Photo Editing Software Programs,
Photoshop Unsharp Mask
Cool photo editing software programs and Photoshop effects tutorials on image sharpening are talked about on this page.
Now it's time to resize the image and sharpen it. Soooooo, update the link in the InDesign page and choose the Direct Selection Tool (the white one) in the Tools Box and click on the image. This will tell you its size (percentage). In this case, it's at 57.893%. Our mission is to resize it to 100% through Photoshop.
Reopen it in Photoshop and bring up the Image Size box again. We're concerned with those areas I have highlighted in red. Make sure those boxes are checked, especially Constrain Proportions and Resample Image. Then change the Document Size unit drop-down list to Percent and paste 57.893. Since Constrain Proportions is checked, the size will be, you guessed it, in proportion. Press OK.
With the image at 100% it is safe to sharpen. In other words, the only time to sharpen is when you have decided the image's final size.
In CYMK, I sharpen only the black or K channel. In Photoshop, put your image at Actual Pixels (Ctrl-Alt-0) and go to Filter>>Sharpen>>Unsharp Mask.
Through trial and error, I have settled upon the Threshold (1.1) and Radius (2) settings, and keep these for every image. Only the Amount changes. The trick is to take the Amount to its highest number before halos appear. In the example, I've shown what it looks like at 500%.
In the end, I settled for 200%.
A good rule of thumb is: the larger the photo, the higher your Amount. For the pix on hdr-photo.org, I sharpened from 60-75%.
There, we're done!
Awww, not so fast. What if there are people in the photo? Yes, I almost forgot. We need to adjust their skin values.
You may also be wondering, "I don't work at a newspaper. What do all of these photoshop effects tutorials have to do with me?"
Well, have you ever taken your images for printing at the You-Shops? My advice is if you are armed with photo editing software programs like Photoshop, prepare your pix before you tackle the store's imaging machine. You can fine tune them easily and cut a lot of errors and confusion that might pop up at the store.
Basically, this newspaper tutorial can be applied to pre-photo lab preparation; with just a few changes. Keep the image at RGB and don't change it to CMYK because the You-Shops don't process CMYK. Also, the resolution is upped to 250 or 300 ppi. And be careful with the sharpening since you're not doing it in CMYK's K channel.
