Lightroom is a photo management software that allows users to edit and organize photos. Raw files are the original digital files taken with a digital camera. They are not processed or edited in any way, and contain all of the data captured by the camera. DNG is a file format used by Lightroom that preserves all of the data captured by a digital camera, including raw files. DNG was created as an alternative to JPEG, which is the most common file format used on websites and for email attachments. DNG is more compressed than JPEG, which makes it faster to download and upload. There are several reasons why Lightroom might convert raw files to DNG. One reason is that DNG is more compressed than JPEG. When photos are converted to DNG, they take up less space on your hard drive and can be sent over the internet faster than photos in JPEG format. Another reason is that Lightroom can better preserve the data in raw files than in JPEGs. Raw files contain all of the information captured by a digital camera, including details about how light affects colors and tones. By converting raw files to DNG, Lightroom can keep this information intact while still saving the photo on your hard drive as a standard image file. ..
