Photoshop, when quality matters you can count on us.
I can remove unwanted people and objects from a photo, insert someone or something into a photo, repair over- or under-exposed photos, convert coloured photos to black and white (and vice versa), or do something as basic as removing red eye from photos I can also do colour correction, background change, contrast adjustment, and size enlargement. I can as well remove imperfections, change colour of eyes.
Fast and reliable.
