Need software Computer was in for repairs and I lost several programs including the software for my camera. I downloaded the existing photos on the camera, but cannot work with them, i.e. cropping, color enhancement and etc.

With all digital cameras the maker delivers a CD (DVD) with software to install on your computer. This makes it possible to put the pictures from the camera on any computer. On the disk(s) are drivers for all operating systems that need them. (Windows 7 and up do have all drivers for hardware that is certified by Microsoft) And there are programs to download the pictures from the camera to the PC. Sometimes the manufactures also delivers software to organise the pictures in folders and software to view or even enhance the pictures you shot.
When you lost the disk, most of the time you can get the software on the website for your brand. Sometimes you even get newer, updated software and new drivers if needed.
If you can't get software form your brand, you always can install other generic software like Ulead, Pixir, BeFunkey, Gimp, Photoshop express. Or if that is not possible you could install an external memory card reader and download the pictures via de memory card reader.
