Quote:You will find your basic adjustments in the "Image" menu, from here head to "Adjustments". There you will find Levels, Curves, Selective Colour, Channel mixer etcetc. I would say get familier with these first before getting into layers, masks and filters. My personal favorite is the "Selective Colour". It allows you to select specific colours and edit them without effect any other colours in the image.For noise reduction and sharpening, you'll find these under the "Filter" menu."Filter" - "Noise" - "Reduce noise""Filter" - "Sharpen" - "Unsharp Mask" (for the unsharp mask settings, try to keep the 2 slider values the same, so 20 for the top slider and 20 for the bottom. 30,30. 40,40 etcetc.)For me personally i save my images from DSS as a 16bit .TIFF, when you open it in photoshop it may ask you if you want to apply a colour workspace, i always click yes and select the colour profile i am using on my monitor (usually RGB 1998). If you have a 36bit image you will not be able to apply any changes (levels, curves etc), to change the image to a 16bit or greyscale, you would go to "Image" then "Mode" and then select your choice from that menu.I have never used Image Plus so i cant help with the transition but ive been using photoshop for almost 10years and will be more than happy to answer any questions you have about it. (keep in mind i use an older version so some menu items MAY have been moved to different locations)
Quote:Here is a current list of ImagesPlus 5 tutorials for using filters with layers, blend mode, opacity, and maskshttp://www.mlunsold.com/ILProcessing.htmlIf someone comes up with a technique not covered then I will be happy to add it to the tutorial page. New tutorials are added on a regular basis.
Quote:Looks like a good start Mike.
The background is a little too dark and looks clipped so your not showing all of the detail. Could you setup for download the stacked FITS from IP with no further processing. I will make a detailed step by step for enhancement using IP 5.0

Quote:There's a definite "art" to using Levels and Curves
Quote:Thanks for elaborating Scott; great guidance I have been looking for.
Quote:Few questions:•If I do 'DDP Stretch' in IP first, is it still ok to do Levels & Curves in PS afterwards?
Quote:•Is it ok to do 'Std. Smoothing & Noise Reduction…' after doing 'DDP Stretch' in IP?
Quote:•Is it ok to do 'Filter-Noise-Reduce Noise...' in PS after doing 'Std. Smoothing & Noise Reduction…' in IP?
Quote:•Is sharpening astro images is a good strategy, generally speaking?
Quote:•If yes, where does 'Sharpening and Texture Enhancement' in IP fall in relation to 'Filter-Sharpen-Sharpen' in PS? Do both complement each other? If yes, what's the preference order? If not, which one is preferred?
Quote:I think you get the idea; I am trying to figure out how to get best of of both, IP and PS, and find out correct order/sequence of processing.
Quote:Quote:Few questions:•If I do 'DDP Stretch' in IP first, is it still ok to do Levels & Curves in PS afterwards?Yes. I always do additional stretching beyond an initial DDP stretch. The DDP stretch is excellent for stretching across the entire image and the entire tonal range, but Levels and Curves allows you to target ranges as well as stretch more aggressively.
Quote:Quote:•Is it ok to do 'Std. Smoothing & Noise Reduction…' after doing 'DDP Stretch' in IP?Definitely.Quote:•Is it ok to do 'Filter-Noise-Reduce Noise...' in PS after doing 'Std. Smoothing & Noise Reduction…' in IP?Yes, but... You don't want to do too much noise reduction. If you completely eliminate noise, the image tends to look plastic and fake. My method for noise reduction is that I usually use Carboni's Deep Space Noise Reduction (you definitely should pop for Carboni's actions - best $22 you'll ever spend - see http://www.prodigitalsoftware.com/Astronomy_Tools_For_Full_Version.html). I usually back off the opacity of that layer to around 50%, because it tends to make the image a little bit soft. I then save the image as a tiff file (you'll have to uncheck layers and alpha channels in order for IP to read it). I take that tiff file into IP, and then do standard smoothing and NR. Resave the file, open it in Photoshop, and then select all, copy it to the clipboard and then paste it as a layer to the original file. I typically back off that layer a little bit to make sure I'm leaving a little noise, but that's a season to taste sorta thing.I think you'll find that if you only use IP's smoothing and noise reduction (and learn to use it well), its probably the only NR you'll need. Its certainly plenty enough to start with.

Quote:Mike, couple of questions. I was able to follow your process to the letter, except for following:1. For some reason, settings in 'Multi Point Planar Flatten Background' remain greyed out; how can I fix that?Edit: Disregard...I was able to fix this; had to click on the image to enable options.2. I see you did 'Hue-Saturation-Luminance' but didn't include a screen shot; nothing major, just wanted to see what you did there?3. How did you enable 'Mask Surface' display?4. How did you generate luminance and inverse luminance masks; and how did you apply them? (I did look at your 'Sharpen Midtones & Highlights using a Custom Luminance Mask' tutorial, but couldn't follow along or understand the flow; plus it creates a mask from a JPG, which is bit confusing to me) Sorry, I am lost on masks stuff if you can help using this example.
Quote:Following is my understanding of your work-flow if you can confirm (for this particular example, I understand...):Note: (Brackets show the menu locations of various items in ImagesPlus 5.0); thought it may help folks locate things.•Digital Development (Stretch-Digital Development...)•Multi Point Planar Flatten Background (Special Functions-Multi Point Flatten Background-Planar...)•Multiresolution Smooth-Sharpen (Smooth Sharpen-Multiresolution Smooth/Sharpen...)•Scale (Geometric-Transforms...-Scale)•Adaptive Richardson-Lucy (Smooth Sharpen-Adaptive Richardson – Lucy Restoration...)•Smoothing (Smooth Sharpen-Standard Smoothing and Noise Reduction...)•Micro Curves (Stretch-Micro Curves...)•Star Size (Special Function-Star Size and Halo Reduction...)
Quote:I will make detailed instructions for each of the above questions except step2. Once these few steps are learned they are always used to assign masks to filters applied to images.

Quote:Mike take a look at this tutorial which shows how to create a custom luminance mask in step 1 and then use it with sharpening filter in step 2
Quote:What you need Mike is a Cookbook
Quote:Smoothing in step 3 and sharpening in step 5 are mild and you do lose a lot with a screen shot. If you use the steps with your image you will notice a difference.
Quote:In a day or two I will post a cookbook for creating many different kinds of masks and for assigning the masks to filters in Process History layers and also Combine Image & Mosaic layers.Mike
Quote:After you go back and apply digital development correctly you will have a much different image.
