Colour into tones 2

I’m not at all sure that I’ve got this exercise right but I have discovered some interesting effects just the same.

I already knew that increasing the slider, or strengthening the filter on any given colour weakens that colour, that the reverse is also true and that has an impact in the atmosphere of the scene.  What I discovered in this exercise is that although there was not a great deal of yellow in the image, the yellow slider had quite an impact in cutting through the effect of haze giving, thus more depth to the image.

The exercise asked us to choose between three scenes with the aim of achieving a specific effect.

I  opted for a landscape scene in which I was to ‘ emphasize the depth (aerial perspective) by strengthening the visual effect of haze.  My interpretation of this was the that I should make the haze seem stronger or more dense by manipulating the appropriate sliders and that this would give the image more depth.  I tried this on several images with very little  success.

Although in each case I was able to make the scene more dramatic and maybe deeper, the actual haze itself is reduced.  In what I would consider the most successful image, I have manipulated a number of sliders:

  • increased red and orange, the orange increased the highlights on the trunk of the tree
  • increased yellow – this cut through the haze and brought the background trees back into focus as well as boosting the highlights in the tree overall

  • reduced the blue which brought all of the detail back into the sky, it also reduced the haze even further.  Had I increased the blue, I would also have increased the haze but lost the detail in the sky and I preferred the more dramatic effect.

I posted a question on the OCA forum regarding this exercise as I’m sure I must be misinterpreting the instructions.

Very swift response from  Eileen, yes I probably have got it the wrong way round, not clear though.  Here is the opposite result with the scene lightened to emphasize the haze.  Not sure that it gives the impression of more depth though!  But then again maybe it does.

I live in Gloucestershire with my husband Iain and West Highland Terrier, Isla. I enjoy golf, photography and my grandchildren, not necessarily in that order! Having completed a 10 week digital photography course with the Open University in 2010 and wanting to take photography further, I enrolled on the Open College of the Arts BA (Hons) starting with 'The Art of Photography' which I thoroughly enjoyed. Next came Digital Photographic Practice followed by People and Place. In April 2016 I progressed to level two with Documentary and in June 2018 enrolled on my latest OCA course, Landscape.
