LEARNING

Understanding Photography

This article explains how to execute the

first steps in the workflow for developing

images. These are applying lens

corrections, straightening images and

correcting perspective. The last two are

optional and are not needed every time.

You have also seen how to correct colour

casts that might occur due to improper

WB settings.

I will conclude by reminding readers

once again that all the operations

described in this article including

straightening and cropping are fully non-

destructive and you can change any of

them whenever you wish!

CONCLUSION

Picture 5-7 shows an image before

and after the WB correction.

This shows how important WB

correction is.

Short cuts: Table 5-1 gives you

some shortcuts to help you use the

Develop module efficiently. |SP

Next month: You are now ready to take up tone corrections. This will be the topic for the

coming month.

Table 5-1 – Shortcuts

Shortcut What it does

X key Toggles the cropping overlay from Landscape to

Portrait format and vice versa.

W key Invokes WB Selector tool (Picture 5-7↓2).

I Key Toggles information overlay (Picture 5-7↓7).

Picture 5-7: The subject was photographed with

incandescent bulb WB when the light source had

a colour temperature that was higher causing this

blue cast (5-7↓1). A single click with the WB Selec-

tor tool (5-7↓2) on the gray card (5-7↓3) was all

that was needed to correct WB (5-7↓4).

You can also get the same effect through the

alternate method of selecting a preset WB (Picture

5-7↓5) and then fine tuning with Temp and Tint

sliders (Picture 5-7↓6).
