PhotoLine can load raw images from digital cameras

Many digital cameras can save a so-called RAW format. This format saves the raw data that come “directly” from the sensor of the camera. This format has some advantages and disadvantages compared to other file formats. The main advantage is, that the images are relatively small and there are no compression problems. You avoid problems with the automatic color correction of the camera, too. The disadvantage is that every camera has its own raw format. So you have to search for an application, that can read the format of your camera. If you have such a software, you will see, that you have to spend some time to get a perfect image from your raw data.

Why raw images?

Some people claim that the quality of raw images is not better then JPEG images. We don't think so. If you only spend time for a quick view on both kinds of images you won't see a difference. But if you want to manipulate your images, raw images are the better choice. One advantage is that raw images normally have 12 bit of color information per channel. If you want to lighten such an image you will get a far better result then lightening an image with only 8 bit.
Beside this, you can get problems if you have to work on images that where compressed in JPEG format because of the JPEG artefacts. If you got a noisy image from your camera, the JPEG version of the image will be so artefacted that it will be much work to remove that noise.

JPEG Image
The same image with 800% zoom but JPEG compressed (relativly high quality - 70%)

Loading of raw images with File/Open;

You can open your raw photos using "File/Open" in PhotoLine. To get a better quality this way you can setup the loading at "Edit/Options/File/RAW".
Options for Raw-Import

After you loaded the photo you can use all tools in PhotoLine to get the best result.

PhotoLine uses a library to load digital camera raw images. This library can load almost every raw format.
