Exercise 8 – Tungsten and fluorescent lighting
I have only done a part of this exercise so far, so will add to it in time. To begin with I have looked at the differences made by fluorescent lighting.
This is the room where my morning drawing class is held (a local village hall) and the fluorescent lighting gives poor light actually as well as in a photograph. I found myself wanting to add more clarity in the photograph just as I want to add a more natural light when I’m in the room!
This was with the compact Ricoh on program mode and it gave ISO 400 @ 1/124 f/2.5. Auto-white balance gave a temp of 4000K.
I altered this in Photoshop to Fluorescent which gave 3800K so pretty similar and this gave the most realistic colour quality to me. I tried the other settings as well but they looked even more odd.
I also took a photograph in the town centre as twilight was just falling.
Again on Program f/1.9 @ 1/100 with auto while balance which gave 5350 (almost the daylight setting in Photoshop). The natural light outside looks reasonably okay, although a trifle dull, but the fluorescent lights in the Keelans shop look very orange.
I then changed the white balance in Photoshop to the fluorescent setting (3800K):-
The fluorescent lights in the Keelans shop now look more natural but the natural light outside is very blue.
In this kind of situation you obvious have to make a decision as to which white balance setting is best utilised, depending on the subject. Another way round it might be, for instance, to take a picture like the above using auto or daylight white balance but then, in Photoshop to do a copy utilising fluorescent white balance. The two could then be combined.
