Let’s talk about photo retouch how you improve the final output. When we take photos of buildings, most time buildings are huge and the person who is taking photos is on the ground looking up trying to put the entire building in the frame. That creates an interesting perspective view something like this sketch.
Depending on what you are trying to tell through your photos, it could be ok as it is shot.
However, if you want to fix the perspective, you can do that in Lightroom.
In your camera, you can select if you want raw or jpeg. As you know, jpeg is compressed format. You don’t want to compress until the last output.
Always take photos in raw and bring it into Lightroom. Go through the menu to which one works best for your photos. You can also do it manually.
These are some before and after photos for these examples.
