4 In the Paste dialog box, select how you want to paste the Adobe Illustrator art and then click OK:
Smart Object Pastes the art as a Vector Smart Object that can be scaled, transformed, or moved without degrading
the image. As the art is placed, its file data is embedded in the Photoshop document on a separate layer.
Pixels Pastes the art as pixels that can be scaled, transformed, or moved before it is rasterized and placed on its own
layer in the Photoshop document.
Path Pastes the art as a path that can be edited with the pen tools, Path Selection tool, or Direct Selection tool. The
path is pasted into the layer that’s selected in the Layers palette.
Shape Layer Pastes the art as a new shape layer (a layer containing a path filled with the foreground color).
5 If you selected Smart Object or Pixels in the Paste dialog box, make any transformations you wish, and then click
Enter or Return to place the art.

High dynamic range images
About high dynamic range images
The dynamic range (ratio between dark and bright regions) in the visible world far exceeds the range of human vision
and of images that are displayed on a monitor or printed. But whereas human eyes can adapt to very different
brightness levels, most cameras and computer monitors can capture and reproduce only a fixed dynamic range.
Photographers, motion picture artists, and others working with digital images must be selective about what’s
important in a scene because they are working with a limited dynamic range.
High dynamic range (HDR) images open up a world of possibilities because they can represent the entire dynamic
range of the visible world. Because all the luminance values in a real-world scene are represented proportionately and
stored in an HDR image, adjusting the exposure of an HDR image is like adjusting the exposure when photographing
a scene in the real world. This capability lets you create blurs and other real-world lighting effects that look realistic.
Currently, HDR images are used mostly in motion pictures, special effects, 3D work, and some high-end photog-
raphy.
