Photoshop :: Sizing Up A Jpeg That Has Artifacts For...
Jun 16, 2009
I have some really good resoloution images for a large 8x4ft poster project. but one of my clients larger images (an important one) is just a 1000 x 1000px image @ 72dpi that has some artifacts which needs to occupy a approximate 25 inch square on the final print. I can't get a better quality image than this from the client at this time as they don't have it. what techniques can I use in photoshop to increase the print size while improving the final printed image. In the past, I sized up the image to the size needed and set the dpi from 72 to 300dpi (using "bicubic smoother"), add some surface blur, add monochromatic, uniform noise @ 2% +/- (to help smooth out the artifacts). with this image now, there are a lot of flat shiny surfaces where the artifacts are more noticable, etc. what kind of techniques would you use for this kind of job? (apart form hitting the client xD)
We've encountered a huge problem with some JPEGs we retouched for print.Either directly after opening them in PS or after saving and closing the image (mostly the case) it's getting some kind of horizontal stripes / artifacts. Problem is, sometimes they only appear after saving the image, so we'd have to reopen every one a few times to make sure this error does not occur. Also, the images look abolsutely fine in the preview AND wehen placed in InDesign. Sometimes they're visible in the exported PDF, sometimes they aren't and we eventually find out when the product is already printed. Â We're running CS6 on OS X 10.7.5 with newest patches and Updates. All images are HQ stockphotos from familiar sites.
I need just a bit of help with an image that I am trying to correct. Am having no problem with the color levels or the brightness/contrast. My problem is that after I have adjusted all the needed levels, brightness/contrast, etc I am stuck with an image full of what I call artifacts. I have tried everything I can think of to clear this up but obviously there is something I am missing. Hope someone is able to help me with this. The image that is posted is the original that has been untouched.
I am creating 3D renders in PS CS6, and I am getting strange blocky artefacts in the renders. These appear on first pass and persist throughout the render. This has happened in the last 2 renders I have tried - I haven't used 3D for a while before this and I don't remember these before. Â By blocky artefacts I don't mean the JPG artefacts created by the forum's degrading of the uploaded image, but the light coloured rectangular blocks around the "s",On Win7x64 with latest PS CS6 update; NVidia 650M2GB on a Core i78GB.
Iinstalled version of CS4 v11 with no plugins and all settings at the defaults. If I go to Help > About Photoshop (and other menu selections) it causes a gray line to suddenly appear through the menu bar. If I then move my cursor over the minimize/maximize/close icons in the upper right, artifacts appear. .
i recently fixed a virus on my computer after a few days hard work tracking it down, and since then i have experienced no blue screens anymore, but i had a probel with explorer.exe where it used sometimes over 800MB of memory doing nothing. With more research and monitoring, i discovered its cause was actually a corupt music file on my desktop, and every time i refreshed my desktop, explorer's memory usage would jump up a few dozen more kb of memory.
This is now fixed. BUT, i still have one symptom of something wrong, that doesnt seem to go. My PC is back to being fast it seems now, and there is no noticable real lag between just opening folders like there was, but my desktop still has problems. If i close a full screen program, the computer doesn't exactly slow down, its just the program closes very slightly slower than normal because it closes from top to bottom.
MSN in particular, always leves it's title bar behind when closed. And if i click and drag on my desktop, the little dashed box it makes sticks and doesn't go away. All of this is resolved by a refresh of the desktop, but it doesn't explain why it is happening. Windows XP 32bitNVidia 9800GTX GPU4GB RAM
After using the Filter Extract and Magic Lassoo methods to erase a background of say a model, I usually end up with lots of artefacts.
I then use the backgound erase to remove these. But I find it very time consuming as they do not show up that well on the standard grey checkerboard background.
I'm working on a project and I'm painting a robot which is in a dark grey. I need to be able to paint in the shadows but Photoshop is going haywire with rendering the gradients. I'm simply using a round brush with 30% opacity and 20% flow. What I'm getting is some VERY ugly jaggedy stepping of tone.
My current project dimension are 5000 x 3000 px. I don't get what is going on. I have not changed blending modes, nor am I using any alternate modes on my brush. All the settings are pretty much out of the box, except for the global settings I mentioned above.
I'm a digital illustrator and I've been using PS for years and I've never run into this problem before. I'm runnin PS CS6 on Windows 7 pro with an NVIDIA GeForce 9800 GTX+ video card.
I'm having a weird problem in Photoshop CS6. I just installed it and I've been getting strange "artifacts" when I use the move tool. Also, when I work with text it displays poorly. It looks rough and not anti-aliased. I'm running Windows 7 64bit and have AMD 6850 GPU. Â [URL]...........
I am getting unwanted artifacts when I work with medium to large size brushes in Liquify. The artifacts look like lines of a few pixels width that are offset from the surrounding image area -- almost like pulling a couple of threads in a woven patterned fabric. This has happened with both large and small file sizes. It necessitates way too much retouching.
I use liquify extensively on images and didn't have this problem when I used Photoshop 7. It began with CS. I am now using CS2 on a G5 with OS 10.4. Any ideas how to solve this?
In images where there's flat colour (eg book & cd covers), how do you easily get rid of any unwanted noise, without making edges blurry, or resizing down?
Take this image below for example. It's essentially 5 flat colours. How do I remove the jpegging without blurring the colour edges any more than they are? (click to see full size, it doesn't look so bad squeezed down in a forum page)
I tried Filter > Noise >Reduce Noise with no luck. I thought Posterize would work but it's too harsh on the edges.
I have been a long time Photoshop user and am having screen redraw problems since I have purchased a new system. I did not have this problem on my Macbook Pro which was hooked up to the same monitor. Â Problem is: When I open a file in CS5 (12.0) and move the image around screen Its not redrawing smoothly. There is some stair-stepping artifacting going on. Its not lagging....just creating some stair-stepping like artifacting. Â If I open the same file in "Preview" (version 6.0) and recreate the same image movement there are no problems.
System is :
Mac OS mountain lion 8.0Â Mac Pro 3.2 Quad core (5,1) Â Monitor NEC PA271W (W/spectraview)Â GPU is ATI Raedon 5770 Â Monitor to Mac connection is DVI to DVI
I recently changed pc and monitor causing a damn problem with those color spaces! My monitor is a Dell u2412m and by default it's setted on: Â Now when I open a RAW file with ACR and choose sRGB as color space the result is this:As you can see, most of the photo presents black shadows. If I save the file and I open it with windows image it's perfect. Indeed, if I choose ProPhoto for monitor and for the photo the visualization is fine:
I must change the color space in sRGB or even RGB before save the final image so I really would like to se a real preview of it in photoshop instead of saving it first. So the problem occurs when I save to RGB (less artifacts) and sRGB (lots of artifacts!). I can't understand this because I'm using the same color space as default for my monitor.
The pc configuration is:Intel i7 3770 Ati HD7870 driver Ati 12.11 beta RAM 16gb
The Photoshop CS6 (13.0.4) selection, text, and shape tool causes colored artifacts on screen. I'm running on a retina Macbook Pro updated to the latest ML release. I have disabled GPU acceleration. I have also tried starting Photoshop with no plugins but this does not work.  I have created a video which shows the phenomena  [URL].........
Why can't I fix the size of my image in Photoshop? I try to make it, for example, 3.5" x 2.5", and have tried both the image size AND canvas size options. When I go and check the image size, it is 3.52" x 2.51", for instance. I've never encountered this before (using Photoshop 12 years now), and don't know how to fix this.
I am a digital scrapbook designer and I, and several fellow designers, have just started experiencing some odd behavior in CS. It is occuring on both Mac and PC platforms and in versions of CS3 through 5.  We create 12 x 12 in (3600 x 3600 px) 300 dpi documents used by our customers as "backgrounds" for digital scrapbooking kits. We save the documents as jpg's Basline Standard, anywhere from 8-12. Sometimes, if we open a saved jpg and place (drag) it onto a new 12 x 12 document, we notice that the saved file is just a bit and sometimes as much as an 8th of an inch smaller than the new document, even though they are both 12 x 12, 300 dpi. Additionally sometimes when we drag the saved files from Finder or Windows Explorer to a new document while holding the shfit key to center placement, we're still off by that same 8th of an inch. Sometimes, if we align the horizontonal and vertical, the same jpg will be perfectly aligned and no longer too small for the 12 x 12 document and sometimes you can very clearly see the edges of the layer beneath.  This issue is driving us nuts because it just started happening recently and our customers, who very often have their finished scrapbook pages printed, have also started noticing. I don't have a clue where start trouble-shooting this.Â
I have created a polka dot pattern (.125 inch) on Photoshop CS6. When I print it out at home it comes out perfectly. However, I need larger print outs so, I corresponded with FedEx print to make them for me. The issue is that the dots come out a bit smaller than .125 inch.
here's this picture. I need it to print at a 4x6. When I upload to order it with my lab online the cropping for the 4x6 crops out fingers etc. I've resized image tried several things.
How can I make this without losing my border, etc.?
Why is the default size of the print so large? Should I change it to just print 4x6's or leave it? Why does Save As change the size of the file and can this be changed? My photofinisher uses a Fuji Frontier printer. I am ordering PS Elements 2.0 for Dummies of which I clearly am right now!!
How do I size a picture in Adobe? Either before I make changes to the picture or after, I go to 'Image' then 'image size' and I try to change the dimensions of the photograph, but it automatically it refers to its own preferred size. How do I unlock it so as to adjust it to my likings?
I have been unable to print several resized images onto one single picture.
I have been resizing an image by selecting an area, copying, creating a new blank image via NEW>CLIPBOARD and then pasting the image onto the blank canvas. Then going to IMAGE>IMAGE SIZE and changing to the required size.
This works fine for printing one image but if I copy and paste a couple of images onto a new canvas the images are not the original size.
If I use 'save for web' and resize the image to a specific pixel width and height, how do I know if it is resized at 72 pixels per inch, 96 pixels etc? Are there specs for low, high, maximum quality in the Save for Web tool?
I'm trying to do is create a new background that is 4x6 then I want to drag and drop a photo onto it that is 4x6. When I do the photo is much smaller than the new background.
I have Microsoft picture and fax viewer that I use to show off my pictures in a slide show. I can get an awesome zoom to see minute details. How can I do this in Photoshop? Many times, the image becomes blury or pixelated. Some pics, I only want a small detail, so I try zooming in and using the marque tool to capture it and place in a new image, but it there a better way to do this to keep the clarity of the picture?
I have created an action to re-size images as I have 700 to do. BUT when I try to batch process I keep getting the Jpeg option box open to set image quality. This only happens when trying to batch process original straight out of the camera images. If I try to batch already saved images it works ok. Does anyone have any idea how to get around this? I'm using CS and Win XP home.
I have created a Photoshop image to print on a 8.5 x 11 inch canvas size (letter paper) and have scaled the document inside the canvas with 1/4 inches on all sides of the image. However shows that the image is over and above the allowable printable area for a letter size page.
I have to resize the image for printing to get the entire image in the letter size page. Problem is, the image gets off center once resized for printing.
Is there any set margins in photoshop or by the printer to require a border ? margins ? i am stumped as the image is within the 8.5x11" canvas size, but shows the image as larger (oustside the printable area) on the print preview....thinking there is some unwritten safety margins on the letter document i have missed.
Save for Web has an option for Image Size, it's a tab on the right side of the Save for Web window (Photoshop CS).
Well, I tried to resize the size in this window, saved the file, closed every open file and reopened that resized file that I had save with that resize option. Turns out that nothing was resized
I tried it several time, still the same size, even double checked in image/image size.
So what's going on here? I just discovered this option today and thought it would be useful to post images/screenshots to the internet... that is... if it works.
CS4 Is not allowing me to size the images as I would like.
I have PSD files that I need to size at- in this instance- to 11" Wide X 8.5" tall. CS4 will not let me do this.
When I try to size the image to fit the size I need one dimension gets thrown off. As I do not want to distort the image, I try to crop. (Cutting part of the image that has to be sacrifised to fit the size needed.) That will not work either. CS4 will not allow that change.
Once again what should be a simple task has become a miserable CS4 experience. Hours of reading instructions and watching videos is of no help.
Sizing an image to a given set of measurments should not be so difficult (and so far impossible).
