Image resolution and zooming

I'm working with Photoshop CS4 and one feature that I really liked was the fact that no matter how much I zoomed in or out of an image, it never looked pixelated or distorted. Unfortunately, this has suddenly stopped working. Some zoom levels look fine, but every other one looks really bad.
I tried restarting the computer, looking through preferences, view, and image options, but was unable to find anything to fix it. Anyone have any suggestions?

Check the status of OpenGL drawing in preferences.

Check image resolution and color

Please let me know whether it is possible to get the image resolution and color used in a eps file.

Sashi

You can specify the resolution for exporting, for document etc but resolution of the raster objects can not be retrieved.
Color space of the raster object can be retrieved using the rasterItems : colorants or imageColorSpace properties

Exported Raw Conversion Image Resolution and Assigning a Color Profile, etc

In Aperture 1.1, although I set the exported Raw conversion image resolution to 300 dpi in the preferences, it continues to come out at 72 dpi which is something of an inconvenience. Also, is it possible to assign a color profile to the "exported version" so that it is congruent to my PS CS2 color workspace (if that is what its called). Is this program capable of carrying out a conversion as a background operation? Finally, can the layout windows be configured so that they remember how they have been used in the past? Thanks.

Iatrogenic huh! Cool!
Anyway, I'm not real clear on what it is you are trying to accomplish. Despite your obvious vocabulary skills, there seems to be some disconnect relative to what you are trying to accomplish. You are right that "exporting a version" in Aperture is roughly equivalent to what happens in ACR when you "Open" a RAW image into Photoshop. In both cases you have, hopefully, already done the adjusting of parameters you want prior to "exporting", or "opening". When you "open" or "export" you wind up with an "image" composed of pixels, whereas in the RAW adjustment phase you are just working with a temporary thumbnail and a set of mathematical instructions. Big difference, I suppose is that when you "open" and image from ACR into CS2, the resulting image is truly just pixels and has not had a "file type" applied to the file yet, until you "save" it, while in Aperture, if you "export" a file to CS2, or to the desktop, you end up with the file type already applied. Presuming you "export" a 16 bit TIFF or PSD, there is no operational difference.
I could be wrong, but with the new Bayer Demosaicing algorithms in Aperture 1.1, and the Camera RAW adjustments, you should be able to come up with an adjusted image that is VERY close if not identical to one done in ACR, with the possible exception of lens abberation adjustment. I was very critical of the RAW adjustments in 1.0.1, but I am very happy with the capabilites in 1.1. That said, I think there is still some room for improvement in user friendliness of some of the adjustments such as Levels.

Original Image Resolution and Color getting Distorted

Hi All,
I am using JAI for reading images from a source i have to read the images and than have to split the images
initially i was using ImageIO.read() method to read images but for some images it was throwing error as
javax.imageio.IIOException: Unsupported Image Type
     at com.sun.imageio.plugins.jpeg.JPEGImageReader.readInternal(Unknown Source)
     at com.sun.imageio.plugins.jpeg.JPEGImageReader.read(Unknown Source)
     at javax.imageio.ImageIO.read(Unknown Source)
     at javax.imageio.ImageIO.read(Unknown Source)
     at deepzoomconvertor.Main.loadImage(Main.java:370)

     at deepzoomconvertor.Main.reteriveAllImages(Main.java:221)
     at deepzoomconvertor.Main.main(Main.java:86)so in such exception cases i am trying to read the images using JAI and i am successful in reading images
here is the piece of code i am using for this
BufferedImage result = null;
   SeekableStream ss=SeekableStream.wrapInputStream(new FileInputStream(file), false);
           ParameterBlock pb = new ParameterBlock();
           pb.add(ss);
           RenderedOp rm=JAI.create("JPEG", pb);
           result=rm.getAsBufferedImage();
             return result;it able to split images but the quality of images are poor it losts its original color format.
can any one have any idea how to do it while retaining the quality of image color and resolution
Thanks in advance

The JPEG you are reading is a cmyk color space one. They're not common, but they do occasionally pop up in a collection of random jpeg images.
The default JPEGImageReader that comes with the jdk cannot read them. And it will throw an exception - the exact same one you got - stating it can't. JAI's behavior is a little worse. It will read the image without exception, when in fact it to can't read it. It doesn't handle the cmyk aspect right, so you get a messed up image.
The native JPEGImageReader that comes with installing [JAI-ImageIO|https://jai-imageio.dev.java.net/binary-builds.html] can read them. It appropriately decodes the ICC_Profile embedded within the JPEG and you get a cmyk BufferedImage. But if you wish to render this TYPE_CUSTOM BufferedImage, go grab a coffee while you wait for it to slooooowwwllly paint. You'll have to do a ColorConverOp to turn the cmyk BufferedImage into an rgb one (so Java2D can render it fast).
Having done all this you'll find that 1) ColorConvertOp makes the image too bright and 2) The native PNGImageReader that comes with installing JAI-ImageIO has an affinity for returning TYPE_CUSTOM BufferedImages (arggg!!!).
I'll help you fix points (1) and (2) if you get that far. Maybe the best choice is to simply give up on cmyk jpegs. They're only used in printing press environments, and people only use color space aware applications (like Photoshop) to manipulate them in any meaningful way.

Image resolution and ipad3 retina

I have just screenshot an ipad home screen from an ipad3 (with app buttons etc) and wish to place this into indesign as a mockup for a client.
I have tried so many variations on resolution in Photoshop, making sure its placed in at 100% in indesign but it never looks crisp?
Any suggestions on resolution and pixel size would be much appreciated!
Thanks,
Nick.

Thanks for your reponse Bob,
The image is fine in photoshop and a little worse in Indesign (display performance: High Quality), but when viewed on an ipad3 retina it isn't as hi-res?
The image I screen shot is 2048x1536. Placed in an Indesign 1024x768 document at 50% with Actual 72ppi and Effective 144ppi.
Is there something I'm missing?
Thanks,
Nick

Understanding image resolution and appearance across devices

I used CS6 standard.
Why have some images have soft edges under retina (iPad 3) but sharp on a screen (non-retina)?
Does this mean I will have to rework all my images to work with retina display? As most of my images are 72dpi, not sure if this relevant or not?
Can someone kindly advice me the best ideal way to overcome this problem.

Paul, Yes, I can see where you are coming from. You have given me something to think about cropping.
Yeah, the proportions of the iPad3 are a bit off; I usually send out 600x400 pixel images - I find the proportions pleasing - for display on, mostly, social networking sites etc, and while most people up 'til now have considered 1080 vertical to be "HD" (LOL!!!) that's been good enough.
The Retina Display on both the iPad and MacBook Pro, is something of a game-changer image quality wise; we're now hearing rumors of an iMac with a Retinal Display! While that's still in fanboy nerdgasm territory - I've not seen any leaks out of the Apple supply chain about them having been sent sample displays - I think it really is just a matter of when, not if.
Mind you, I for one will be happy if these new HiDef displays dissuade people from posting their scuzzy fonecam pics all over the web (LOL!) as c.pfaffenbichler indicated above, pixels is pixels!!!

Scanning of Film Prints by Processing Labs - Image Resolution

I shoot a fair amount of film, in addition to digital, so I usually scan my own photos to be able to use the image editor. I've asked around to the run of the mill photo labs (wally world, costco, kmart, etc) about having my images output to picture CD and there appears to be quite a bit of difference in the image resolution and output format they offer. Many of them can't top my basic flatbed scanner.
anyone have any insight into this, or suggestions for where I might go to get a 5MP output image tif?
Most of the photo labs offer jpg at around 1600 x 1200
thanks!

My comment came about for 3 reasons:
1) I have come across quite a lot of people who either buy or save up for DSLRs who don't need them. They just think it's the only route to good pictures. The reality is that, in some cases, they never get a good pic because the cameras are too complex. The main thing is to be aware of the options.
2) For the last 15 years of film photography [I gave up film 3 years ago], I used SLRs. There really wasn't a choice. I started out with a bag full of lenses, which I lugged around. I missed loads of pictures because I hadn't lugged it. In the latter few years I started using "super-zoom" lenses - 28-200 and then 28-300. The effect was that I just didn't need any other optics. I was still carrying a camera weighing about 1Kg, but that was an improvement.
3) For me, photography is about taking pictures. Period. I come across so many people who are obsessed with all the equipment. They buy all the mags and are always hankering after something new. I sometimes wonder if they ever take any pictures [other than all those "test shots"]. I've had the same digicam for 3 years. I might upgrade it soon, but I'm not in a hurry.

How to change image resolution in oracle forms.

Hi Experts,
I am working on oracle forms 10g (Windows7 OS). Can we get the image resolution of an image item in oracle forms? Can we resize the image in terms of resolution?
I have a requirement where user can upload only 1280x720 size images. Either i have to validate the image resolution and give them a message saying 'Only 1280x720 size images are allowed' or simply i have to convert the image to be upload to 1280x720 size and save in the database. If someone could give the solution for the above problem that would be very much appreciated.
Thanks,
Pramod SR

1. You need to resample.
2. You can automate the process.
1.
Open one of the images.
Go to Image > Image Size
Set the units to Percent (100)
Change the resolution to 300 ppi (not cm!)
Make sure Resample is checked
2. automation
Test the above steps to make sure it works.
Record the steps as an action.
Make a droplet from the action.
Drag the folder with the images to the droplet.

Calibrating image resolution in CS5-CS6

I am teaching a class to create a courtroom display. I have a ppt from the FBI Lab that told me to take two fingerprints, calibrate the image resolution and find a common denominator before i can proceed. I am new to Photoshop and am not sure where i calibrate image resolution or how.

Thank you for responding. Someone from Foray contacted me and explained what to do. They want the image size of two photographs to be as close as possible to the same. If there is disparity, I am to find a number in pixels that is somewhere between the high and low of the two photos…a common denominator. When the photos are resized to that resolution they should fit on top of each other almost identically.

Find images resolution

Hi Forum,
I have tried to get alert for the links if it has 250 or 300 resolution. But if the pdf is placed, the script is replying error message.
"object does not support the property or method actualPPi"
How can i omit the check for PDF and continue to find other images resolution and alert.
var doc = app.activeDocument;
var graphics = doc.allGraphics;
var image, horRes, verRes;
for (var i = 0; i < graphics.length; i++) {
     image = graphics[i];
     if(image.actualPpi[0] ==300 ||
     image.actualPpi[0] ==250){
alert ("images are in 300 & 250 dpi");
thanks in advance forum...

hi -hans-
thanks for the quick reply,
on the flip side of it, it tried to check only for the "Grayscale" images. please see and if you can help on this...
var doc = app.activeDocument;
var graphics = doc.allGraphics;
var image, horRes, verRes;
for (var i = 0; i < graphics.length; i++) {
     image = graphics[i];
     if(image.imageTypeName == 'Grayscale' &&
     image.hasOwnProperty('actualPpi') != false &&
     image.actualPpi[0] ==250){
alert ("images are in 300 & 250 dpi");

Firefox mage quality and resolution was superb when I used XP and Vista. Now that I have Windows 7, however (with the Firefox 3.6.3 version), the image quality and resolution is poor. Please help me!

I am using the Firefox 3.6.3 version with my new Windows 7 operating system. When I used all the previous Firefox versions in my XP and Vista operating systems, image quality and resolution was excellent! However, now that I have upgraded to Windows 7 and Firefox 3.6.3, the image quality and resolution is poor (unacceptable for downloading purposes).
== This happened ==
Every time Firefox opened
== I first activated my new computer and installed the Firefox 3.6.3.

All my images are pixelated in firefox 3.6.3
http://www.dcgdcreative.com
Not only on my site but on most sites I view.
The issue is not solved by resetting the zoom text view (ctrl+0)
The issue is not resolved by starting in safemode with add-ons disabled
The problem seems to only affect .jpeg files and only on Windows 7 on my desktop; as I have viewed several sites using windows XP with my laptop, no issues.
I had the same issue with IE8 and was able to fix the problem with by setting up the compatibility view for all sites. Issue fixed no problems at all. But nothing similar for firefox?
Whats the deal?

Pan and Zoom and Resolution Settings

Okay I am starting a new project and I want to use allot of the Ken Burns, or Pan and Zoom effect. From previous discussions I was advised to scale my photos 2000 x 1500. Given that at what "resolution" to you recommend for the project?

AZ Aurora
If your goal is DVD-VIDEO Standard 4:3 on DVD disc and you have all photos (4320 x 3240 4:3 and 3456 x 2304 3:2), then you do not want any project preset settings described for 16:9.
There are a lot of ways to do this, but stay with NTSC DV Standard as your project preset under the conditions above.
This is one way....
The sizing of your photos can cause problems depending on and in spite of your computer resources....especially if you have about 500 photos. Suggested batch resizing is to 1000 x 750 4:3 for landscape oriented photos. Higher than that, whatever you can get away with without jeopardizing the stability of the project for import, edit, and export.
Set the project preset manually for NTSC DV Standard
        How to is at the end of the following
        http://www.atr935.blogspot.com/2013/04/pe11-accuracy-of-automatic-project.html
Go to Edit Menu/Preferences/General and remove the check mark next to Default Scale to Frame Size
Bring in your photos sized to 1000 x 750 4:3, 2000 x 750 4:3, or the original size 4320 x 3240 4:3 or 3456 x 2304 3:2) - whatever you can get away with. Recommended 1000 x 750 4:3. Remember, no matter how high the resolution of the import, it will be reduced to the sizing of the end product format.
When you drag each to the Timeline, they will appear zoomed in. Ignore that and apply Tools Menu/Pan and Zoom
When you click Done in the Pan and Zoom workspace and you are back in the Editor workspace, scale the Timeline's panned and zoomed image in the
         Edit area monitor as wanted.
Please try this on a mini test run to test the merits of this approach. We can discuss alternatives if necessary.
Thanks.

Still image crop and resolution

Dear All,
I'm creating an H264 1280 x 720 video for Google Maps that incorporates still images and 1280x720 HD video. I've always used 96 dpi for image resolution in the past when I cropped images for standard 720 x 640 video and they looked good. If I crop my still images in Photoshop to 1260 x 720 at 96 dpi, jpeg, will that give me a good still image in the final product? I know that the dpi really doesn't matter unless we're talking about print, but I want to start with a good image resolution. There are many things to learn about all of the new formats! Thanks.
Small Town Gal

Hi SMG,
As Ann said, forget DPI for video, has absolutely no bearing on things. For a 1280x720 video, optimum still size is 1280x720 pixels. If you want to do any zooming/panning to animate the still, then of course a higher resolution will be beneficial.
Thanks

Pan and Zoom/Image Size

I have tried the pan and zoom (Ken Burns Effect) in iPhoto 08 but have been struck by the following problems:
1. With the image slider moved all the way to the left, I cannot move an image left-right/right-left to isolate a particular area for a pan start or finish. I can solely move an image up and down.
2. In order to do any panning, I have to zoom into the image. What this means is that to pan I have to do some zooming, i.e., I have to start with a close up of the subject(s) right from the git-go and starting with a close up eliminates areas of the original image. This is not good.
2. My images in the editor (monitor)are complete large in size, i.e. they take up a good portion of the monitor real estate. I thought that reducing photo resolution/image size to 640x480/72dpi would solve the problem but it didn't. I am still encountering the same limited pan ability.
I build very large and extensive slide shows and I now know the limitations regarding music and sound inherent in iLife but I was not expecting a limitation in image presentation capabilities as well.
Just for comparisons sakes, I have used Photoshop Elements 6 (the Organizer) to build slide shows and have not encountered these problems at all.
At any rate, am I doing something wrong in iPhoto 08?
Thanks in advance for any words of wisdom.

Thank you both for your replies. I will definatley try both suggestions.With the cropping, panning and zooming what i am trying to do is this. On a image in previous version of photo elements you were able to select cropping when making a slide show. What I would do is select the image, select cropping. Then I would select a square or rectangular area where the image would start appearing. Then the next select area (square or rectangular) would be where the image would end up at in that. Its was kind of a start & end point for an image. Then to add to this affect you could fade in to the first "cropping selection"so to speak and then fade out in the second "cropping selection". Then your slide show moves to the next image. All in all the transition between photos are a fade in & out affect, whilst the cropping feature let you pick areas of the photo that you wanted to highlight. You could select a small square or rectangle and the image would fade in "out of focus" but the second selected cropping point would be larger and the image ends up in focus.
I hope this makes sense!!! Anyway Steve I will try your suggestion and see how I go!
Thank you

Help Needed in Zooming and Zooming Out Images in flex

Hi
I am using <mx:Zoom /> component to zoom an image!

Can any one give me the link or code for best zoomin and zoomOut for Images?
Is there any way that I can Zoom Video in flex?

Probably the simplest solution is to use password-based encryption (PBE). See http://java.sun.com/j2se/1.5.0/docs/guide/security/CryptoSpec.html#PBEEx
for an example.
