Re: Photoshop Lab Color: Ch. 1
Why are you resizing 300 to 72 then back? Question: For the rgb version, I flattened, reduced size from 300 dpi to 72 dpi, then sharpened using unsharp mask, at (85, 1.0, 4). For the LAB version, I sharpened the Lightness channel in LAB using unsharp mask at (200, 1.0, 8 as the author suggests), then flattened, converted… -
Re: Photoshop Lab Color: Ch. 1
Yet another very helpful post John. Thanks for taking the time. Since I have been posting 72 dpi only, this wouldn’t help, right? By “original image”, I think you mean hi res (300 dpi)? I understand and agree. I’m just beginning to notice this, too. Yes, I think that’s the key, especially after reading the first of your… -
Re: Photoshop Lab Color: Ch. 1
Ok, I think I get that. If you change dpi from 72 to 300, you still have the same number of pixels, and the same file size, but now they will make a smaller image size. Yes, Ok. I'm getting it now. I'm afraid I lost you there. Here is the way I was taught to change a 300 dpi image for uploading to the web: Open an… -

Chapter 2 Thanks David. It helps me to write it down and post work on each chapter, and maybe it’ll help someone else too. The results I'm getting so far are great, but it leaves me wanting a better understanding, so I'm determined to keep going. I’ve studied chapter two and understand that: Positive numbers indicate warm… -
Re: Photoshop Lab Color: Ch. 1
Displaying an image in Smugmug or elsewhere on the web has absolutely nothing to do with the dpi. You are right that if you keep the pixels the same and change the dpi from 72 to 300, the labeled image size will go down, but that's just a label on the image and hardly anything these days uses that value so I just ignore… -
Re: Photoshop Lab Color: Ch. 1
By "original image", I meant a full resolution image (the original pixels with no resizing) that you haven't yet done post processing on. Then, we could see for ourselves what influences sharpness the most in that image. For the web, ALL that matters in this regard is how many pixels the image has. An image with 12… -
Re: Photoshop Lab Color: Ch. 1
I'm new here, so please forgive me if I screw up my reply... an old thread anyway, so may go unnoticed My understanding of some of the things John brought up here are a little different, so I thought I might post them to try to stimulate further discussion, and help better my understanding. Concerning the quote above, the…
