ToURING THE INTERFACE WITH A BASIC CoMPoSITE 23
You now have two new Read nodes in the DAG (FigUrE 2.4). The first, Read1,
should also be labeled background.0001.png. The second, Read2, should also
be labeled maya.png. This second line of the label is generated automatically by
Nuke and shows the current image being loaded by the Read node.
Let’s view the images to see what you brought in.
5. Click Read2 (maya.png), hover the mouse pointer over the DAG, and press 1 on
the keyboard.
You’re now viewing Read2 (maya.png), which is an image of a little doll. If you look
at the bottom-right or top-right corner of the image in the Viewer (you might need
to pan up or down using Alt/option-click-drag or middle mouse button-drag) you
will see two sets of numbers: 518, 829. These numbers represent the resolution
of this image—518 pixels x 829 pixels (FigUrE 2.5). This odd resolution simply
came about from placing this doll on my flatbed scanner, scanning, and then
cropping the image. Nuke can work with any resolution image and mix different
resolutions together.
FIGURE 2.5 The resolution
of the image is shown at the
bottom-right corner in the
Viewer.
FIGURE 2.4 After
bringing in two files,
your DAg should look
like this.
Note If the file called
maya.png isn’t Read2,
you did not complete the
steps as presented. This
is not necessarily a problem,
but you’ll have to
remember that my Read2
is your Read1.
Let’s look at the other image.
6. Click Read1 (background.####.png) and press 1, like before.
This image you are looking at is part of a file sequence. It’s a rather dark image
of a painter’s toolbox. I shot this image in HD, and indeed if you look at the
same corners of the image in the Viewer, you can see that the resolution for this
sequence is 1920x1080. Since this is a defined format (more on this in Chapter 8),
the bottom-right corner displays the name of the format rather than the resolution.
The bottom-right corner shows HD.
Your goal in this chapter is to place the doll image inside the artist’s toolbox—and for
it to look believable. Let’s start by placing the doll image over the background image.
