TEXTURE

REVEALING TEXTURE.


PREVIOUS NOTES

Texture is the quality of the surface of the object
you are photographing. It maybe rough or smooth
Texture levels can be very extreme such as a smooth
surface to a rough coarse grainy surface.


It is important to consider the angle in which you are
taking the image to capture the texture of the object
Too shallow a view may mean you miss the some of the
detail on the object. It is important to consider to use
a reflector to lighten the shadow to ravel the texture.

f10 20 sec

I was struggling to get the angle of the light correct so

that I could highlight the strands of the curved area

of the shell. I then changed the static flash for a

hand held tungsten light and then set the expousre

levels to 6 sec and experimented with painting the

light onto the shell to acheive the ideal lighting

to show the contrast of shadow and light

on the strands.

I ended up extending the exposure time to

reduce over exposure issues on areas

close to the light.

front left silver reflector

f14 1/60 sec

I like the deep shadows on the left side

I think i should have moved the light slightly

forward as I would have prefered to show

more light on the strands on the curved section

of the shell

f 13 1/60 sec

I used and extension tube to try to capture

the texture of the shell close up but struggled

to get the light correct. As the lens was close

to the subject I had to move the light to

side to ensure light was falling onto the

shell to achieve good exposure. I could

struggled to get the contrast levels of

light and dark to highlight the texture

details.

silver reflector under subject

This is the effect that I wanted to achive

but this image has been darkend in

photoshop as the original image

was too bright. I put the reflector

under the subject to highlight the

strands.

I did not submit this image as I think

it has been too over processed in

photoshop.

I wanted to try to seperate the texture

from the shell body so used the tungsten

light to higlight the texture only.

I don't think this worked out as well

as I had planned.

I wanted to do too images for texture one with

ambient light and one under artifical light.

I set the subject in front of a window in late

afternoon  when the sun was low in the sky.

I blocked to light from the left and

only used the sun from the right that

I then reflected onto the texture of the

shell. I liked the use of the light but

felt that light was too soft and the

subject was too flatly lit.

I then moved the subject and re shot

F20 1/8 SEC

After experimenting with diffused lighting
from the side I felt that the shadows were
too soft and so did not show the true texture
of the object. I also felt that using a white
diffuser also reduced the shadows so choose
to change the lighting set up to be harsh
lighting to create deep shadows in the shells
grooves. The set up was in a room that had
a big window on the right side of the object
this was creating too much light on the right
side so I added a black card to the right
side to create a deep shadow in the grooves
to enhance the textures.
I used a fixed tungsten light on the
left side. I moved the light around to
the correct angle to create highlights on
the ridges of the shell pattern.of light and dark.
I then experimented with exposure time and
choose to the exposure level which was one
stop under the my original setting.
I added a silver reflector to the back of the left
side to add light to the rim of the shell as it
was too dark and it also create a sense of
depth to the image as it showed the difference
been the inner and outer shells.

MONOCHROME PROCESSING

I wanted to try to capture capture

the texture effect of both the shell

and the slate surface I was photographing
it on.


I placed a black card over the window
to block out the light coming from the
left side of the subject to create contrast
of both light and dark and create some
shadows to highlight the textures.


I also experimented with exposure levels
as I was concerned about not over exposing
the shell surface which was reflecting the
low evening sunlight.


I processed the image as monochrome as
I think it ascetically shows the texture
levels better.
