They knew how to separate a PDF into parts.
But as the old saying goes, to someone who only has a hammer, everything looks like a nail. Many readers have already concluded this was not the right approach. Of course, on the recipient end, they have received the document split into pieces and those lawyers will be assigning someone to combine the pieces back into a single file. But the team has dealt with this situation before and someone remembers that the solution is use Adobe Acrobat to break the large file up into smaller files and soon the three 15 MB PDF files are on their way, sent by separate emails. Their email system does not allow an attachment that large. A legal team scans a huge document of 100 pages because the lawyers need a digital copy with original signatures or a court filing stamp. Another option is BMP with compression, which gives some file size reduction without any loss of detail.It happens too frequently even today. With scanners you can select TIFF (TIF) for that. However, high-end cameras let you save all the details in a RAW format. Most cameras and scanners default to producing JPEG files, without any noticeable loss of detail. However, the more compressed a JPEG file is, the more fine detail you lose. JPEG (JPG) files are usually the smallest. AT the same resolution, black & white makes the file 8 times smaller, greyscale about 3 times.Īnother thing you can do is to change the file format. However, if you are scanning text or line art, you can set the scanner to Black & White or Greyscale. ALso, many email systems limit the size of an email to 10MB, so an email with just a few full-size photos might be rejected.

The person recieving the email will be able to see the photo in full quality, and my email program does not have to send so much data. When sending photos by email, I usually reduce their size to something like 1200x800 pixels. An image that is 10" long only needs to be scanned at 192dpi. In other words, for most current screens 1920 x 1080 pixels. If you are scanning to view the image on the screen you only need as many pixels as are visible on the screen. For any other colours, the printer will put dots of those 8 colours side by side, and the eye will integrate them into a shade.

This is because the scanner can see 16 million (or more) colours in every pixel, but most printers can only print eight colurs: the cyan, magemta and yellow inks, mixes of them (red, green and blue) plus black and white. You should almost never have to scan at the printer resolution. If the print is half the size of the original, you can scan at 150dpi but, if you will print at twice the original size, the scan needs to be 600dpi. If the print is the same size as the original, you need to scan at 300dpi. This means that, if an image is printed with a size of 2", the scanned image only needs to be 600 pixels. Commercial printers usually request images at 300dpi. Once you go below 150dpi you will start to notice the degradation. To print an acceptable image it only needs to be about 300dpi (dots per inch) and even 200dpi is quite acceptable. This can be done at the scanner, or in the scanning software. The main way to reduce the size of scans is by changing the resolution.
