Gamma Correction

The other day I learned a new word… Gamma!

After spending a very frustrating afternoon attempting to print a picture which looked nothing like the picture on my monitor I learned what gamma correction is. Now I could go into an in depth explanation of what this word gamma means, but I don’t feel I truly understand what it means to explain it properly.  What I can tell you is how I fixed it. If you would like a more technical report you might want to check out the Wiki – Gamma Corrections

The picture above  is the same exact picture displayed with different gamma settings. The picture on the right is what my monitor was set at so when I edited the picture I ended up with a blue and orange picture which is what I wanted.  When I printed the picture it looked like the one on the left with a very dark dark background.

To change the  gamma settings: Right click on the monitor – go to properties – settings – advanced – Click on your Graphic Adapter mine is a GeForce FX 5200 – Click on the Display Control Panel to see your settings . I lowered my gamma to 0%.  I then edited the picture again since the color was off and hit print with my fingers crossed I waited… and it worked!

The harsh news was everything I have been editing is edited incorrect. I looked back at my recently edited photos and realized most were a bit dark. Apparently I haven’t printed anything in awhile so I am still unsure how or why it changed.  I can keep guessing on that one, but the problem seems to be fixed!   Today I had our Christmas cards printed locally again I was worried about the outcome.  My monitor and printer seem to be working together, but what about outside my little work area. When I opened the box I was relieved to see exactly what I had hoped to see… phew!

Now you are probably wondering where did I get this beautiful scarf to photograph! I was surprised by my ever so talented friend Erika on my birthday! A beautiful lady who continuously impresses me with her kindness and creativity! You can take a look at some of her knitting projects on her website mamalovesknitting.com.

  2. Hi,

    me again… 😉

    I searched for some places on the net that might be useful.

    http://www.wikihow.com/Calibrate-Your-Monitor

    So here’s a subject I’m not too familiar with. I ‘calibrate’ comparing ‘what I see’ with ‘what I get’ on a regular basis. Furthermore I always check settings when I get updates of the (display)drivers or Windows itself. Most photographers I know use a ‘Spider’. That a great device which ‘looks’ at your screen and adjust the soft settings automatically to the optimum. The hard settings (the ones on the monitor itself) are coached by the Spider-software (which is my understanding, I have no experience to verify that).

    Anyway, good to hear (and see) you’re taking huge steps in improving and understanding the fine art of photography! Keep going! 😉

    greetings, Marcel

    p.s. I don’t knit… LOL

  3. As always you’re so sweet! Thanks for the additional information and links on gamma correction. Gamma correction is a huge new avenue to understand! There is always something new to learn!

    The Spider sounds interesting! I think they must make software for everything if you look for it! That is crazy that it automatically adjusts for you!

    Take care! Amy
