When I process the image with Noiseware, the resulting file is much smaller than the original. How can that happen?

There are two reasons why the resulting file might be significantly smaller than the original:

- First involves the JPEG compression level, which by default is set to 90%. You can change this value from menu View->Options->Jpeg Quality. Once you set it to 100% the size of the file may increase up to two times.

- The second reason is that noise is generally very hard to compress, and noisy pictures result in larger JPEG files. Once noise is reduced the compressed JPEG files have a smaller size, and depending on the amount of noise suppression applied, the file could get much smaller than the original.

However, if your original image is a TIFF file and you save it as a TIFF file, the size will not change, since the size of a TIFF file is the actual representation of the pixel count and it does not implement any compression mechanism.

If you need higher quality prints, we recommend either to set the JPEG quality to 100% or to save file as a TIFF (the latter is a lossless format). For more "film" like images, we recommend setting the overall suppression amount to no higher than 80%, and for High frequency noise, to 60-70%.
