In the graduation thesis, I presented influence of computer-processed photos on their communicativeness. In the theoretical part, I wrote about the digital photography, processing of a digital photography, and editing programs. In the graduation thesis, good sides of processing are presented, and they are supported by examples from Internet. I also mentioned communicativeness itself. I presented what and how it affects communicativeness. I also presented the impact of the processed photos on emotions and supported that by using the Noldus Face Reader program. In the practical part, I shifted all the theory into the implementation. I presented the photography processing from the capture itself to the final processed photography. Processing is presented in Adobe Photoshop. I checked the final response to the processed photos and their communicativeness in an experiment using the Noldus Face Reader program. In the experiment, I used two examples. Each example consisted of three photos. Photos are copyrighted. All of the participants also took part in the survey, which represents the second part of the experiment and according to which I checked their opinion regarding the photos. At the end of the thesis, I presented all of the data obtained in the program for emotions detections as well as survey. Based on the obtained data, I could link general statements on communicativeness with the actual ones.
