This probably happens to my photos hundreds of times every day; however, I had seldom really noticed just how dramatic things could be.
I had been looking and finally found a photo I had been searching for from 1972 and downloaded the jpeg.
It was flat and hazy and dull and the highlights were almost blown.
I ran it through DxO Photolab II Elite, using my usual(always) recipe and then pulled back the highlights and lightened the shadows, saving as a jpeg.
Side-by-side, both carrying the exact same metadata, the faded bleached-out original is 608-KB
The much improved DxO version is at an almost eight-times increase of 4,356-KB
Just worrying this around in my mind before I clicked Create Thread, I think I will use FastStone to take a screenshot of the improved version and see just how many KB that will have.

The much improved DxO version is at an almost eight-times increase of 4,356-KB I do not own or know about DxO. Is the new image still a jpeg? (or PNG? PSD? Or? ) Was the pixel size increased? |

My screenshot comparison idea went out the window as the dimensions of this particular photo exceed the available screen size. |

Is DxO saving it differently (Progressive vs Optimized)?

(Progressive vs Optimized)
After noticing this huge growth, I am going to pay closer attention to see if it is only the produce of DxO, or just the way it is with all manipulated/improved photos regardless of program. |

I've no idea how DxO behaves, but if you do a Save As in Photoshop Elements and select JPG, you have options for "Baseline (Standard)", "Baseline Optimized", and "Progressive". You can go to the link below to get a more detailed explanation, but there is a difference in file size from what I can read. It probably doesn't explain the difference you are seeing, but it is one thing to check. www.thewebmaster.com/progressive-jpegs/ |

Regardless of the program, I always save at the highest quality possible; other that save quality, most of my programs don't offer any other options.
The next time I have the Save box open in DxO, I will investigate to see if there are any options other than quality. |
