Lossless compression
An image-compression scheme, such as TIFF, that preserves all image detail. When the image is decompressed, it is identical to the original version.

Lossless compression. When an image compressed with lossless compression is uncompressed, its image quality matches the original source—nothing is lost.
Lossless audio formats
Lossless audio formats provide high-quality audio because they don't loose data during the save process.
Lossless - Means that a particular compression process used does not decrease the quality of the image in any way.

Lossless compression
Reduces the size of files by creating an internal shorthand that rebuilds the data as it originally were before the compression. Thus, it is said to be non-destructive to image data when used.
Lossless compression - A type of file compression that reduces file size without losing image date. PNGs and GIFs are common lossless file formats.

lossless compression
a compression technique that will retain all of the file's original image characteristics. The perfect lossless compression technique remains elusive.

lossless encoding
A data compression or encoding algorithm that does not lose or discard any input data during the encoding process.

Lossless Compression
Software algorithms (and accompanying file formats) used for reducing files sizes were data is not discarded during compression and can be fully restored when decompressed.
lossless compression
A compression algorithm that reduces a file size but does not lose any information. The uncompressed image is identical to the original.

Low Pass Filter - Most digital SLR cameras employ a Low Pass Filter (LPF) or Anti-Aliasing (AA) filter in front of the imager to help eliminate color aliasing (moire) problems.
Lossy/Lossless files
When a digital camera takes a photo, the image data is stored on a memory card as a computer file. If the data is stored fully, the file is called a lossless file. These files are quite large in size.
Lossless compression - used by a file format such as TIFF - does not discard any of the original image information and retains an exact copy of the photo.

There are also lossless ways of saving files using TIFF (Tagged Image File Format) . These keep all the original information, but at the cost of much bigger files. TIFF files can be compressed in a non-lossy way, but they don't get very much smaller.

TIFF is a form of lossless compression. This means that when an image file is TIFF formatted, none of the original information is lost. Consequently, exact replicas of the original can be made from TIFF files.
Photoshop and TIFF formats are lossless, but are very space intensive ways to store images. They also don't correctly represent vendor specific information. Then there are Raw files.
There are two general types of data compression: lossless and lossy. Lossless compression has the advantage that no data is lost. So, lossless compression does not degrade the quality of images.
The compression technology used by WMP is "smart" in that it supports both lossy as well as lossless compression since it is possible to process only part of a large picture file to show a smaller version.
When a compressed image is reconstructed (uncompressed) and the pixel values are identical to the original image, the compression is known as lossless.
However, some camera manufacturers may use lossless or slightly lossy compression to reduce file size. Lossless compression is where the image is compressed, but no information is lost.
Lossless compression is applied to reduce file size slightly without compromising any quality. RAW image files must be processed with special software before they can be viewed or printed.
Developed as a patent-free alternative to GIF, the Portable Network Graphics (PNG) format is used for losslessly compressing and displaying images on the World Wide Web.
Modern systems tend to store the data digitally, often with lossless compression. The difficulty with this approach is that the data is fragile, the format may be archaic, and the data may be easy to falsify.
Lossless techniques compress the file without removing image detail or colour information; lossy techniques remove detail. JPEG is the most common file format in digital photography but this is a "Lossy" file format.
Nikon says that compressed NEF files are "virtually lossless" but they sure do take a long time to write to memory.
There are two types of compression: lossy and lossless. Lossy compression (JPEG is an example) can result in visible degradation of image quality, especially when saving the same image as a JPEG multiple times, ...
Is considered a "lossless" format, since the image normally uses no compression, and loses no more data than the initial conversion from 12-bit to 8-bit in the camera's software.
I check Compressed (you can see it's lossless and I see no reason not to check this), Embed Original RAW File (in case I want to extract it as some future date), and JPEG Preview: Medium Size. I leave the Convert to Linear Image box unchecked.

It is a file format with good, lossless compression for images with low color depth (up to 256 different colors per image).
TIFF stands for Tagged Image File Format, and it can be a lossless compression format.
Tagged Image File Format is a lossless, uncompressed image file format. A given image in TIFF is usually a much larger file than a JPEG for example, but a TIFF file can be manipulated in editors like Photoshop without loss of quality.

TIFF is an industry standard non-compressed (or light lossless compression using the LZH protocol) file format. It produces giant files, though.
Another advantage of RAW is that it is a lossless format. This means that the image does not lose any quality or information (unlike JPEG). As a result, RAW files are much larger than their JPEG counterparts, bringing me to.
