Pardon me for making the title that long. I had to include the “Photoshop Bitmap Mode” thing in, to emphasize that these images are not just ordinary bitmapped or raster images. They are TIF images in Photoshop Bitmap Mode. The former is just any kind of raster (pixel) image. However, when we refer to a “Bitmap” image, it is an image that is in Photoshop Bitmap mode — one that has nothing but black and white pixels. We also call these bi-level or 1-bit images, because each pixel is described with a single bit of information (on/off, black/white).
You can save Bitmap images as TIFF, EPS, or PSD. If you import a Bitmap image into InDesign or Illustrator, the white pixels are treated as transparent areas and the black pixels knock out any color behind them.
Here’s a sample Bitmap image taken from today’s freebie package. I imported it into InDesign and placed it halfway against a colored background.
You can see that the white pixels are transparent. The Separations panel easily shows us that it is knocking out the colored areas behind it.
You can also do a lot more with these bitmap images. You can colorize these kinds of images just like grayscale images: Just select the image (not the frame) using the Direct Selection tool (the white arrow) first, and apply a color from the color swatches palette.
You can also knock out colors beneath it or use different blending modes in the Effects panel (InDesign transparency palette). With preview on, you can see how color blends against the background.
These images are in 300 dpi resolutions, which should be decent enough for most print design projects. Also, this is just part 1 of our Antique Art Bitmap Images collection series. More of these will come in the next few days.
Sample thumbs of all the images in the package are shown below. Download link is also provided below. Enjoy.
