Hi
As you can see from these 3 images, The composite with basic color curve with contrast works fine as in the first image.
watch image on the left screen, it shows alpha transparency as unaffected, you have to keep in mind that when you mangle it out of proportion the alpha transparency is also affected and this is going to color the merge over.
In Image 2 you can clearly see on the left screen that the transparency channel is affected and that's going to color the merge.
Now if you have messed up the alpha transparency, no problems, this is where the Node based compositing really shines.
you can extract the alpha Transparency from the original Image and re-apply it to the merge using Bitmap node.
You have to keep in mind that Node based workflow works a little different than a time based workflow, both have their advantages and disadvantages.
Node base you have more control, but you will come to appreciate the extra control as you try to wiggle out of tricky situations and complicated and complex composites.
