Jupiter - gamma setting results

[davidpretorius]

Hi, last test for a while, but has it opened my eyes to a small change in settings.

I had always set the gamma to 0%, bird mentioned once to have some in to start as you can always take it out, so i always hang around 0-10%, but i must say, there is something compelling about the 25% / 50%. I will study a bit more, but i believe I will capture at least a couple at these higher gammas next session.

Anyone deem one to be the best???

Yeh I always have gamma between 25-50%. It helps to bring out the crepe ring on Saturn, and helps to bring out the edges of Jupiter so there's no scalloping where the darker belts meet black.

Another good test result.

25 does it for me, I usally have it higher myself more like 50%

more time saved for me - thanks DP:)

Dave, I prefer the image with the highest setting as the planet edge detail seems to be much better, although there is a little loss of detail overall. Could you take images at the upper and lower end of the range and stack to get the best of both worlds? :confuse3:

i can only try i spose. the actual terms ie gamma, contrast, brightness still elude me, i sorta know what buttons to press, but when i hear janoskiss talk about colour theory etc, i am quickly lost

I'm finding these days that I have the gamma somewhere between 60% and 80%. This is a total change from last year where the gamma was set always to 45% (limited by the old camera).

Here's a trick - set the gamma low while you're focussing, cause that makes the features easier to see, and then set it high while you capture. Don't worry that the image looks pale and washed out, you are actually capturing and storing *more* colour levels with the higher gamma, so there will be more detail in the final image.

Leaving the gamma on 1.0 is probably not advisable, that seems to be going too far, but try with values between 50% and 75%.

You can always adjust the gamma later on to take it back to the darker image, but when you do this you are losing a good portion of the subtle shades in the image.

thanks bird, i will try this, but lets keep it a secret from iceman, just between you and me it will drive him crazy.

we can pretend it is a complicated fourier transform or something that only works in the act / snake valley / tasmania
