Hi James,
I forgot to say that I sharpened in LR at the preset of 25% and radius one.
I exported to Adobe Elements and reduced noise Strength 80% Preserve Details 80%, reduce colour noise 25%. I have a trial of Topaz denoise but it makes my images soft (it could be my skills) so I'm trying to avoid it.
Then I re-sized to 1200 pixels and used an un-sharp mask of 80%, .3 radius and threshold 1.
I have this pasted in a document on my desktop as a reference on sharpening, to learn by... I copied it from a thread somewhere here.
Many members find they have problems with image quality, there are many things that can cause this, I'll start with the easiest to resolve
If you have uploaded a picture by any of the above methods and are unhappy with the quality when you see it in a post here at CiC, please consider these things:
Ensure you have no browser zoom set - you need to display at standard, or 100%, size.
With both IE and Firefox, the quickest way to do this is to use Ctrl+0 (zero).
Now make sure your screen size is allowing you to see the image fullsize; use F11 key to switch browser to full screen mode, then click the image so it opens in the lytebox, it may now display bigger.If they were not the problem, how did you downsize the image?
The first thing to say is, if you're using Adobe Elements, Photoshop or LightRoom; DO NOT USE: File > Save for Web to perform the resize and jpg save all in one go - it seriously knackers the image quality and removes the camera's EXIF data!
Here is a recommended method:
1) Take your full size post processed image before output/final sharpening and if you haven't already; reduce to 8 bits and Flatten the image.
2) You need to downsize the image;
2a) Select Image > Resize from menu in your image editor
2b) Ensure Constrain Proportions is checked
2c) Use Bicubic as the method (not bicubic sharper)
2d) If necessary, set image size units to pixels (not cm or inches, etc.)
2e) Type into either the width or height box, the dimension in pixels you want the image's longest side to be (this varies depending where the image is to be hosted; 700px if here at CiC in album or as an attachment, but can be larger if TinyPic or third party, e.g. PBase or Flickr, etc.)
2f) Click OK to perform the re-size
3) Now you must re-sharpen the image, here's a recommended method;
3a) Ensure you are viewing the image at 1:1 or 100% in your image editor
3b) Select Image > Enhance > UnSharp Mask
3c) Set an Amount of between 100 and 200%
3d) Set a Radius of 0.3 or 0.4 pixels (no more)
3e) Set a Threshold of 1 to 8 levels, depending if the image noise, if clean (100 - 200 iso) use 1 or 2, if noisy (over 2000 iso) then use a high number.
3f) Click OK to perform the sharpening
4) Now select File > Save As
4a) If necessary, choose jpg
4b) RENAME the file, I suggest with a suffix denoting size; e.g. for landscape, "mypicture_W1000.jpg" or for portrait orientation; "myportrait_H600.jpg" or for square crops; "myportrait_S600.jpg"
Don't close the image in your image editor yet, host it (see earlier posts above), review it online, that way, if necessary, you can undo the sharpen and resize and have a second go, saving and uploading as a different filename, without any further quality loss.
Notes:
For image critique and general postings, to avoid excessive download times and prevent images 'overflowing' people's screens, I would recommend the maximum height of any picture is 800 pixels and the maximum width is no more than 1200 px (where ever hosted), occasionally these guidelines may be ignored, e.g for panoramas where the viewer expects to have to scroll around an image.
Following the recommended resize and sharpen workflow above is THE best bet for success, trust me!
Image resolution, expressed as say 240pixels/inch is completely irrelevant for web use - only the actual pixel dimensions matter.
Never re-open a jpg to do this (unless that's all you shot with), always do it as the last stages of PP from RAW, or from a Tif or psd image file.
Never save the reduced size image 'over' the original (fullsize) filename
If you don't get the expected default jpg option when you click Save As, it's probably because you have not flattened a layered image, or converted to 8 bit.
Don't (for CiC image critique) host a huge image at PBase or Flickr (etc.) and then post an image url here using their re-sizing options like "medium" - it will appear here softer than if you do the down sizing and people will notice The answer, is to follow the instructions above
