same as for our own competitions. What you enter is entirely up to you, but do remember that you are up against the whole Federation and you may only want to use your very best work. You do NOT have to make a full entry in any particular section – you could enter just one image if you wish. The entries must not have been used in this competition before.

All work is marked out of 15 and there are commendations and medals on offer for the best work.

The judging is on 7/8 May, entries have to be made as PDIs (yes, PDIs of prints too) and they will be required by 10th April, a Dropbox File Request will be set up soon. The final date for handing in the prints themselves is at the competition with Nantwich on 14th April.

Here are the rules for the L&CPU Annual Individuals’ Competition.

Repairing Old Photographs – George Steele LRPS CPAGB BPE 2*

February 12, 2016 in Crewe PS news, Information

Family photographs, lovingly passed around, kept in wallets, displayed in bright light, often end up in a parlous state, faded, cracked, creased and stained. Digital photography of course provides the possibility of recovery and repair, and with patience and skill they can even look better that they did originally.

George has acquired great skill over the years in doing this restoration work and he showed us examples of different kinds of repair. These techniques of scanning, tonal adjustment and cloning can, of course, be applied to any photograph and remarkable things like making cars, telegraph poles and even buildings disappear with a bit of careful cloning can be of great interest commercially, though some would frown at the excessive use of the technique in our competition pictures (it is expressly forbidden in nature photographs).

George showed a remarkable way of cleaning up noise in a digital image using the LAB channels in Photoshop. Much software is available to help clean up noise but this seemed remarkably effective in the example he chose. With the image in Photoshop he displayed the LAB channels (Image>Mode>LAB colour) and then used “Dust and scratches” to both the A and the B channels. I am sure some of us will be trying this technique on our own work very soon, so watch this space!

Crewe PS Take A Bath – 21 Jan 2016 – Peter Robinson & John Royle

January 21, 2016 in Crewe PS news, Information

Crewe-Swimming-Poolweb

Crewe PS are pleased to support the local history societies by helping with their photography and today two of us were recording some details of Crewe Swimming Pool, known to all as the Baths, which is shortly to be supplanted by the Life Style Centre.

There was much civic pride in the Baths when they opened in 1937 and many Crewe people will have fond memories of school swimming lessons, galas, competitions, enjoying a soak in the private baths or even first meeting their future life partner there.

The baths will close in March, but there may be some open sessions to give people a last chance to view it. A poignant time it will be; with the empty pool looking forlorn, but an unmissable one too for many local people.

We may also get the chance for a more general photo session. Today we recorded the laundry with its belt driven washing machine, spinner and mangle. The drying cabinet was fascinating, with massive pull-out racks on rails, the whole contraption resembling the way that paintings are stored in gallery archives.

There is an excellent booklet by Barbara Billup about the early history of the Baths online here.

Tough Mudder Event

September 12, 2015 in Information

TMs_0736web

Here is a shot of our club members after a meeting! Well, OK, maybe not.

Member Bob Brown last year presented us with a real winner entitled “Official Photographer” taken at the Tough Mudders race held at Cholmondeley Castle. The photo above, he tells us, is a team shot taken after the event. The team are stationed in Norway but represent six nationalities and include some top brass too! The course is 11.2 miles, has 29 obstacles, with names like Cage Crawl, Hangin’ Tough, Island Hoppiing, Mud Mile, Arctic Enema. As Bob has shown, a great event to shoot.

The event this year is on the 12/13 September weekend.

Shooting Eventing by Martin McGing

September 4, 2015 in Information

MartinMcGingEventing_web

One of the benefits of being a member of a photographic club is you have the opportunity to see a wide variety of work which can inspire you to venture out and try something new.  Over the past two seasons I have seen some excellent eventing images and earlier this year I decided that I would try my hand at horse event photography.  I soon realised that these events are taking place most weekends and quite a few are literally on our doorstep.  My personal preference is photographing competitors on the cross-country course.  Water jumps are quite popular and you can get some good action shots.  I typically walk the cross country course looking for jumps that have a clean background with the sun over my shoulder.  I try to vary my shots so that some include the location and some are tightly framed.  During one event we were walking the course and we heard that Zara Phillips had started the cross country course, I looked at the fence that was within easy reach and to be truthful it did not really meet my criteria!  I did not have time to walk/run to a another fence (these horses are typically travelling at 25 mph) so I stayed put and hoped for the best.

Beautiful Bokeh

August 24, 2015 in Information

This lovely shot of a Pied Wagtail by Bob Brown illustrates how good bokeh is favoured in a nature shot, picking out the subject clearly.

This lovely shot of a Pied Wagtail by Bob Brown illustrates how good bokeh is favoured in a nature shot, picking out the subject clearly. A 500mm lens with 1.4x converter was used, giving 700mm and a very small depth of field.

Bob’s picture illustrates very well how a blurred background can help to make your subject “stand out”; it is a favourite technique of nature and portrait photographers especially. A lens which produces a lovely even background blurring is said to have “good bokeh” (we didn’t have a word for it, so borrowed from the Japanese). All other things being equal bokeh is improved by bigger apertures and longer lenses. This is something to watch out for in switching from a full-frame DSLR to a smaller format mirrorless system, as many are doing. You will need to go for faster lenses to get the same bokeh.

Why? Well, a 23mm lens on a Fuji X camera is said to be equivalent to about 35mm on a full frame camera such as the Canon 5D III; the angle of view is the same (your picture covers the same area). But the 23mm at any given aperture will give a less blurred background than the 35mm because its depth of field is greater. To blur the background to a similar degree you will need a larger aperture. This is why the top Fuji lenses tend to be f1.2, 1.7 etc, where the Canon lenses are often content with f2.8. (Bigger apertures put the price and weight up).

A quick look at any depth of field calculator will illustrate this. For example;

Fuji Pro-1 (1.5x crop) with 23mm at f2.8 focussed at 20 ft; everything from 12ft to 57ft is suitably sharp (Depth of field of 45 ft)

Canon 5D III (full-frame) with 35mm lens at f2.8 focussed at 20ft; everything from 14ft to 34.5 ft is suitably sharp (Depth of field 20.5 ft).

You would need to open up the Fuji lens to f1.8 to get the same depth of field, or bokeh.

So this is why the wedding photographer who switched from Nikon 70-200 f2.8 (full frame) to a (roughly equivalent) 50-150mm f2.8 on a Fujifilm camera posted a video declaring that the bokeh on the Fuji lens was poor. It isn’t, it’s physics.

 

Ray Hill

Ray-Hill-web

MEMBER SPOTLIGHT: This week with our lead item we are returning to celebrating last season’s successes. Here we see Ray Hill with some of the nature prints which won him the nature print league trophy last season. Ray’s skills are not confined to nature photos, in his many travels he turns his lens to landscapes too and we could equally as well filled this picture with landscapes and event pictures. We eagerly anticipate Ray’s (and Kath’s) new work next season, it is always exciting and ever improving in quality too. Both Ray and Kath are also members of Mid-Cheshire CC where Ray is also chairman. We featured Kath’s work a few weeks ago – it can be seen, like all front page items, on our NEWS page.

Martin’s Mole (!)

August 17, 2015 in Information

Into-The-Light-MartinSmithWeb

I was taking a walk early one sunny morning when I came across a recently deceased mole on the path before me. As it was in perfect condition the temptation of a photo opportunity became irresistible and I was soon on my knees arranging the subject. With due reverence I placed it as if emerging from one of its hills, beneath which was later to become its final resting place. Normally a mammal’s eyes would give the game away but the mole’s eyes are just one millimetre in size and are only capable of distinguishing between light and dark, all its knowledge of its surrounding world comes from its extraordinarily sensitive whiskers.

Despite being in full sunshine I later converted the shot into a night flash image and resisted the impulse to add a pair of dark glasses. However, I did feel some guilt at not having spent a cold lengthy night of vigil but feel better that I have now confessed. Despite the  ‘Nature’ rules (subject must be alive – Ed)  there are times when deception can become just too tempting.

So if any club members have any dubious images of the creatures of Loch Ness or a Himalayan ape, the nature rules do not apply to open subject competitions. But you will need to do better than a mole in a hole.

Panoramas in Lightroom

August 16, 2015 in Information

The "raw" photos

The “raw” photos

Lightroom CC will now merge photos into a panorama or HDR image. Recently I had occasion to use this feature and was very impressed with the results.

I was using a 35mm lens (50mm equiv.) and could not get far enough away from the church I wanted to shoot. I often just choose a different framing but I decided to make use of the new Lr feature, so I took 4 or 5 shots encompassing the whole building. As you can see I didn’t do anything too technical. I might have made sure of overlap, kept the shots parallel and used manual settings to keep the exposure and focussing the same but I didn’t.

The pictures below show the originals then the completed Lr merge – done as easily as selecting the photos and telling it to make a panorama!

The Lightroom assembled picture

Of course the merging can be done with various pieces of processing software, not just Lightroom,

It has been suggested that you might use this technique in portraiture, but your subject would have to keep absolutely still!

But if you do not have a wide-angle lens available…..
