In the continuing trend of collaborative processing tips and techniques, open sharing of information and ideas, I've uploaded the raw stacked images from my excellent Jupiter session on the 26th May.
The files are "raw stacked". That means, I've ran them through registax to align and stack the raw frames, but have not done any wavelet or other processing on them. They have had mild noise reduction applied in photoshop (part of my usual processing routine).
Each file is a 1.2meg TIF file. Right-click on the link and click "save target as" to save the file.
As a suggestion for the less initiated, open each channel one at a time in Registax, and it will take you straight to the wavelets page where you can start the processing.
Use AstraImage, Photoshop or similar tools to combine the image back into an RGB image.
An (un-inforced) requirement is that you post your processing steps when you post your version of the image. This will help everyone (myself included) learn from your method of processing and be able to compare the results.
Have fun, and I look forward to seeing the results!
OK, I got it now. They load into CS OK, but they are already RGBs, which causes a fault loading into registax. I converted them to grey scale in CS and now they load OK in Registax.
CS doesnt have wavelet processing, so I was keen to try that 1st.
Ok here is my attempt, I dident know really what to do and took me a while to combine then in Astaimage. I had to convert them to gray scale first? is this right? I thought RGB images were already in gray scale. tried the LC then combined them the put it through focus Magic to sharpen it up a bit. Then into photoshop played with the color and levels, then save to the web. I dont like the banding I got around Jupiter and I couldn't get the color right for me. Need heaps more practice.
Edit:- did two more tried to get it darker and more detail
Put it in photoshop, paste into RGB channels. Messed around with contrast, sharpening, auto levels, auto color, levels, etc. Desaturated the blues that ended up around the edges.
Thanks for having a go, Joe and Ingo. I'm surprised others haven had a shot at it.
While the captures are in mono, at some stage during my pre-processing (ppmcentre etc) they end up as RGB bitmaps even though they're single channel. So it's normal (for me) to have to convert them to greyscale before combining them.
I didn't have any trouble opening them directly in Registax 4 though?
Joe - your first 2 look good in terms of data and sharpness, but they're too pink/red. Try adding more green and blue in the levels. The last 2 are good for colour, but the details are kind of blurry and not sharp. Great attempts though, well done.
Ingo - yours looks good, nice colour but could probably do with a bit more sharpening. Nice job for a non-planetary guy.
I hope to see some others, and I hope this project has helped anyway, and I'm happy to do the same again in future when I've got good data to share.
By way of comparison, here is my version of processing on the same data, done back at the time of capture.
Of course, processing is a very subjective thing and what looks good to one person might look oversharpened, or the wrong colour, or whatever, to someone else.
very nice image Mike. I think its a good idea will help build up our skills, and shows how much different one image can be processed with the same data.
1. Convert each image to greyscale in PS CS3 and save.
2. Open each image in Registax V4, and apply 'Dennis wavelets" (1=20.1, 2=10.5, gaussian linear) and save.
3. Load each image into CS PS3 again and combine into RGB.
4. Levels (top slider each channel down to 192).
5. Curves (I chose standard increase contrast curve and then lifted the dark end of the curve a bit).
6. Selective colour: Cyan -60, Magenta +40, Yellow -32, Black 0.
7. Save for the web.
The wavelets might be a bit harsh for this image - it looks a little grainy to me when combined to RGB.
1.Converted original images to greyscale, doubled them in size and saved them in PS CS3.
2. In Registax 4 I Stretched intensity levels, applied heavy wavelets (22.1, 11.2, 10.5, 10.5, 21.2, 25.3 gaussian linear), gamma 0.7, histo stretch top slider to 175.
3. Back in PS CS3 I combined images into RGB.
4. Adjusted levels (R 219, G 209, B 212)
5. Curves (dragged down a bit like reducing gamma to increase contrast in highlights)
6 Saved for web reducing size back to original.
Make your own Jupiter from my data
Just goes to show... I'm not getting the sort of detail out of that data that you are Mike! Care to share details?
