Samsung S23ulta - 原廠相機 10x vs Gcam 10x

前鏡頭自拍調配: 原廠(上) VS AGC8.8_V3(下)

Gcam 調配在沒開美顏前儘量維持原樣, 以自然修飾為主, 差不多可以了, 和 Samsung 原廠相機對比 ... 又要跌破我的眼鏡 ... 真不知道該說啥 ... Samsung ...

(若對你眼睛有傷害,可以跳過 但似乎讓你知道我的年紀了...)

強制放慢快門來換取更高的純淨度......1/24S變成1/7S,這不利於拍攝會動的東西吧.....

當然不利, 這只是 Selfie shot quality 改善比較; 但8成拍攝Selfie shot 很少動作中自拍, 除非你是慢跑者 or ...

Make a Record about chat with Jacob:

I:
I mean for you guys to tune gcam config – At this moment, you feel this config is good. In next time you change another scene to take a shot but you still feel that something still can be improved … It keeps continuously cycling it and it’s endless…
Question: What’s your criteria or specification to keep current config ? Will you change it just for users feedback a tiny defect in the photo when they use your config?

Jacob:
I think the most important thing when developing XML is to have a goal. To decide how you want the photos to come out and make priorities. Creating an XML is about making compromises for the greatest overall results. You might have to sacrifice something, maybe some difficult scene that you shoot very rarely and accept some flaws in order to get the results you want in most of your daily photography. Otherwise it is easy to find an issue and when you try to solve it, you break something more important.
Personally I am not as big “noise hater” as many here. I think it is important that the noise is not distracting. If it is there, it needs to blend nicely into the details and texture of the image. Chroma noise is a big no. That never blends with anything. When I got the 13 Ultra I immediately noticed that the IMX989 1” sensor has a more pleasing noise than the HP2 sensor in S23 Ultra. It looks more like film grain than digital noise. This is more acceptable to me and I can sacrifice some noise reduction for greater detail.
Other than that, my main focus is to capture the light in a realistic way. That is what photography is about for me. I absolutely hate flat images with too much HDR where almost everything looks “equally bright”. I want deep shadows and strong highlights. The best example of a camera with an image style I hate is Pixel 7 Pro (unless the shadows slider is used to reduce shadows brightening). It looks super flat and artificial to my eyes with strong reduction of highlights and too much boosting of light in shadows which also creates ugly HDR shadows/glow around trees and buildings.
The best thing with GCam is that it can be tuned exactly to your own liking because it is very unlikely that any company making phones will share exactly your own image style.

學會Gcam tuning skill,任何你想要的相片風格都可以經由精心的參數調配產生出來,而這也是屬於你自己獨一無二風格的相片,與同樣拿著S23U的大眾拍出統一風格的相片,更顯出你的獨特性!

AGC8.8_V4 昨天已發佈, V3配置檔import雖然可用,但是不知為啥很常 defocus導致拍出相片糊 ~~~ 所以,重新弄了版V4配置檔, 非常快, 因為發覺設置上除了UW需要花點時間調,其他鏡頭不需要做啥, 做完基本設置後試拍, 挺不錯的


3X,肖像模式

花了點時間 Cook 一下 AGC8.8_V4 配置檔, 順便放上 Java V4 的最新測試配置檔,我順便放上我的配置檔 VS Java的配置檔1X拍出相片對比, 就知差異 ~

1.Reference Samples: https://mega.nz/folder/phMzTbLA#ASau8FY2iJUCxDXDcJjVew
2.AGC8.8_V4 檔案下載處與我/Java配置檔下載處: https://mega.nz/folder/J4FBACxS#zXYa1nYTIxBBDug80Oi6yg

註:
1.若你之前V3安裝的 package name 是 samsung, 可以下載 V4 package name 是 aweme 安裝與 V3 並存
2. AGC8.8_V4 老步驟: a).Import noise model; b).load 我的配置檔; 至於 Java配置檔不需要做啥,只需要 load 進他的配置檔即可使用, 因為他選用 AGC8.8_V4內建給S23U用的 Noise Model, 但我不Trust, 所以還是manual 方式 import 我網上提供的 noise model ~

報告!

刪除V3版,裝V4 samsung版之後,怎麼拍都會閃退
刪除V4版,改裝aweme版之後,就完全正常了

在10倍、夜拍上跟原廠相機比起來確實有差距,感覺原廠還有相當大的進步空間,其他模式還沒什麼機會試。
早安

AGC8.8V4 + 我的配置檔

AGC8.8V4+我的測試中配置檔

一直思考之前配置檔 denoise_a/b 應該要往不同方向調整, 若都一致往負的方向調整, denoise 過強失去細節度且相片整體會偏soft... 且放大看表面,會有小小顆粒感, 不喜歡, 順便調整 spatial/luma 增強details.

PS.中壢舊市區市容,真是無言以對... 即將開幕的A22捷運站出口對面那棟古老大樓,真是醜斃了... 且A22旁中壢市去最高建築,外觀不知多久沒洗了...

找到Gcam在拍夜間景物時可以抑制高光讓你可以看見招牌上文字與圖案的調整方法-透過曝光控制來達成 !! 不知道 Google 官方第幾版已改進 Gcam 一直以來的拍照弱項 - 夜拍高光抑制不好

以下是兩組照片 - 第一張是Gcam當下拍攝景物截圖, 而第二張是按下快門拍出的相片... 注意: 我沒有 Retouch 手機螢幕上任何地方去抑制曝光, 直接就是第一張Gcam當下景物直拍 !
