4.1 The Electronic Light Table
TargetPro’s Electronic Light Table (ELT, for short) is a dialog box where you can
make a wide range of sophisticated modifications (enhancements) to images.
Image enhancements can be in the form of:
• increasing or decreasing brightness, contrast, gamma and sharpness
• emphasizing or de-emphasizing content by applying unique “filters”
• applying vignette lighting corrections
• rotating the image clockwise or counterclockwise
You can preview your enhancements in ELT before applying your changes to
your contact image. TargetPro images benefit most from files that have Tag 270
information in them. However, if an image does not have Tag 270 information,
you still can put the image into the ELT – you just won’t be able to mensurate the
image.
1. Open a file in TargetPro: File→Open
2. From the main menu, choose Tools→ELT (or click the ELT icon
pictured in Table 4, ‘Group Four: Image Management Icons’).
TargetPro copies the image into the ELT working window as a thumbnail view of
the original image, where you can modify the copied image and preview the
results. You can then decide to accept or reject the enhancements by applying
or not applying the enhancements to the original image. A typical screen of this
kind is shown in Figure 15.
Note: Any changes you make here are temporary and will not affect the
underlying image you opened in TargetPro unless/ until you choose to click the
‘Apply to Large Image’ button in the ELT.
