I believe enhance photos are very important and makes your cakes and other ********** items more beautiful/attractive. Does anyone know of any tutorials in photoshop do do so? thanks

I don't know of any photo shop tutorial, but if you Google Photoshop Tutorials you will find that there are loads of websites on the subject - many of which offer free tutorials.

I usually open my photos with Microsoft Office Picture Manager for basic editing, such as auto correct, adjusting contrast and brightness etc -  to name just a few of the program's editing features.

Hope this helps!
