Default Luko's Sharpening Method - For Luko

Hello Luko / guys and girls :p

I've installed recently Photoshop CS 2 and i'm discovering great tools for post-processing photos.

Today, i've tried your Sharpening Method... but i'm not obtaining your clean and sharp results... here's what i'm doing:

-USM: effect 18, radius 40, threshold 0
-USM: effect 150, radius 0.3, threshold 0
-go to edit, then fade USM: opacity 100%, mode darken
-USM: effect 150, radius 0.3, threshold 0
-go to edit, then fade USM: opacity 50%, mode lighten


1.You do this after the resize right?
2.Do you aply any contrast/shadows/saturations adjust before aplying the action? or after?

Thanks for your help
Mario

I remember this method, but I wondered: do i understand these 5 steps have to be done one after the other, or to choose between one of the five?

thanks, Luko, if you can answer to this!

that sounds about right, but I would urge you to do this on a duplicate layer, this way after all of it is done you can change the opacity of the layer or apply it only in spots using history brush(which I have learnt also from Luko - hope this guy doesn't start charging for his lectures;-).

I do all other adjustments before.

Hi Mario - Until Luko stops by I'll share a bit of my process, which includes a variation of the sharpening described by Luko. The settings I use are slightly different, though it too is a five step process with two fade steps in third and fifth place. I work with 12.8 MB RAW files. I'm working in CS, not the newer CS2. Because of that I can't open CRW2 files from my new Canon 5D within Photoshop. I download images with Canon software, then open them in Digital Photo Professional. I may adjust white balance or change photo "style" but I do my major post processing in Photoshop. I transfer the individual files as TIFF files into Photoshop.

I orient the full-size image first, rotating if necessary and then cropping. I apply levels and/or contrast, and if warranted will adjust saturation. Finally, I apply the "Luko Sharpening" protocol. AFTER that I convert the file from 16 bits to 8 bits, and resize for display either on TE or my personal website. The last step I do before saving is to run USM one last time. I use relatively low settings of 60%, 0.3 radius, and 0 threshold. That sharpening cleans up the file that has been resized. My understanding is that sharpening should be done as the final step in processing.

I hope this is useful. I can't tell from the information you post with your photos, but if you haven't already started to shoot your files RAW I'd heartily recommend it. Yes, you get fewer images on your compact flash card, but you also give yourself greater freedom in post processing. Good luck.

All the actions on saturation, shadows, curves, etc. should be done before on full size 16 bits pics. (but you'll see that there is something that will modify your contrast with sharpening, so you have to get accustomed to it in the long term)

then resize your image to 1500 pixels (still 16 bits)

sharpen as mentioned (To Hervé : 5 Steps! This is not a sharpening supermarket, where you chose whatever you like...). Peter is right : better on a layer

Resize to 800 pixels (you can also achieve a very very slight sharpening afterwards to get an additional pop, like 30 at 0.3 radius), convert to 8 bits mode. Save as. Upload to trekearth, don't forget a caption.

Cheers
Luko
