Saved Image is Very Pixelated on iPhone, Seeking Remedy
Upon saving a two-image original file to my iPhone, the saved new image is very pixelated. Is there a remedy for this? In Photoshop Mix.
We are aware of this issue and hope to get it fixed ASAP. Thanks for your patience!

When I export a photo from lightroom, the image is very pixelated.
When I export a photo from lightroom, the image is very pixelated. This pixelization occurs irrespective of whether I make adjustments in Lightroom. It seems that just placeing the photo into he develope modual without doing anything to it taints the image in such a manner that when it is exported from the develope modual the expot comes out pixelated.
Brett,
The photo i was a panorama knitted in Photoshop from four photos which were approx 3.3 MB each. The knitted pic came out to be 1.10MB. The panorama pic I was trying to refine in Lightroom and export came out to be 70.9 KB and extremly pixilated. Whether I altered it in Lightroom or not didn't matter.
I can't imagine that bringing up the photo in the Develop modual would result in pixilization when it was exported regardless of whether it was altered or not altered.!!
Attached is a copy of the Photoshop saved and Lightroom exported photos before and after. I appreciate your help and interest. The top pic 1.10MB is what was saved on Photoshop. The bottom pic 70.9KB is the unaltered pic exported out of the Develop modual exhiiting the pixelization. -
Iphone 3 GS was not being used for some time. When I charged it for use the screen is not becomeing bright. The images are very dim although i increased the brightness. Pls assist.
Since it's a new machine, contact Apple Service, iMac Service or Apple's Express Lane. Do note that if you have AppleCare's protection plan and you're within 50 miles (80 KM) of an Apple repair station, you're eligible for onsite repair since yours is a desktop machine. That also might apply to newly bought ones inside the first 90 days.
FWIW, IMO, the AppleCare extended plan's the cheapest insurance you can get for your new desktop machine. -
Please help me!--rendering makes the images or video blurry (very pixelated) deteriorates the image Adobe Premier Elements 13 need help! .jpg and mpeg images, but I have never "rendered" before since I got APE 13 about 6 weeks ago. I am desperate for assistance!
That's going to be a ridiculous waste of money and energy.
First of all, the current ATI drivers don't support multiple GPUs, so at the moment even a single 4870X2 would be only a 'normal' 4870 (which is quite a speed beast already). GFX drivers evolve rapidly, so things might look different next month, but when it comes to Linux and hardware there's one Golden Rule: stay away from the newest stuff and wait for proper support to get coded.
I also wonder what power supply could possibly cope with the differences between idle and full load; that's way beyond 400W. But then, I'm one of those "quiet&green" types where >100W idle is already a bit much.
I kind of understand that you want to get it done and not worry about hardware for the next 10 years or so, but that's simply not how the hardware world works and never did. At least not for the average consumer. -
Hello all,
I was just wondering if other people have noticed a drop in quality for saved images. Anything I save from Safari or Mail looks terrible once it gets to Photos - blurry and pixelated.
Not sure if there's a fix or not yet.Update: Oct.5th
For those of you still in the dark about this issue, I discovered it's not a hardware issue as much as an OS one.
I noticed a problem with saving JPG images from either an e-mail attachment or via Safari from my iPod Touch 2nd Gen. The image in the Saved Images folder will render as a pixelated image when you preview it. BUT, when you download the image to your desktop, it appears in its original full size and also sharp in quality. (My example was approximately 1024 x 768 w/ a 300kb size).
I took mine into an Apple store and the Genius Bar tech assistant and I were able to determine that it's because the Touch cannot preview/optimize a downloaded hi-res image with anything that exceeds the 320 x 240 resolution of the iPod. You can test this by saving an image from the web that is around that scale. When you preview it, you should see the image load up very crisp.
He said it's a relatively new problem and that he was hopeful the next firmware update would fix the issue. He was stumped though as to how come the iPhone was able to save images from the web and preview in crisp detail. This apparently is unique to the new iPod Touches.
Either way, since mine was still under warranty I asked for an exchange and he gladly did the transaction.
When I got home and opened up my new one (which had 2.1.1 firmware already installed) I tried saving a hi-res image and unfortunately, encountered the same issue. So it's definitely an OS issue.
Hope this helps clear up any worries or confusion. -
Line along "bottom" of image when using camera on iPhone 4
Hi all
So I have a brand new iPhone 4 and everything seems fine, except for an issue when taking pictures with the camera, which I have a sneaking suspicion is a hardware fault. I'm hoping not, but I don't hold out much hope...
So when I take pictures, I have a line parallel with the bottom (side with the home button) of the iPhone. This appears both in the preview image when taking a shot, and on the saved image. It does not show when shooting video, but I have noticed the image is zoomed in slightly when shooting video, and the line is not in this.
The line is approximately 1cm away from the edge of the screen. This is not a discoloration, like with the bonding agent, it looks like a line of pixels.
I have taken a picture, but can't see how to upload it on this forum. If it'll help, I'll upload elsewhere and link it.
Thanks in advance for any suggestions.And also when I completely turn my iphone off it doesn't reboot when I hold the power button in and I had to do a soft reset to make it restart but even when I did that it wouldn't reboot and about 1 hour later when I tried it again it did the screen was white with nothing on it apart from a small oval in the middle of the screen showing my lock screen and it took 4 hours for it to sort itself out and then it started flickering :( :( please someone help what can I do??!!

Saving image without bits loss/change
hi there,
I was trying to save an Image (which i created myself with MemoryImageSource, and proper bit manipulation where red bits hold some characters, very important)and then i saved the image to jpeg by by using BufferedImage and com.sun.image.codec pacakage...its very important that when i read back the saved image, the bits the pixels array are the same as they had been created....but i found them changing...though image looks almost similar....can anybody out there help me how can i recover the same bits in Image pixel array or save it properly using some other technique, so that when i read the image the bits are not changed???
helps would be appreciated a lot..and your name would appear in my software's about dialog..that's a deal..plz help...
kushalWhat codec were you using.
You want one that has "lossless" compression.
i.e. GIF, TIFF, TGA, BMP, etc.
JPEG has "lossy compression" although as someone mentioned you may be able to call a method to force it to be lossless. -
What is the maximum size of an image height (in pixels) that supports Muse? I noticed that if the photo is too high, reduce the Muses.
thanksThanks for the explanation, it was very helpful

If you place in Muse - an image with either height or width larger than 2048 pixels - Muse scales the image down proportionately, limiting the larger dimension to 2048.
However, if you want to use the placed image at its original size, you can scale the image up to desired size either by dragging the resizing handles or by entering Height and Width values in the Control Strip on top. After that, go to the Assets panel and locate the image in there, then right click that image in Assets panel and choose "Import Larger Size". That would bring back the lost image information from the original image.
Hope this gives you clarity on what you wanted to know.

JAI - Saved image has black background (unless screen config is True Color)
Hi!
I'm trying to save images using JAI's codecs. Everything is okay if screen config is True Color, but if in 256 colors (or even in 65536 colors) the background of my images looks very dark...
Can you please have a look at the code bellow (and try it with some different screen configs). I'm really stuck with that issue; any suggestion may help...
NOTE:
- I've noticed this problem when using JAI's jpeg codec.
- The problem occurs with both JDK 1.3 and 1.4.
- The problem does not occur (only) if screen config is True Color.
- You must rerun the code after changing screen config.
Thanks for help...

Images with negative pixels value
Consider a simple black (0) and white (255) image composed by 3 vertical bands : the first is white, the second is black and the third is white. Image size is W columns by H lines. Band width is W1, W2, W3 for bands 1, 2 and 3 respectively (W1+W2+W3=W).
Consider now a first order edge detecting operation, for example Sobel for vertical edges :
1 0 -1
2 0 -2
1 0 -1
The corresponding edge image is composed of H identical lines (because the image is only varing horizontally). Each line is 0 everywhere, except on transitions : on column W1, there is a positive value of 4*255 and on collumn W1+W2 there is a negative value of -4*255.
Using the following java source code, we obtain an image which have only the positive (>=0) part of each line :
Image img = (new ImageIcon("bands.png")).getImage();
BufferedImage bimg = toBufferedImage(img); // not part of JDK1.4
ConvolveOp sobel = new ConvolveOp(new Kernel(3,3,new float[]{ 1, 0,-1,2,0,-2,1,0,-1})); // vertical Sobel filter
BufferedImage bimg_cont = sobel.filter(bimg, null);To have an edge image that contains the negative part of edges, we do need a specific image format with specific ColorModel and SampleModel. Ideally, we will need a grayscale image (1 sample/pixel) where all elements can represent values from -4*255 to 4*255. So we need a signed type like DataBuffer.TYPE_SHORT, DataBuffer.TYPE_FLOAT or DataBuffer.TYPE_DOUBLE.
Note : it is possible to apply the filter twice, with a mirrored filter, but time to compute will be also twice the normal computational time (very inefficient).
Now, this is the question : do anyone have a solution to compute a sobel filter (or any other filter type which produces negative values) with a resulting image containing positive and negative values ?The problem is the size of the number you have to work with. You can store values ranging from 0 to 255 (the max index for a byte-sized variable) so the total numbers you can store is 256. However, if you want to go from -255 to 255, thats about 512 values, which is twice the size of your max. You would need one more bit on that variable to do that. You could make the far left variable be the positive or negative sign (know as a signed variable) which is how computers do it anyway. The only drawback is it will only range from -127 to 127, which is half as much detail.

hi
I can't close the saving image after i created it. It becomes read only and i get error unless i exit from application when i want to create it again i think it remains open.
Would you help me how i can solve problem?

Hi,
Here is a small example that does the same thing as your code i believe and will overwrite the opened image with the watermarked image. Perhaps you can arrange your code to follow these steps.
Imports System.Drawing.Imaging
Imports System.IO
Public Class Form1
Private Img As Bitmap
Private wmFont As New Font("Verdana", 32, FontStyle.Bold, GraphicsUnit.Pixel)
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Using ofd As New OpenFileDialog
ofd.Filter = "Image Files|*.jpg;*.png;*.gif;*.bmp;|All Files (*.*)|*.*"
If ofd.ShowDialog = Windows.Forms.DialogResult.OK Then
Dim frmt As ImageFormat
If Img IsNot Nothing Then Img.Dispose()
Using i As New Bitmap(ofd.FileName)
frmt = i.RawFormat
Using g As Graphics = Graphics.FromImage(i)
Using sb As New SolidBrush(Color.FromArgb(100, 0, 0, 0))
g.DrawString(TextBox2.Text, wmFont, sb, New Point(10, 30))
End Using
End Using
Img = New Bitmap(i)
End Using
Img.Save(ofd.FileName, frmt)
If PictureBox1.Image IsNot Nothing Then PictureBox1.Image.Dispose()
PictureBox1.Image = Img
End If
End Using
End Sub

Fujifilm RAF conversion to Adobe DNG images become "square pixel"? Any Idea?
I'am using Adobe DNG 8.3.0 on MacOS 10.6.8 to convert fujifilm XE2 RAF file to DNG, thus i can keep my RAW file and edit in LR, but the converted images show very obvious "square pixel"? what wrong? or the Adobe DNG not fully support Fujifilm latest RAF file yet?
Here is the sample of what i mean "square netted pixel":Somewhere in the LR 4 series Adobe changed/improved how RAFs are converted. I think you’re using a really old LR without having set your DNG Compatibility options to old enough—something older than the default of ACR 7.1.
The pattern you’re seeing is from the old LR that expects the DNG Converter to have filled in all the extra pixels whereas the DNG Converter is using a new compatibility mode that tells it that LR can handle filling in the pixels itself. -

Thanks.I am having the identical error. I have an iPhone 4 and 2 macs, the phone is managed from an old G5 PowerMac and images are saved from it to Aperture for photos and videos go to iPhoto 11. The Mac is running 10.5.8. I last appear to have downloaded movies from iPhone4 to mac in December , the oldest video being 10 Dec 2010.
This week I was going to back up a handful of images on the phone but after connecting it to the mac, something that happens several times a week to sync to itunes for app updates etc I found it did not list for import options in iPhoto nor in Aperture. I looked at Image Capture and that tells me no device is connected.
I have no problems taking images off the phone using a MBP which has 10.6 and Image Capture recognises the phone.
I have tried the following after reading through all the discussions on the topic of which there appear to be many with this problem.
Restore the iphone then update settings from archive. - did nothing
Closed apps reconnected iPhone started apps... - did nothing
Switched phone off then on then connected to mac then opened apps - nothing
This Mac seems happy to communicate t othe phone though iTunes but appears to have lost the way when it comes to getting images off the iPhone. Any help keenly appreciated.

Exported files appear very pixelated
Hi,
Today I tried exporting some photos from iPhoto using both the File > Export command as well as using the "Mail" toolbar button to export photos to Apple Mail. I set the export option to use the highest quality JPG but to reduce the file size to a "medium" setting.
The resulting file, for every photo that I exported, was very pixelated and the overall quality looked very poor. Even with the photo zoomed at 100%, I could easily see pixels.
I tried doing a similar photo size reduction in Photoshop and the final files look great. I was hoping to use iPhoto for quick and easy exports when I want to reduce the file size (such as for e-mail) but am not having luck with the pixelation.
Any advice?Terence:
If your pixel count was the same as Neil's, or very close due to the different aspect ratio, the the dpi value is of no consequent. It only means that if printed at that value, your print would be 2.5 times smaller than Neil's.
I exported a 2625 x 1969 pixel image with the max quality and medium size. Upon opening in Photoshop it read 640 x 480 but with a dpi of 656.25 dpi. The print size was 0.975 x 0.731 inches. The total pixels were the same as yours. I then exported a 1600 x 1200 file at medium and got a 180 dpi reading in PS. Same 640 x 480 pixels. Don't know why PS handles them differently.
Neil:
Have you, in the past, been able to export the medium size and have it acceptable? Is this just since iPhoto 08? Try deleting the iPhoto preference file, com.apple.iPhoto.plist, that resides in your User/Library/Preferences folder. See if that will help.
Do you Twango?
TIP: For insurance against the iPhoto database corruption that many users have experienced I recommend making a backup copy of the Library6.iPhoto database file and keep it current. If problems crop up where iPhoto suddenly can't see any photos or thinks there are no photos in the library, replacing the working Library6.iPhoto file with the backup will often get the library back. By keeping it current I mean backup after each import and/or any serious editing or work on books, slideshows, calendars, cards, etc. That insures that if a problem pops up and you do need to replace the database file, you'll retain all those efforts. It doesn't take long to make the backup and it's good insurance.
I've written an Automator workflow application (requires Tiger), iPhoto dB File Backup, that will copy the selected Library6.iPhoto file from your iPhoto Library folder to the Pictures folder, replacing any previous version of it. It's compatible with iPhoto 08 libraries. You can download it at Toad's Cellar. Be sure to read the Read Me pdf file. -
Why does adobe camera raw keep saving images with the incorrect white balance?
I am having an issue when I edit images. here is the scenerio:
I choose 50 Raw files and open them in Camera Raw.
I edit each individually - many of them have different white balances.
Once I have each image how I want them, I select all and click done.
Sometimes all the edits are saved correctly, but very often all the changes are saved correctly except white balance. The program seems to take the white balance from one image and applies it to all the images.
Why??? Very frustrating to have to go back and individually edit all the white balances again.
Thanks!It seems to not happen if I slow down a few seconds before I click select all and then done.
That should not be the problem, once you changed settings and hitting done they all should be applied immediately. It even is not needed to first select all, that is only needed when you need to open or save the files.
But I still don't know why it would only change the white balance in every shot and not everything.
If it happens again could you first in Bridge select one of the none changed files and with right mouse click menu choose select purge cache for selection?
And can you provide more details about system version, app versions and file types?
