diamante67 Posted February 25, 2016 Share Posted February 25, 2016 (edited) I received the attached photo from a family member - it is a tiff file of dimensions 0.8"x0.8" (approx) and 6400px/inch. Could I get some advice on how to deal with the noise, and also if there is any way to improve the lady's eyes? My general plan is to mostly clean up the scratches with cloning/healing, reduce the noise, brighten a bit and bring out a bit of clarity. Would the file be decent enough to print in 8x8 format? Any other advice? I am adding a couple of 700x700px snippets as well. Edited February 25, 2016 by diamante67 Link to comment Share on other sites More sharing options...
Damien Symonds Posted February 25, 2016 Share Posted February 25, 2016 Did you scan the photo yourself, or were you sent the digital file? Link to comment Share on other sites More sharing options...
diamante67 Posted February 25, 2016 Author Share Posted February 25, 2016 no I did not scan it myself. Someone else did, and I do not think the original is available. Does it look "fishy"? Link to comment Share on other sites More sharing options...
diamante67 Posted February 25, 2016 Author Share Posted February 25, 2016 i was also sent a file of the same dimensions that looks like a negative. So maybe they scanned a negative and possibly used some software to convert it? Link to comment Share on other sites More sharing options...

Does it look "fishy"? Well, no, it's just not ideal to be working with a grayscale file. Better to have an RGB file if possible. But it's not the end of the world. 23 minutes ago, diamante67 said: i was also sent a file of the same dimensions that looks like a negative. Is that one also grayscale mode?

diamante67 Posted February 25, 2016 Author Share Posted February 25, 2016 (edited) Wait, I forgot to add that to the first one I posted (original post) I changed the color profile from SFprofT to sRGB, because everything was looking blueish, and I also added you b/w conversion. Since I was worried about the grain and details I did not think of mentioning these steps. The negative file came in as "generic RGB" and, as I said the tones are not exactly grayscale.

Damien Symonds Posted February 25, 2016 Share Posted February 25, 2016 Oh! Ok, well, definitely use the RGB one. Can you post it, and a 100% crop from it? Link to comment Share on other sites More sharing options...
diamante67 Posted February 25, 2016 Author Share Posted February 25, 2016 not sure if you want the negative but, here it goes. I am adding the detail from the inverted picture. Link to comment Share on other sites More sharing options...
Damien Symonds Posted February 25, 2016 Share Posted February 25, 2016 Thanks! I think you said it was a tiff file. Is it 8-bit or 16-bit? Link to comment Share on other sites More sharing options...
diamante67 Posted February 25, 2016 Author Share Posted February 25, 2016 It is a TIFF. I "think" it was 16 bit but right now I am at work so I cannot check with photoshop. I re-downloaded the image and it shows a bit depth of 64... I am not sure what to make of that. The photometric interpretation is RGB. Here is the other data Link to comment Share on other sites More sharing options...
Damien Symonds Posted February 25, 2016 Share Posted February 25, 2016 Yeah, 64 sure is weird. Link to comment Share on other sites More sharing options...
Damien Symonds Posted February 25, 2016 Share Posted February 25, 2016 Anyway, this looks very promising. Can you do a couple of things for me? First, go to Edit>Assign Profile, and change from Generic RGB to sRGB. Then, add a Levels adjustment layer, and Alt-click on the "Auto" button in the Levels dialog. Make sure it's set to "Enhance per channel contrast", and set the shadows and highlights clipping to 0.01% each. Click "Save as defaults" then hit OK. Save that (keeping it as a tiff is fine, or change to psd, either way is ok.) Then, show me the photo and the 100% crop again. Link to comment Share on other sites More sharing options...
diamante67 Posted February 25, 2016 Author Share Posted February 25, 2016 glad to hear you think it is promising. I will do as you suggested tonight... could you clarify whether I should work on the negative or on the inverted negative? Link to comment Share on other sites More sharing options...
Damien Symonds Posted February 25, 2016 Share Posted February 25, 2016 The inverted one, I'd say, as long as it's 16-bit. Link to comment Share on other sites More sharing options...
diamante67 Posted February 26, 2016 Author Share Posted February 26, 2016 Confirming the file was 16 bit. Here is the new 100% crop after following the steps you suggested. 1 Link to comment Share on other sites More sharing options...

diamante67 Posted February 27, 2016 Author Share Posted February 27, 2016 (edited) here it is. It is interesting because to me they seem all kind of the same, detail-wise; I am glad you think it is promising Unrelated, in the future how do I manage posting pictures given the max total size? I assume that if I clear up my earlier attachments then the images get lost? Edited February 27, 2016 by diamante67 Link to comment Share on other sites More sharing options...

Zoom in to 100% view, then go to your Channels panel. Click on the word "Red", then "Green", then "Blue". Compare them I think you'll agree that the red channel has the nicest quality detail.

When I uploaded the last image, I initially saved it with minimum compression. The file was about 9MB and it failed to load. The error pointed out to the max size of the attachments but, given that my file was less than 19MB, it made me think that I had reached some maximum amount of "storage"? for the attachments. I then re-saved the file with slightly lower quality (5MB) and the file uploaded with no problem. Link to comment Share on other sites More sharing options...

So, am I supposed to only use the red channel? If so, at what point in the workflow would you recommend doing some noise reduction? Link to comment Share on other sites More sharing options...

Damien Symonds Posted February 27, 2016 Share Posted February 27, 2016 If so, the next step is to add a Channel Mixer layer, click "Monochrome", and enter 100% for the red channel, 0% for the other two channels. Link to comment Share on other sites More sharing options...
Damien Symonds Posted February 27, 2016 Share Posted February 27, 2016 Then press Ctrl Alt Shift E to create a new layer above. On that layer, go to Filter>Noise>Reduce Noise. Apply it to your taste. Then start the patient cloning repairs. Link to comment Share on other sites More sharing options...
diamante67 Posted February 27, 2016 Author Share Posted February 27, 2016 I swear, you got to be the God of the Channel Mixer! Thanks for all your help and, yes, I agree that the red channel is the one that looks the cleanest and nicest. Thanks again! Link to comment Share on other sites More sharing options...
