Photoshop :: Image Quality
May 27, 2006
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.

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?

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.

I’ve been using PS6 for a while now and I’ve 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.

How can I make the quality of the image better? everytime i draw something, then zoom in, it becomes extremely pixelated. does that mean i have to draw on a bigger canvas? is there no way to make it high quality without drawing on a bigger canvas?

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?

I initially had the issue with Photoshop CS5 not being able to recognize RAW files from my Nikon D800. I managed to sort-it-out by installing the RAW Plug in 6.7 hence now CS5 opens up the RAW files from D800.
Â
However, now I'm faced with the different issue. I see a significant drop of image quality when RAW s are opened in CS5. The images looking stunning with in D800 display screen looks very dull and flat when opened in CS5. No where close to the brilliant colors shown in the D800 preview.

I have an image that is about 72 DPI, but I want to increase the quality of it. I also have another image that is 300 DPI, but looks the same in quality to the 72 DPI one. Is there a way to improve the resolution on the latter image as well?

I don't know how to explain it properly, but recently if I download a picture and open it in Photoshop is appears rough and edgy. For example, I just recently downloaded this.
However, when I attempt to open it using Photoshop is appears like this. (I couldn't open the screenie in Photoshop as the quality was reduced even further)
I just started using Photoshop recently, but when I first started using Photoshop it didn't do this. It happens, I now know, with any image. Even those that were never downloaded such as the screenie I provided have a drastic decrease.

I am creating an invitation in Illustrator which I then place into photshop to create a JPEG. I want to create a high quality JPEG version of it but with a low file size because I am emailing the invitation. Am I correct in placing the image into photshop or should I export it from Illustrator. The image is built of of vectors and one JPEG but they are not high in quality.

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?

PS7 on Win XP
Windows Explorer and some software bundled with digital cameras [Canon and Panasonic] warn when rotating a picture that there may be loss of image quality. Presumably it must re-compress the jpg image file?
In order to avoid that problem, I have been rotating image files in PS7, since no such warning comes up there.
Is there loss of image quality by rotating or cropping in PS7? I usually save jpg files at quality level 10.

I am doing the artwork for an album I am working on and need some help resizing the cover image. As of right now the image is around 3000x3000 resolution, but it needs to fit on a 5.5"x5.0" template. I copied the image from photoshop into illustrator and used free transform to scale it to the correct size. However, the image was pixelated and unusable. So I basically want to know the best way to do it without losing quality. Also, should I add the text before or after its been resized?

I use Adobe Photoshop CS, and I was wondering if anyone could help me with a problem I'm having with resizing images.
I'm wanting to resize an image from 485x391 to 100x81, but when I try to do that, the image quality is completely degraded and it goes blurry where the finer details are.

I have a couple or three (probably more) small-ish sized images that have crappy quality (they're grainy/noisy-ish and whatnot y'know).
My question is: in general, what would be the best way to enlarge the photo, make it look smooth, and more/less "professional quality" without losing any color? I know whichever method of doing this would require playing around with the settings in each step with each picture.

I recently got a new computer. I use CS3 to edit. For some reason, whenever I resize the image, save it as a Jpeg and post it to the web, it loses image quality. Severely. I've never had this problem before....until this new computer. I usually resize the image to 800, then simply click on Save as Jpeg. Â

when saving an image as a JPEG I would click "Save As", select my folder and the Image Quality dialog box would pop up and I would then select 12/Maximum as the image quailty and hit "OK". Thereafter, every time I saved an image, Photoshop applied the same settings as the previous save i.e., 12/Maximum was pre-selected and I would just hit OK and move to my next image.Â
Â
However, since yesterday Photoshop is no longer pre applying the last setting used and is defaulting to quality 8/High every time. Si everytime I save, I am now having to slide the slider to 12 which is kind of interrupting my work flow.
Â
I have tried delete my preferences settings in the hope that this glitch would be fixed by resetting the program, but the problem persists.

simple terms the following options in the JPEG2000 dialogue box :
Â
-Wavelet Integers and Float. Explain wavelet in idot proof terms? What is the difference between the two types of wavelets?
Â
-Tile size. What does it refer to when it says Tile? What's a tile in this instance?
Â
-Region of Interest. What does "controls the quality within the image by using an alpha channel" mean?

I would like to enlarge an image, but when I do this it loses quality.Â
This is how I have done it: image > image size > check "resample image" > select "bicubic smoother" > set my dimensions.

I am using an image for a contact icon on a business card, but the print quality of the image is bad.
Â
Now will it work if I convert the image to a smart object and print the image like that? (The original image is a much larger png file that i convert to a smart object then resize it to icon size)
