Insanely over-sharpened images
The finished product in CS2 looks fine, yet when published, the
image(s) tend to look like this: http://www.pbase.com/sirchandestroy/image/64425933 Workflow: 1) NEF tweaks in RSP 2) 16 Bit TIFF in CS2 3) color/curve/saturation/xxxxx filters/whatever 4) sharpening - generally the generic filter-sharpen option (as in this case); sometimes smart sharpen, sometimes unsharp mask Anyway, in CS2 they look fine; when published as 800x600 8 bit JPEGs, they look horrible. I have been trying out Adobe RGB II lately - could this be part of the problem? Thx, B |

You never have too much information. The OP graciously reposted to rec.photo.digital, and despite considerable posting of gobble-dee-gook, the correct answers did pop up. I was impressed with the OP's figuring out the specific problem, while others pointed at the generalities involved. The general problem is that sharpening should be done as the absolute last step in manipulating the image, and particularly it should be at the final size/resolution. Any resampling will necessarily result is less than optimum results. The specific problem the OP saw was that when posting to the web, you are not there when the last bit of manipulation is done! The web browser is very likely to resize the image, and when it does so the results are unpredictable. Hence, for use on the web, it is a good idea to do minimum sharpening and to resize the image to approximately the *expected* display size first. (An 8mp image is indeed wonderful, but if it is displayed entirely on a 1024x768 screen it *obviously* is going to be resampled for display, with significant affects on sharpening done at the original size. It is far better to size the image at 800x600 or less and have the server specify the actual size, e.g., "width=800". That reduces the chances that a browser will resample for display.) -- Floyd L.

Yes, and I wish Photoshop would "warn" you when you have already sharpened the image once....I am always forgetting, and resharpening it again after I have made some other corrections.....You can backstep, but only actively....I wish you could backstep passively, or just get a listing of what you have done, so you'll know to not do it again. |

Ah grasshopper, but you CAN have a detailed listing of all the changes you've made to a file. Which version of Photoshop are you using? Here's how to do it in CS2: First go to your Photoshop Preferences (Edit / Preferences / General ) On the General tab, make sure the checkbox for History Log is checked. Set the "Edit Log Items" setting to "Detailed." After restarting Photoshop (to make it accept the new Preferences) you can now view a detailed log of what you've done to each file by going to "File / File Info / History." Photoshop will now record the settings you use for each step of the operation. This can be handy if you decide a few days later to go back and make some minor changes to the file. |

I have a convention where I save a copy (with a distinctive name) of an image when it has been "finished". That does *not* include sharpening or sizing. From that "finished" file any number of "final product" files can then be generated. They are sized as appropriate for a specific use, and the last step is sharpening before it is saved with a distinctive name to indicate the file is a "final product" that should never be changed in any way. If that, for instance, is a file intended to make an 8x10 print, and there is a call for a 16x20 print, the work starts one step back, from the "finished" file, which is once again used to generate a new "final product". -- Floyd L.

I have a convention where I save a copy (with a distinctive name) of an image when it has been "finished". That does *not* include sharpening or sizing. I need to do this, too, but I need to number my film frames and slides, and then use that number in the names....I also need to start saving the primary scans in something other than JPEG compressed format. Whenever I go back and change anything I am resaving the compressed image which is supposed to be bad for the image quality. From that "finished" file any number of "final product" files can then be generated. They are sized as appropriate for a specific use, and the last step is sharpening before it is saved with a distinctive name to indicate the file is a "final product" that should never be changed in any way.

Yes.....My chief problem is organization.....I am not very well organized. I don't print anything, but just view them on the computer screen. I should save them in more detail, so others could print them in the future. |

Unfortunately, I only have version 7, and your instructions don't work for me....But there may be another way, so I will investigate it. |
