Photoshop :: Retaining Quality Of Edited Image
Mar 19, 2009
I have a JPG image that I want to edit with photoshop 7. I know that if I edit directly the JPG image and save again as new JPG image, the quality of the new saved image will be degraded. Experienced user know that because JPG is a lossy format.
I want to retain the quality of the edited image. Then I heard that the TIFF format is a lossless format that support compression.
I usually done this:
A. Let's say I have a JPG image that I want to edit, then I open the image and directly save it as a new TIFF image (with LZW compression).
B. Then I will do editing to the TIFF image.
C. After the editing TIFF image done, I will save it as a new copy of JPG image.
Note: Step C is only performed if I want to publish the image.
The questions:
1. Is the step A a correct step from the view of experienced user? I mean is this a step that I should do if I want to retain the quality of the want-to-edit image.
2. Does the LZW compression in TIFF give a quality loss in the image?
3. If I save a JPG image in TIFF format (with LZW compression), is there any quality loss (i.e., artifacts) in the saved TIFF image?
The next question is about saving the image as JPG in maximum quality for publishing.
Usually I choose these settings in the JPEG options:
* I choose "12" for the quality (the highest number).
* I choose "Baseline optimized" in the Format Options (There are 3 options available: Baseline ("Standard"), Baseline Optimized, and Progressive).
The questions:
- In save as dialog, there is "ICC Profile" checkbox. What is it used for? Does it affect the quality of the image? Should I check this option if I want to gain maximum quality image?
- Am I choose the correct option in the Format Options if I want to gain maximum quality image? What's difference of the three Format Options? What should I choose if I want to gain maximum quality of the JPG image?
- Is there any other factor that I must consider if I want to gain the maximum quality of the JPG image?

I've been trying so hard to upload high quality photos on facebook but the compression used by facebook is just so bad that all the hours used to edit the photos is left in vain. There seem to be an action uploadable on Photoshop to keep the quaity of the photo before uploading it to facebook. Is there a similar action/present for lightroom 5 as well?

My problem is related with the quality of a image.
My question is how to maintain high quality (original quality) of a image after resizing it?
If i resize it with same ratio like:
2816x2112px to 1600x1200px (4:3)
2816x1584px to 1920x1080px (16:9)
Mainly i use scale image option in Gimp. But now i need to resize many images for my work so i tried David's Batch Processor to resize my images. After using it, i found there is some quality promble with the resized image.
Then i tried, the scale option with, use quality setting from original image and JPEG quality parameter is 95, in gimp but the problem is same. I did it with also with David's batch processor- JPEG quality parameter is 95.
Other thing is that, the original image 2816x2112px (4:3), size- 3.6 MB is displaying in image viewer with 47% and the resized image 1600x1200px (4:3). size- 1.2 MB is displaying in image viewer with 83%, So my questions are: How can i check the quality of a image after resizing it, means the image is exactly same as the original? Or Is David's Batch Processor maintain the original quality of the images after resizing?. I realy need to resize many images for my work.

A while back I took a Photoshop class and remember a lesson on where you could select a region of an image and save it for the web with a high quality and select another region of the same image and save it for the web with a low quality, so that the focal point was saved with a high quality and the background was saved with a low quality. I have no idea where my notes are from this class and can not remember at all how to do this. Can anyone direct me to a tutorial about this?

I have Photoshop CS5 installed on my windows7 system. It was working all fine until last week. From last week, I am unable to save the photos that I edit in photoshop. Its like, I save them, but I do not find them anywhere, not in the folder I saved them nor anywhere else in the computer. I also tried saving the pics as a copy still no luck. This is a work environment.

I just got CS6 and have been working on some new images in RAW. Once I finished the editing I wanted to do in RAW, I saved the image as a JPEG, then clicked "open image" at the bottom of the RAW window.
The image that came up in Photoshop looked nothing like my edited RAW image. It's as if none of the edits ever occurred.

Well, it looks like I edited an image in ProPhoto RGB and now when I save as JPEG I get a color change (always looks warmer, like a change in white balance.)
When I convert to another profile, the color change. Is there anyway to either convert and get my colors back or as to JPEG with the color's I'm getting in photoshop? What is odd is I'll see a nice white background in PS and even in the thumbnail. But if I open it in anything but PS I get color change.

I have my photos on a separate volume at /Volume/Users/Lightroom Photos/…
Everything works fine except when I choose "Edit in Photoshop CS6", work on the image in Photoshop then save it. It gets saved back to the same folder as the original file, but when I tab back to Lightroom it just shows a square tile with a question mark instead of the new file. Tapping on the exclamation mark reveals that Lightroom thinks the new file is supposed to be in /Users/Lightroom Photos/…
For example the dialog box might say:
“_DSC3047-Edit.tif” could not be used because the original file could not be found. Would you like to locate it?
Previous location: /Users/Lightroom Photos/2012/2012-12-08/_DSC3047-Edit.tif
When in reality the original and the edit are both in /Volumes/Users/Lightroom Photos/2012/2012-12-08/ and there is not, and never was a /Users/Lightroom Photos/…
That is, something about saving back from Photoshop stripped off the "/Volumes/" from the beginning of the path. I can choose Locate and find it right where it should be and it will show up. Once it shows up the image tile shows the image but has an exclamation mark; tapping on that brings up a dialog box that says:
The metadata for this photo has been changed by both Lightroom and another application. Should Lightroom import settings from disk or overwrite disk settings with those from the catalog?
This is on a Mac and so /Users does exist but that maps to /Volumes/Macintosh HD/Users. I wonder if either LR or PS is confused by there being a /Users and a /Volumes/Users.
Editing in a Nik Plugin (e.g. Silver Efx) works properly, FWIW.
I am using LR4.2 and PS CS6 13.0.1 on OS X 10.8.2.

I have a rectangular box in perspective on a layer, I want to stick a picture on it , so I can use the Vanishing point filter (creating a right plane, copy/ paste that picture and placing it) and it works fine. But I have the same picture to do with a hundred of picture to stick, so I need that to be dynamic. I only had to right click my layer with dynamic picture, "replace content", and it auto-fills in the other layer with the vanishing point edit.

This keeps happening where I have an image, I edit it, I press ctrl+S, but when I upload the image the edited version is not uploading the original version is?? I have to save it as ctrl+shift+s. This sucks because now I have 3 or 4 of the same image all saved differently which gets to be pretty inconvenient.

A thin white border around the figure that I had edited appeared out of nowhere. I was able to erase it before editing the background but now I can't erase it or remember how I did that.
how to get rid of this line? If by setting the eraser color to the background color, how do I do that? As I get rid of the line, I'd also like to refine the figure's outline so it becomes cleaner.

I'm using a Coolpix 8800 and I am increasingly disatisfied with the results. Very few of the images that I take with this camera appear to me to be properly in focus. They seem to have a sort of soft focus effect.
This sort of chimes with a review I read recently in a magazine which gave it very poor ratings for the autofocus.
I am also not sure if I am expecting too much from it? Many images seem fine when viewed as fitted to screen or print size (viewing on LCD montior 1280/1024 screen resolution) but it's when viewing actual pixels that what I think is the poor results of autofocus are shown. Is something like screen resolution introducing an effect here that is illusory?
I'm shooting tif files and editing in CS2.

When you reduce the image quality of a jpeg image , How exactly is it reducing the quality? is it applying file compression , reducing bit depth or is it reducing the sampling rate of the image? or anything close to the above....

I had CS5 installed over a year ago and running without any display problems until recently. About a week ago I noticed severe banding in the high light areas of my images when I opened them in PS. At first I thought there was something wrong with my camera, or just plain bad images, until I realised that the images display without any banding in Windows Photo Viewer or any other viewer! I'm running Windows XP SP3.
I have not made any hardware, software or other changes recently (except installing a Nik S/W plugin – which I subsequently uninstalled but that did not solve the problem). Also no changes in colour profiles etc. I also updated CS5 to the latest version; disable/enabled Open GL acceleration in the preferences without any effect on the problem.

I run photoshop CS3 and I just created an image, saved it as a jpeg and uploaded it to my website. The image looks great when I open it from the folder in the computer but on my website it has lost quite a bit on image quality.

I'm Trying to make a Headshot. Using my (Epson Perfection 1260)Scanner, I scanned a Back and White(4"x6") Sharp Image Photo at (1200 dpi) and enlarged it to(7"x 9").
Using PhotoShop I Sharpend the Image. I printed at (1440 dpi) using Glossy Photo Paper with my "Epson Stylus Photo 750" Printer. The Image has turned out Grainy and not very clear as the original although it did manage to pickup up detail like lint on the photograph LOL.
I tried enlarging the image in PS and increased the amount of Pixels, instead of during the scanning process but that resulted in poorer quality image.
The Photos that remain the same size as the original turn out excellent photo quality images.
How do I enlarge a photo from a smaller image and maintain almost the same quality as the original? It seems I am losing resolution somewhere along the way.

Ive been using PS6 for a while now and Ive always struggled with trying not to sacrifice image quality with reasonable file sizes.
I normally use a image size default setting of 800x600 with a resolution of 300 pixels/inch for most of my work.
But when saving for the web or using Image Ready to slice up more complex images I always have to bring the quality of the image down to about 25-35 to get some reasonable file sizes.
With this I get a lot of fuzzy images.
My question should I be doing something different from the start regarding my image size and resolution.
Are there any other setting I should consider when optimizing the final image.

When saving a jpeg it gives the option of inserting a number on quality. I have mine auto set to 10 but I have no idea whether 1 is better or worse or what number I should be putting in to preserve the original quality?
