In v2, the Enhance->Adjust Brightness/Contrast->Brightness/Contrast tool actually made an image lighter or darker.
In v9 & 2018, the same tool seems to only change the HUE of some colors while doing little to change the actual brightness/contrast of the entire image. Same goes for the Lighting Levels tool.
To actually lighten or darken an image I have to apply a translucent layer to cover the main layers.
Once again I'm confused! Is this intended or a BUG?!
EDIT: Intended. Circa CS3/PSE6 |

reshacker -
To the best of my knowledge, there is no brightness/contrast filter in PSE, and never has been. Are talking about an adjustment layer?

In recent versions of PSE there are the Brightness/Contrast commands, accessed via Enhance | Adjust Lighting | Brightness/Contrast... or by creating a Brightness/Contrast... adjustment layer. I think this is what is being referenced.
I feel pretty confident that these have not changed in any meaningful way across all versions of PSE. If you are not seeing a definite change in brightness, I wonder if one or more of your layers are using a blend mode other than Normal.

Just a little clarification . . .
The Enhance>Adjust Lighting>Brightness/Contrast command is not a feature of recent versions of Elements; neither is the Brightness/Contrast adjustment layer. Both have been available since at least PSE 7 (the earliest version I have). |

Yes, the tool itself has been around since at least v2 and looks the same in all versions.
In v2 go to menu bar Enhance->Adjust Brightness/Contrast->Brightness/Contrast.
In 2018 go to menu bar Enhance->Adjust Lighting->Brightness/Contrast.
I've edited the OP to reflect this.
Here are two copies of the same file adjusted to the same values of Brightness -100 & Contrast -50 in each PSE version:
Image edited in v2:
Same image edited in v2018:
 <- How in the world can this be a result of adjusting brightness and contrast?
Same tool. Same adjustments. Different outcome.
To make the 2nd image look like the 1st one in v2018 I have to add a 2nd layer, fill the entire layer with black, and reduce transparency to 75%.
BTW, this is one of the many reasons I said 2018 seems buggy.
@ Tpgettys: I almost never change the blend mode. This file is Normal.

What's more strange is with the "Levels" tool. When I select green (from rgb) and darken that value, the darker green turns purple and the lighter green remains unchanged.

Hi reshaker,
I have used only PSE 7, 10 and currently 14 and the Levels and Brightness/Contrast adjustment layers have and do work as they should and consistently over those 3 versions.
If you haven't already done so, perhaps have a look at the histogram of the image in each of your PSE 2 and 2018. Since you are getting different outcomes the difference in the histograms might help explain what is going on.

If "darken that value" means moving the left slider (black) of the 3 sliders to the right, then you are effectively clipping more of the green RGB values (setting it to 0) the further you move the slider to the right. This means that for each pixel there is now a much higher proportion of red and blue colour, resulting in a purplish colour. |

THX bailey. Histograms appear identical tho v2 only has Luminosity, red, green, blue vs v2018 which has that plus RGB and Colors.

I would have to have the actual original image file so I could see the actual rgb values and how they change with the adjustments. Otherwise I would be guessing to a large extent. |

So why does the lighter green (in the pics above) remain unchanged? Hi reshacker,
I did some testing selecting the Green channel and using Enhance>Adjust Lighting>Levels. I tested this in ALL the versions of Elements I have -- 7, 10, 11, 12, 13, 14, 15, and 2018. I can confirm that:
- There is no need to check the Histogram. - There is no need to look into the amount of Red + Blue = Purple.
The explanation seems to be a simple one. What you describe -- "the darker green turns purple and the lighter green remains unchanged" -- will happen when the adjustment is being made using the Input Levels sliders. (It makes no difference which PSE version you are using.)
Try bringing the Output Levels sliders into the mix. I believe you will get the results you want.
NOTE: My screen shot is from PSE 2018.

Without having the original images, I will take one stab in the dark. The lighter green pixels will most probably have Green values (RGB) close to 255 and low R and B values. So unless you move the black Levels slider for the G channel to very close to 255 on the right, you won't be actually clipping any G values and so you won't see any significant change to the lighter greens. The darker green pixels will have low G values and so they will get clipped much sooner as you move the black slider to the right. Hence the larger proportion of red and blue colour in the darker green pixels resulting in the purplish colour. I hope this helps, but from hereon I would need the actual original image and/or a screen shot of the histograms you are seeing in your PSE. |

hi Sepiana, That is exactly what I have been saying about moving the black slider of the 3 to the right. But the reason behind the purplish pixels is the higher proportion of red and blue after the green has been clipped. It's important to understand what the effect of clipping the various channels has on the image and why it is so. Output Levels settings set the final black and white points for the image. It may or may not give the results the OP is looking for. The op asked "So why does the lighter green (in the pics above) remain unchanged?" Maybe I am misunderstanding something but I don't see how your solution answers the question. |

reshacker,
I had all but forgotten this . . .
The Adobe Design Team did make some changes in Brightness/Contrast. If I remember it correctly, this happened before PSE 7. But, from the information I have, they were made with the purpose of improving the performance of this tool. In short, this tool is much improved from earlier versions.
