Digitat Photographic Practice. Ex.11. Raw.

Daylight image. Raw.
Taken early pm.
Camera settings: f8 @ 1/200
                          ISO 100.
                          WB Daylight.
The WB 'Daylight' setting was in my judgement
too warm. This I initially changed from 5500k to
4300k. Still not happy with the result, I used the
WB dropper clicking on the grey tarmac. This
 reduced the colour temperature to 3850k which
 closely matched the scene.
At set exposure there is a very slight highlight                             Cannot display Raw files
clipping of the gable boards of the roofs and
slight loss of detail in the shadows on the                                    Web will not transmit anything larger than
bottom left. The loss of shadow detail was                                  a jpg.
corrected by the 'Black' slide and the highlght
clipping was eliminated by applying the 'Recovery'
slide. Contrast was increased to 50%.
None of the other facilities on the Raw document
provided a useful contribution.

Daylight image. JPG file.
Taken early pm.
Camera settigs as above.
Opened 'Curves' and established mid point with
dropper tool.
Increased contrast slightly by steepening curve.









Dynamic Range: There is no discernable difference. Both have insignificant amounts of highlight clipping
                          and loss of detail in one of the shadow areas.

White Balance and Colour: The use of the dropper tool in 'Curves' provided an identical WB and colour
                                           match in that of the jpg as that of the raw image.

Local Adjustment: If any had been required there are probably more available in the jpg format than the raw.
