Colourful moon

[Peter Ward]

Still sitting under the clouds in Sydney and still going over old data...:rolleyes:

Colourful moon rocks are nothing new, but the treatment here maybe just a little different.

Hi Peter - that is cool!
I have seen many of these images and I believe saturation (or some other process tweak) reveals soil composition. Do you know why this is the case how it works?

[Peter Ward]

APOD had a good write up about the colours here

Very nice result Peter, certainly provides a different perspective of Luna.

Looks good Peter.
The Moon looks good in full saturation.

APOD sucks and they are hypocrites!

I sent them my high res image of the Moon in colour and I received a reply back "we will not publish images of the Moon in Color as the Moon is certainly not those actual colors, and it would be false information".

I emailed them back with a link to an APOD they did only 6 months earlier of the Moon in color and asked them "what is this if you won't publish the Moon in Colour?", but they did not reply!

This is mine that I sent them:

[Peter Ward]

Thanks Ken , but there is no consipracy here. The devil is in the detail...I suspect they were simply trying to give you a heads-up.

[ballaratdragons]

Heads up to what?
They have published several images of the Moon in colour over the years, but told me that they refuse to do it. :screwy:
The email was actually quite lengthy and went into saying things like how they won't publish images that do not appear as the eye sees them.
What a load of bunkem!
I have no time for APOD.

I realise they get hundreds, possibly thousands of images a day with the authors wanting theirs to be picked as the APOD, but to answer back a lie is ridiculous.
They could simply say "your image isn't suitable for todays APOD, or not even reply at all (I didn't even expect a reply, or to be chosen), but to spin hypocritical lies is what bugged me.

Never mind, it was years ago.

Ishihara test?

[ballaratdragons]

I am not colour blind!

[Peter Ward]

Lord knows, Iv'e been known to call a spade a shovel.

The colour in the image you linked to was not accurate.

Matters not to me, but, did you not see that?

[ballaratdragons]

Well why didn't you just say that instead of snide little remarks, re; 'heads up', 'Ishihara test'.

Besides, the colours in my image are accurate according to the mineral deposits.

[Peter Ward]

I was not trying to be snide.

Both the guys at NASA/APOD and myself were simply trying to point out: the colours in your lunar image are , to be blunt: *not* the same as everyone else's data.

I was wondering why you couldn't see that.

Colour vision is not a given.

Some individuals do not preceive subtle colour differences...hence my reference to the test.

Why do you say the colours in your rendition are accurate?

[ballaratdragons]

They are accurate to the website I used to identify the minerals. Maybe the website was wrong :shrug:

At the time I just googled 'Identifying colors on the Moon' and I used the 1st website listed.

But that wasn't my point. My point was that APOD claimed they don't show images of the colored Moon, but they do.

Looks like a good image Peter. Can you just run through how you get the colour saturation like this. I take it you use a mask and then saturate that mask. Then I am thinking you would blend it with an overlay or something like that???

[Peter Ward]

Hello Paul,

Start with a colour image of the moon.

I have found while you can get better saturation with a mono camera and RGB filters, you also get registration artifacts due the seeing shifting parts of the image in different directions with each exposure...hence a single shot colour camera is the way to go.

The adjustment is easy in Photoshop:
Image>adjustment>hue/saturation

While you can drag the slider all the way across, colour noise becomes quite objectionable. Better to take several iterations with say 30% saturation added each time.

Cool
That's a nice little process I'll have to try sometime
produces great results

Thanks Peter, appreciated.

It should be Yellow, everyone knows the moon is made of cheese !!

[Peter Ward]

Ah, I believe Wallace and Gromit only found limited veins of Wensleydale at ther landing site (Mare Serenitatis) . Blue cheese is clearly more abundant on the Sea of Tranquility...and is confirmed in my roll-over data.

Sorry I just had to try and dampen the aggression levels in this thread
