Hi. I am new to Paint.net and to all other photo manipulation software, for that matter, so bear with me. I have a series of black and white photos which I have taken over the years. I am now going to have them in a gallery and they all need to be approximately the same shade of gray. That is to say, because the photos have been taken with different film stocks and under different lighting, they all look just a bit different. Is there any way to find out the exact saturation point for one photo, and then copy it to all the other photos? I have tried looking under "Levels," but it doesn't seem to give me the RGB reading for a photo, just the histogram, but no numbers associated with it. This may be a basic question, but please help.

Unfortunetly there is no basic way that has been released (*Cough* Pyrochild *Cough*). At the moment your best bet is to play around with the 'Key' Levels and try to match but this could be difficult and tedious. I am sorry!

Honestly I think that the plugin Color Balance has basically the same effect except that it doesnt do key. Does anyone else agree?

I dont, by any means. Color Balance does not give nearly as much flexibility over the color you choose to alter and by how much you to choose to alter it by. If you read through this tutorial, you will find that Levels can go above and beyond what Color Balance can currently accomplish.

Edit: As well, I want to make a public statement regarding this tutorial: it is no longer hosted on site :shock: I have reformated the tutorial for various reasons. For more information as to why, please reread the first post.

Hi mike, thanks for the great, great piece of software.
Unfortunately, I can't open the pdf document with SumatraPDF (vers. 8.0b), is it possible to make it available for people using this program as well? I would really appreciate it!

Hey Mike, sorry, my bad- I opened my big mouth, before checking what exactly I'd downloaded and the file was incomplete for some reason. A case of too much faith in my internet connection and perhaps not enough in SumatraPDF (although totally unwarrented.) Thanks again for the great work.

Alright, I will look into it some more. I think it may be my PDF software, or perhaps the version number of the PDF filetype I am using.

Mike just a little more info, just tried to d/l it again and filesize when finished shows 435KB as opposed to previous 217KB. Still can't read it though.


UPDATE


Managed to get and view the complete file at last using Firefox's DownThemAll d/l manager. In between I tried a couple of time more using Firefox's built in manager and still failed although the file size kept getting bigger each time.

Really Weird :roll:

Then yes, it is a server issue :(

I believe that the file is to large to be hosted here, so I will change the host over to DeviantArt. Thanks for the information! I will have it updated by tommorow. If you want it now, hit me up with a PM with your email address and I will send it to you.

Ummmmm

I must be missing something;

Point 6............

.........Be sure that all check boxes
are checked because we are going to
alter the Key color channel. Use the
following settings to alter the amount of
white versus black to 'burn' the image.

Other Uses for Levels
Levels is good for multiple things. A good use is using.................


There aren't any levels listed
and I can't read them off the image cos on my crude 19" Dell monitor,
dey iz all fuzzy like, man!

So that bit lost me

What are those there settings ?
Please? :mrgreen:
