dx, I fixed your reply 100.

To create and save macros that are posted here try the following:

Select and copy the macro code between the "cut lines" in a comment.

click on the imagej command Plugins / Macros / Record...

Paste the code into the imagej Recorder window and then click the "Create" button.

That will create a macro file with what was in the Recorder window and open the Macro.txt window.

Click on the Macro.txt window File / Save menu item. That should take you to a dialog box with the macros directory as the default. You don't have to put it here - it's just a handy convention.

Give the macro file a name you can remember and click the Save button.

Congratulations! You have just "imported" your first macro!

NOW to use the macro:

If you are going to use the macro more than once during a session, select the menu item Plugins / Macros / Install...

navigate to the macro you want to install and then click open.

NOW when you select the menu item Plugins / Macros you will see the installed macro at the bottom of the menu.

To run it, just click on it - once you have loaded the files the macro will use!

I would suggest using the macro in reply 20 for testing.

I call it 16Stack because it will take an arbitrary number of files with 8 bit formats - including RGB -- and converts them to 16 bit format and stack them. Very handy.

Let me know how it goes.

Done...the Macro as suggested in your 101...worked perfectly. MacroMars100.ijm is the name I gave it and it showed up in the Plugins>Macro at the bottom-thanks. I don't know what it says in your 20 but it copied and pasted without a hitch.

Now to give it a try out.

Your second last sentence says 'this macro will input any number of image files in either 8-bit and/or RBG and converts them into 16-bit format and stack them'.

So I still have to go through the Stacks>Z-Project with this stack? or go directly to Color>Merge?

if three slices are in a stack then the menu item Image / Color / Stack to RGB will create an RGB image with

( R, G, B ) = ( Stack[1], Stack[2], Stack[3] )

Prepared 3 separate stacks RGB with 3 slices the same in each stack all made with your macro. No problem-all 3 stacks in B/W.

Your 103 says RGB image will result from the combining of the 3 stacks...they did and it gave a heavy duty 4MB color image. It was markedly clearer and cleaner than the image I placed in my 82 [bottom image] since I already had images worked on so it was easiest to open and see the difference.

That image I did not upload to flickr, I thought it was too large to present here so I reduced the size and obviously the clarity went with it. I did save them to my comp as image comparisons.

Is this what your formula is supposed to do-increase the refinement of the objects in the image?

Thank you for this intriguing macro advancement in image presentation. Its different to be sure.

Really played with these 2 images only [M1] over the past few days trying to make a merge and I did not think that a color image would occur. But I got it to work, finally...and thanks for having the MRB fixed.

You are very kind in your statements of 107, but if it wasn't for hortonhearawho I'd remain struggling to present any image at all using imageJ. Its with his kind graces and unselfish guidance that has opened my mind to merge the thousands of accessible Mars images into a complete color rendering I am used to seeing from his untiring work on the subject.

As an award winning designer in Architecture,Graphics and Interior presentations, I assure you I have learned a different technique from horton which I am greatly happy to use in my own work.

Trust others on the MRB are focusing in on horton's lessons in this thread as I have.

If they have, please present your work here...horton can review them for accomplishment. You won't regret it.

I like your colors, dx. They look more "live action" to me, and less "cartoonish" than the monochrome red-orange renderings that are popular in some quarters.

With your colors, I can take in the scene better and imagine I am there.

Thank you for your favorable comments. I'm having one good time with imageJ...and I've just started. There is no PSP in the images produced-wanted to stay clean without additives from another program. But, if I examine a certain image that I feel can have a better look to it, then I'll post it here for all to see.

Imagine how hortonheardawho feels and he has been using it from the start here on the MRB.

I salute him for sharing his thoughts and his willingness to teach others.

Choosing some old Spirit pics to work with especially distance images without loosing too much data in the foreground.

Spirit sol 241 montage of processing steps:

see the Flickr comments for processing notes.

dx, you should use the original data from Analyst's Notebook for any images less than sol 2700.

Of course, this is all art, so my vision may not be your vision.

Hi h>>>

Thank you for your colorful montage. I wanted to reduce the blue sky as I had done and you have done in your 2x2. Our L257 was exactly the same. To me the background hills were the most impressive and influential part of the pic and to improve the image color depth of those hills the foreground data was compromised a bit. But, you already knew that!

Greatful you posted your pics of the same images, thanks...I needed that and wanted to see your results to know where I am in your thinking regarding presentation.

Many thanks for your work here on the MRB and with me.

BTW>>>did you use the Analyst's Notebook for your images in 113?...and BTW why is that one has to use images less than Sol 2700? Is it important? This is new to me.

I read your note on flickr with respect to your image merge. Thanks again.

dx, the original data is only publicly available before sol 2700. Every six months or so another batch of original data is released.

As I suggested earlier, the imagej brightness / contrast command is one you should get to know well.

Spirit Sol 741 Rock

First image tried as colored L257 image merge. Image best from imageJ - struggled to keep the colors not so BLUE!

Second image brought needed help to the first. [Friday afternoon martinis going down very well]

h>>>Going to upload your huge first post macro L234567x2mx-3 over the weekend for some trial excitement. I'll change the smiley into an 8. This means I have to look at quite a few images to find L234567...is this correct?

When Curiosity lands and its colored cameras are returning colored pics of the surrounding area, how will the imageJ program react to the color merges?

I can imagine that we would have a much better foothold on color when images are sent back and have to realign our art work to match!!!

Are you thinking along these lines, for its about 3 months away from those pictures?

dx, Curiosity will be a new challenge for image processing - assuming it makes it to the surface in operational condition.

Firstly, it is not clear there will be anything equivalent to the almost complete JPG camera data in almost real time available to the public - even though the cameras have "built-in" JPG compression capabilities!

Secondly, the science cameras have a Bayer Filter Pattern on top of the 12 bit CCD - and 14 filters in front of the lenses.

So the "original" data will consist of the 1600x1200 array of 12 bit RGGB values. I am sure there will be an imagej plugin to read the original data - even if I have to write it.

The science cameras also have a HD ( 1280x720 ) "movie" mode ( 10 fps ).

And then there is the MAHLI camera. And the Chemcam and the Hazcams and the Navcams and of course all the other science instruments...

I hope it makes it to Mars OK. Until then, I can't allow myself to get too excited.

The MAHLI cam and other cams sure will give us details never ever seen before on Mars. I really really (did I really say really?) really hope it makes it to Mars in ONE piece and in good shape.
