Project 37; Filters with black and white film.

I do not own a film camera so I have done this project applying the black and white adjustment in photoshop CS3 and selecting the various filters available from the drop down menu in it.

Firstly here is the original colour image shot in RAW then transfered into black and white.

Here is the straight conversion no filter applied. This is really the control and all others need to be compared to this to see the changes.

No filter. On the right Yellow filter applied. Note the yellow pepper on the right is lighter. Also see the change in the green pepper caused because green is a combination of primaries yellow and blue.

No filter and on the right we have with the red filter, the change in the red pepper is most obvious, it is lighter. The green is still lighter than the control but this could be changed using the green colour slider.

Again, no filter applied on the left and a blue filter applied on the right.

Although the results are not exactly the same it might take a little tweaking to achieve the same as the examples given. Still the principle can be seen.

Project 36; Warm and cool colours

A warm pair here, not as similar or as warm as the next combination.

Very definitely a warm pairing, not really contrasting but very similar. I was attracted by the warm oriental feel to theses.

A cool pairing of green and blue here with the red standing out between. Also the snow adds a chill.

A coolish contrast here although the violet almost strays into the red. Here I wanted to show flowers.

A cool-warm contrast. I saw this colour combination and the angle on the building made it all look a bit surreal.

Project 35; Colour relationships

Complementary Colours; Violet and yellow.

Above the example on the left is closer to the proportions as described of 1:3. The second image has the proportions reversed. I find the first more pleasing, perhaps because in the second I look first at the yellow flowers and almost miss the violet ones altogether.

Complementary colours; Red and green.

Here the proportions are roughly 1:1.

Above we have a contrasting combination of red and blue with more blue than red I think even though the pink is actually light red.

Again a contrasting combination. Blue goes well with yellow I think in this case anyway. Is it that the proportions are right here?, the contrast between a dark blue and a bright yellow really works well together. Also its a cool warm contrast.

This time a warm contrasting pair of yellow and red. The green here is a yellowish green and the black background works very well to make the two main colours stand out.

A multi-colour combination. There are many colours here. The nuetral grey of the wall at the bottom and the white of the sky sort of frames the others. Below the white of the cloud we have blue sky and then many colours in the houses. Yellows and oranges on the right, then red then yellow again. Also the houses themselves are multi coloured. the shutters on the orange house are blue making this a complimentary combination. The house on the bottom right is yellow and the shutters are green making this a contrasting combination.

A contrasting combination of orange and green. There are also neutral colours here, white and black. Orange is the stronger colour here but the proportion of green to orange is about right I think, about 2:1?

Project 34; Black, White and Gray as colours.

Black;

Average exposure on the meter. 290 or 300 in photoshop.

White;

the above is the first in the series, taken at the average reading on the meter. It appears more gray than white. There is a blue colour cast. The reading in photoshop is about 256 on the liminosity scale.

More grey than white again but light grey. In photoshop checking the colour, the square becomes more white from left to right. The readings are just under 253 on the left and just over on the right hand side. It is also becomes more white from bottom to top. There seems to be a slight blue or violet colour cast.

Again Light grey rather than white. Reading in photoshop is between 248 on the bottom right and 259 on the top right. Again a slight blue colour cast.

Still grey. The reading is 253 in photoshop.

Grey;

249 in photoshop so technically not grey!

290 in photoshop. one stop higher.

Another stop higher. No big difference in hue, around 290 to 298.

Similiar reading in photoshop.

Project 33; Secondary Colours

Orange;

Above orange on a Munsell colour chart.

Here are some orange coloured fruit and vegetables photographed on a neutral background. This is the metered average exposure.

Here is a half a stop opened.

And here is half a stop under.

Heres one I made earlier;

Violet;

A square from the munsell colour checker.

Crocuses at an average meter reading. A small detail on an ornamental garden pump. At average exposure.

A half a stop open. .

And a half a stop darker.

A small detail on an ornamental garden pump. At average exposure.

1/2 stop up.

1/2 stop down

Green;

I realise this is not the green in the colour chart, nevertheless it is green if a little more to the blue side on the colour wheel. This is an averaged exposure, in the centre on the light meter.

One stop down.

One stop faster or up

Project 32; Primary colours

Above yellow on a Munsell colour chart.

I cannot think of anything more yellow than a lemon. Here I shot at 1/60 second at f4.5. I think the colour here is close to the yellow on the colour wheel.

again at 1/60th of a second but at f 4.0. The colour differnce between the two shots is very hard to discern but i think this is closer to the yellow on the colour wheel.

Here at 1/60th of a second but f5.0. the yellow here is a little towards green, the colour temperature is lower than the other two shots.

Here is blue as on a Munsell colour checker chart.

Blue sky at the average meter reading, light blue.

One stop slower, slightly more exposed. Very light blue.

One stop faster, slightly under exposed. Darker than the patch.

Red on the same chart.

Again a brackets series of reds but none match the colour checker. All see too blue

So here I have adjusted the colour temperature to 5500. The others are all at 3550, which must explain the blueness of the colour, its almost violet. This is the closet to the colour patch.

Its crazy how much colour varies to the eye. I would have assumed that it was easy to find close matching colours to the colour circle but not so. White balance seems to have a big influence but right now I am not sure how.
