Recently I went on an excursion with a friend of mine at Mount Teide (Tenerife, Canary Islands) and we took some pictures.
Now I was watching them and I decided to do a quick photo retouching, combining two of the pictures we took.
To do that I used Adobe Photoshop.
As you can see, I added a picture on my friend’s screen. This is not really difficult: I added the picture using the vanishing point solution to keep the perspective (Filter – Vanishing Point), but I think using the transform menu (Edit – Transform – Perspective) would do the job as well.
Then adding a mask I brushed away the parts of the picture that were covered by the hand. With a bit of color correction to give some consistency you could consider the job done, but the really tricky part in this work is giving some authentic reflections on the screen.
As you can see in the first picture, there is too much light to see what the screen shows, so we see just a black screen with the reflection of her hand and the landscape. Although showing clearly her picture in the screen is bound for this effect, it should be a mistake not to add some reflections. How to do it? Very easy.
I copied the original image on a new layer and I put it on the top, then I lowered its opacity to a 30%. The majority of the picture has not been affected by it, the only change has been on the screen that I had previously modified, so it kept the original reflection!
