I have aerial photographs taken by an Unmanned Aerial Vehicle (UAV). I want to look into details to find my target by zooming on the TIff images. Which open-source tool would be effective for the processing of aerial images? Thank you.
For your purpose, you can use QGIS which have a lot of tools and plugins for processing of aerial images . It also integrate other great software like SAGA od GRASS which all give you acces to a lot of image processing tools. You can also add another great free image processing softwrae named Orfeotoolbox
All these sofwrae have a lot of documenation and tutorials on internet
Md. Alauddin SAGA GIS would be wiser choice for intended purpose you have mentioned. It is portable GUI-driven software with intuitive sleek design able to perform variety of image processing tasks. Notably, it requires little disk space to run in contrast to QGIS.
If you only want to see the images, any of the softwares suggested before can work. But I think the use and manangement of aerial photos in general requires specific knowledge and tools. Could be not only a question of zoom in or zoom out, there are too many problems reltated to the capture, correction, management, of that kind of data and the level of tools you will need depends of the complexity of your work.
I found this paper (Mohamed also suggest it before), looks complete and I think could be give you a good landscape of how to work with aerial photos and what kind of tools you will need.

Hello Mohammad Alauddin, If in addition you would like to create a 3D digital model, I recommend to start with Open-Drone-Map, based in SfM: https://www.opendronemap.org/
