Prologue#
I have been playing photography for a while now, and recently I feel like I have reached a bottleneck in my skills.
Most of my previous photos were taken in special times and special scenes, and most of them cannot be reproduced. They are like beautiful misunderstandings. My photography skills are completely uncontrollable, sometimes good and sometimes bad, with slow progress.
Today, our family officially starts learning post-processing of photography, referring to books such as "Digital Photography Post-Processing Complete Guide" by Chen Jianqiang. We will learn tools like PhotoShop, GIMP, AIGC (Chanting Secret Technique, ControlNet) to master the magic of images!
Thanks to Xlog for providing IPFS storage, which eliminates my worries about image hosting and storage. So most of the images below are JPEG, Tiff, and other high-definition large-size images.
[Modified on April 3, 2023], the images in the xlog export format are IPFS links, which are difficult to transfer. Starting from April 3, this site will use image hosting to store images.
Spot Removal#
Off-topic#
This requirement may be about fixing blemishes on the skin, flaws in pictures, small-scale image cropping, etc. for ordinary people, and may not be used frequently. But for me, it is a hard requirement!
Due to my poor maintenance and lack of habit of cleaning the lens, after taking photos, I just put the camera in my pocket. My poor (first/last/only) compact camera, SONY DSC-WX350, has developed sensor dust—irremovable spots on the lens. It's as annoying as the countdown in Wang Miao's eyes in "The Three-Body Problem". It's not noticeable when encountering dark scenes because the spots blend in with the scene. But once I encounter a light-colored scene, they become glaringly obvious, making me grind my teeth in frustration.
Below are its "glaring" appearances (pay attention to the right side and bottom left corner of the images):
However, in dark scenes, it's much better:
Without further ado, if it weren't for its flaw, I wouldn't have written this article. To some extent, I have to thank these little incidents for giving me more opportunities to learn.
Today's Homework#
Today, I mainly learned these tools:
Spot Removal on Clean Background#
Both the Spot Healing Brush Tool and the Healing Brush Tool can easily remove spots.
Before the repair:
The basic steps are not worth recording, as it is a foolproof operation.
After the repair:
Complex Repair#
Here, I will use the little horse I encountered last week as the material (I randomly adjusted the colors with LightRoom, which made the horse look unreal 🫣).
- Patch Tool: For large-scale modifications (it's even easier with Content-Aware Patch enabled).
-
Content-Aware Move Tool: For large areas of spots or texture repair (e.g., repairing the white garbage bag on the right side of the horse's leg).
-
Clone Stamp Tool: For repairing edges (e.g., the boundary between the horse's leg and tail).
