South African Art & Photography

At PrintWild we are continually striving to empower the industry, and have thus created a platform for local photographers and artists to showcase their talent and their work. This platform is called Digital Gallery.

This division of PrintWild was launched at the Photo and Film Expo 8 months ago and has grown tremendously. Digital Gallery exhibits some of South Africa's top artists and photographers' work and uses PrintWild's proud history of exceptional online printing to deliver these works of art straight to your door, ready to hang.

From next month, PrintWild and Digital Gallery photographers and artists are coming together to help create an easy and affordable method of decorating your home or work space. We will be showcasing one photographer/artist a week, discounting all their products. The featured artist’s special will run for one month.

If you are an interior decorator or interested in improving your home, this is an offer you will not want to miss.

Calculating The Aspect Ratio Of Your Image

Every now and again, PrintWild receives a query regarding the size and aspect of an image. In the last week, a client sent us this question:

The website requires me to select a size/dimensions for the print. I have an idea of the size I am looking for (say 1m in height..). However, I am not sure which of the size options to select as I do not want the image to be distorted and am not sure how to scale the image. How should I proceed?

 For those of you who are struggling with the same question and have been putting off ordering a custom size print, the image below will help you understand how to work out the corresponding height or width of any photo if you need to change the size...

Here's an example: If you want the width of this 14cm image to be 16.5cm, draw a diagonal line from corner to corner of your image (just like the red line in the image). The height will be where the blue lines meet, in this case 11.8cm.


Now that you understand the concept, there's a mathematical formula to help you work out how to do this (without drawing all over your image and taking the time to find the nearest millimetre).

Current height ÷ current width × desired width = desired height.
10 ÷ 14 × 16.5 = 11.8 cm
  
If you need to figure out the desired width, just switch height and width around.

 
GOOD LUCK!

Our Fathers' Day Photo Competition

For the last month PrintWild has been running a Facebook competition asking followers to submit pictures of their Dads in action - either playing with his kids, fishing, in his element at the braai, enjoying a good game of rugby - doing what he loves.

A R500 PrintWild gift voucher was up for grabs to use towards any photo print of their choice.

The winner has been announced... Congratulations Sue Carruthers! This is the photo she submitted: 

  

We had so many stunning entries, it would be a waste not to show a handful of them:

From: Adele Klusener

From: Glynis Eggleton

  
From: Petina Ingle

  
From: Chantelle Flores

From: Retha Groenewald

Thank you to all of our entrants for their beautiful photos! Wishing you all a very happy Fathers' Day.

The World of Colour Correction - One of the most intricate and complicated worlds to live in

After a rather long sabbatical, PrintWild is back in action and ready to take the blogging world by storm!

Paul (Snr) Changuion wrote this article on his experience over the last few weeks with colour correction:

"Having spent many years correcting and printing colour images, the past two weeks have been really interesting. Colour management is a huge subject and would take volumes to explain fully.

Three weeks ago I went for a a simple eye check up with Ophthalmologist Dr Malcolm Carey of Ballito. 

The bottom line was that I had lens replacements in both my eyes.  After the first implant (in my left eye) I noticed the new lens was about 40% sharper than it was through my year-old prescription specs.  More surprising was that my left eye seemed to see about 5% bluer than the untreated eye.  After a day or so the colours seen by both eyes were once again in agreement.  Another anomaly was that all colours appeared more saturated.  Finally this Tuesday the right eye lens was replaced, which produced the same colour cast as the left eye in the first 24 hours and by Wednesday evening my sight was amazingly sharp and comfortable.

This fascinating experience prompted me to ask Dr Carey a few questions:

Question 1:  What colour lenses did you put into my eyes?
Answer:  The implant lenses apparently do have a yellowish filter, to protect the retina from mostly invisible blue and ultraviolet rays.

Question 2:  Does the brain compensate for colour cast in light sources? For example,  I once spent some time in a green Porta Loo when following the Umzinduzi Canoe Marathon and when I eventually emerged, everything seemed, for a while, to have a magenta colour cast.  Another example was driving a car with the top section of the windscreen having a green anti-glare tint.  This had the same effect.  For a while after that, having left the car, the blue sky had a magenta cast.
Answer:  This was because the brain had in the false light conditions compensated for the colour cast produced by the green.  The green sensitive photoreceptors (cones) had increased activity in a green environment and then a degree of photoreceptor “exhaustion” had occurred. This led to an under representation of green once in natural environment. (One should always minimise time in portaloos for obvious reasons!!!)


Question 3:  Is there a method to test an individual’s colour sensitivity?
Answer:  The most sensitive  test  is called “Farnsworth-Munsell”.  It’s time consuming and would be expensive to run, but would give one a clear summary of an individual’s colour perception, or in our terminology, our very own colour profile/gamut.  The results would produce a graph very much like the colour gamut produced when profiling a printing paper.

Question 4:  How varied does colour appear to different people? 
Answer:  Generally, on average, women are more sensitive to colour variations than men are. (Men are more likely to have a degree of colour blindness which can vary from mild to complete - this is usually RED- GREEN. Female colour blindness is less common but when present, is usually more severe).  Dr Carey did not have any survey statistics available, but said a rough estimate would be that only 30% of people could differentiate finite colour casts. 

This begs the question:  How do we judge the colour in images when editing them for print?

The starting point would be to use a good IPS  (In-Plane Switching) monitor. Your monitor should be calibrated with a monitor calibrator, i.e. a Spyder Display Calibrator.

As explained in a very informative article: “IPS displays were designed to improve on the flaws of LCD technology, primarily in regards to the poor viewing angles and colour reproduction. They do this by simply altering the direction of the pixels within the display (parallel instead of perpendicular pixels). Of course, it really isn’t that simple and neither is explaining it. So let’s just leave it at that ;)”

Below an IPS display remains stable when viewing from an angle, as opposed to the next illustration of an LCD display viewed from an angle:

And finally, below are two images that show the difference in colour on screen and in print:"


Thank you so much for the insightful article, Paul!
