I'm not exactly sure what you want to do. There are probably many ways to remove a reflection. Most of them require some editing knowledge. So, to get the result in the following screenshot, I used a couple of methods.
- On the top edge of the box, I used a Quick Selection tool to select the right-hand part of the box edge, then used Ctrl+J to place my selection on a new layer. I then manipulated the new layer and placed it over the portion of the top edge containing the reflection. I actually did this several times to place a number of small pieces in place. The manipulation also required reversing and mirroring the pixels to fit the curved edge of the box.
- For the right hand disc within the box, I selected a circle around the top, created a new layer from the selection, turned the circle of pixels around so that the entire disc would be covered without a reflection, then used a mask to block out the reflection.
- Perhaps the easiest way would be what I used on the left hand disc. I created a new layer, used a brush to paint the main item color on the new layer, then used a blending mode to make the item more realistic. Here, I used a lighten mode.
- Another method would be to use the Clone tool to copy pixels from one area to another.
This is a somewhat crude result, but it gives you some idea of what can be done. This may also give you some idea that this is perhaps not the easiest job for a beginner. If you want more explanation on any of these methods, I will be happy to provide more detail.
