Burning vs. loss of sharpness

When I make a project all photos in my slideshow are good. If I burn it I'll lose sharpness of photos. How to solve that problem?

Hi
A. DVD is as standard (no difference if You use iDVD or Roxio Toast™ or DVD Studio Pro) ONLY interlaced SD-Video and can never be any better.
B. iDVD has a 99 photo / SlideShow limit. I prefer to do mine in iMovie HD6 or FinalCut as they do not have any limit I know of. AND they can handle interlaced SD-Video so that 100% will be delivered to iDVD and to the DVD disk to be.
iMovie'08 to 11 - CAN NOT DO THIS they only delivers every second line - resulting in a severe quality loss.
If in iMovie HD6 - one use Share to iDVD and not use Ken Burns Effect there is a double disaster.
• the file rendered in iMovie and delivered to iDVD is severely pixilated = of no use = VERY BAD
• the original project in iMovie HD6 is harmed and all photos needs to be re-imported and re-edited.
So by just editing and then Save and then CLOSE iMovie and import into iDVD Quality will be 100% of what iDVD can do - and to me very GOOD
If You need better than this and need a disk - then You must reach for Blu-Ray and Roxio Toast™ can do this to standard DVDs (limited to max 20-30 min in HD quality) and if You got a BD-burner and BD-disks to several hours. THESE Disks can not be played on any standard DVD-player but on PlayStation 3.

Loss of sharpness upon image rotation: Aperture vs. other software

I have carefully studied the resulting loss of sharpness upon rotation/straightening of images. This topic does not apply to 90/180 degree rotations.
When any image is rotated (be it JPEG or uncompressed), there will be a slight loss of quality (seen as a loss of sharpness) due to interpolation. The method of interpolation applied will affect the degree of quality degradation.
Simply put, professional applications such as Adobe Photoshop and even Adobe Lightroom use superior interpolation methods when performing rotations (and who knows, perhaps for other transformations/scalings also?!). Apple Aperture, on the other hand, uses an interpolation method that renders a loss of image sharpness on par with inferior consumer-level software such as Google Picasa or iView Media Pro. Yes, folks, here's a clear reason to select Adobe Lightroom over Apple Aperture.
Please take a close look at the comparison yourself:
http://web.mac.com/rishisanyal/iWeb/Homepage/Sharpness.jpg
Make sure you are viewing the image I have posted at 100%, not scaled, in order to clearly see the inferior quality of images rotated with Aperture & Picasa.
Apple needs to address this problem by implementing a better interpolation algorithm with its straighten tool. It is sad that we are using and paying for a 'Professional' application that yields results on par with FREE software such as Google Picasa.
As much as I like Aperture for its other features/integration into Mac OS X, I am switching to Lightroom as of now. Straightening/rotating images is an absolute must, used by every photographer on a daily basis. The loss of image quality, therefore, is unacceptable.
Please post to this thread if you have experienced the same problem or are simply concerned over this. The more people that show concern, hopefully, the more likely Apple is willing to do something about this ASAP.

Surely any rotation (apart from the 90/180/270 ones) is by-definition a smoothing operation ? You have to take the values from adjacent pixels and combine them based on the rotation, then average (or use a point-spread function) them to rescale the values back into range.
Looks to me as though the Adobe products are just applying a sharpen operation immediately after the rotation, whereas Aperture isn't. Or Aperture could be using a simple average of the values, where Adobe is doing a gaussian summation-of-components or something similar.
My guess would be that they "do a quick sharpen", otherwise it would take longer to do the rotate. The only way you'll ever know is if the developers tell you though...

Major Loss of Sharpness iDVD Slide Show

Sorry if this seems like just a re-hash of the "Loss of Saturation" thread, but wow....what a disappointment. Actually I was shocked at the result of my first DVD created in iDVD. The images are so soft I'd be embarrassed to give this to someone to view. I shot the pics at ISO 200 inside with available light with my Canon PowerShot G5 at next to the highest resolution (Superfine 1600X1200), all images saved as JPEG's, no photo editing done. The images are very sharp in iPhoto.
Would shooting at ISO 100, highest resolution, or saving as TIFF or other format result in sharper images in the finished product or is this just the nature of the beast?
I can certainly try it out myself this weekend but was wondering if anyone else found a way to get sharp, well saturated images in an iDVD slide show.
Thanks in advance.
Dale

Dale,
Since nobody else answered your other question, let me weigh in. It doesn't matter what ISO you shot the images at, if they look right in iPhoto or Photoshop or whatever software you're editing (or not editing) in. In theory the image you see in iPhoto (or iMovie or iDVD) should be what your final image looks like when you burn to DVD and play it on your TV. The problem you'll have is getting the saturations to match since your TV is working off an entirely different set of color and saturation settings than your computer. When I'm editing and working through colors for a DVD slideshow presentation I'll actually connect my powerbook to my TV and edit the photos directly on the television, thus giving me the correct colors (even though they usually look like crap on my Mac, they look right on the TV)
Hope that helps a little.

Lightroom 4.1(64bit) loss of sharpness

Hi,
I have converted to jpg some .nef from my D800 with Lightroom 4.1 at max sharpening, 150, with Capture NX 2.3.4 with max sharpening set in picture style settings only and ViewNX2 2.5.1 with max sharpening set in picture style only. Have played with other settings in "details box" of LR4.1, radius, details and masking, but the result is about the same. Please, look at this two photos, converted with CaptureNX 2.3.4 and LR 4.1: at bottom the loss of details is noticeable(the palm, the street lamp). With ViewNX2 have the same result.
Fortunately, it does not happen with all the photos, but happens. Happens in particular with the dark photos and night shots. Please note, that it is not a matter of contrast.

Hi Jeff,
already do it, but unfortunately the result is about the same rather, is the same.
I don't know why other minor software are better in sharpness.
Thanks anyway

ProRes Video in Photoshop - loss of sharpness

Full HD Prores videos are after Photoshop (removing dirt from scanned film) and render back to Full HD Prores less sharp
(best seen at the pointed feathers).
Giving it back as psd or jpeg frames keeps the resolution but changes brightness and gamma.
We also miss Prores HQ.
Who knows help?

Thanks,
image sequences are an option but quite cumbersome because in every case we have to go back to video for broadcast.
The main problem seems to be the AME in Photoshop. Take uncompressed video or image sequences and render it to ProRes or other codecs
you get in Photoshop allways the same loss in resolution. If you take Final Cut for that job you have no loss in quality. We wonder if all Adobe Programs using Media Encoder have this problem.

AVCHD Loss of sharpness

I have been combing the forum looking for an answer. Is it normal to see a lack of sharpness when importing avchd into imovie 09 from a sony. I have tried exporting in loads of different formats and the quality is the same as just after import. I am importing using the full HD size option. It just is not as sharp as i would have hoped. Will FCE be any better?

I was just over at the HiDef Forum and came across others inquiring about this issue. What the posters there said (there were several and they were all consistent with each other) is that iMovie converts AVCHD to another format (some specified AIC). Two things happen when this is done. First, the file size expands ca. 10x, and second there is some loss of video quality. One poster provided a link to an Apple web page that (the poster claimed) acknowledged the file size issue. I did not verify the link to confirm that, though.
Several of them recommended the Sony software provided with the camera running on a PC.

PSE -5, loss in sharpness of pictures when placed in slide show

In PSE-5, when good pictures are transferred from tagged groups to the slide show, there is a significant loss of picture quality despite using "high quality". Is there a way to make the pictures in slide show have the same quality an in the storage areas of Photoshop?

I'm a little confused as to where you tried to delete the slideshow from.
Was it from the actual Project Browser, where all the assets are listed?
Can you try deleting the surplus slideshow from there, and let us know what happens please?

Loss of sharpness

I synchronize photos with itunes and see that the pictures are not sharp, but if I zoom and then back to normal size are very sharp. What is the best method to upload pictures and display them with the original resolution. Should show sharp right away and not having to zoom to get a good sharpness. Apparently iTunes optimizes the photos before uploading to ipad.

Publishing out to SWF or HTML5 causes loss of sharpness

When I publish out to Html5 my project looks blurry, out of focus compared to the .exe or Swf publish. Any advice on this?
CP6 on Windows 7

So, in troubleshooting this, I'm finding that this blurriness is IE-specific (and technically, IE 9), and yes RodWard, resizing definitely does play a part in this.
I'm finding that publishing a file in HTML 5 to a fixed size looks ok. The captions and text are definitely not as sharp as the SWF version, but the images and videos are really close. It's tolerable. The issue I discovered yesterday is that publishing scalable content is where browsers make a big difference. If I publish a project as a SWF file in scalable mode, the images and movies in the project look extremely pixelated, unless you resize the browser window to the same size at which the video or screenshot was originally taken. Publishing the same content in HTML 5 (again, as a scalable project) results in extreme blurriness, but no pixelation. This is only in IE (which is unfortunately the target browser for our intended audience). When the same file is viewed in Chrome, it looks great. The images look more sharp, and readability is greatly improved.
So to address your questions vishhere, yes, this is definitely happening in desktop browsers, and I haven't checked it on any other project, as this is our first project since we upgraded to Captivate 6. All slides are High 24-bit, and no matter what compression settings I use, this issue keeps happening.
Project settings all seem fine, and the fact that output is ok in Chrome leads me to believe that this is really an issue with IE's ability to render scalable content. When viewing the scalable content in IE, it's blurry at all sizes, from a very small browser window to full screen.

Loss of sharpness in transition from camera raw to photoshop

i noticed that when i open a picture in camera raw the tree branches have smooth borders and look real. When i then open the picture on photoshop, the branches then look much more jagged instead of smooth borders. is there some way to avoid this? It doesn't seem right to me.
THanks very much.

Check your Camera Raw preferences. One of the options there is to apply sharpening only to preview images (or all images). If it's set to just preview images, then the sharpening won't be applied when you bring the image into PS.

How to reduce size of a PDF file without loss of sharp graphics

Hi, I'm working in Acrobat Pro X. I have combined a file of graphics, and need to reduce the size. Original graphics were created in PScs6, and saved as .jpg's. What would be the best way to reduce the overall size of the PDF file and still maintain the clarity of the graphics? Advice would be appreciated.

When you are dealing with graphics, you are almost always talking about reducing the resolution or color depth. A lot depends on the graphics themselves. You might check one of the graphics and see what the color depth and resolution are. The 300 dpi setting is fine in most cases, unless you are wanting folks to zoom in. For many applications a color depth of 256 is fine rather than millions of colors. If those are acceptable options, be sure your graphics are set that way. You can try the Optimize to see if you can improve the size and still have adequate resolution (File>Save As>Optimize PDF).

Is there a way to increase exposure without loss of detail/sharpness?.....

I normally use iMovie for most things. I am producing a DVD for the public. The High Definition video I took last week with my Sony HDR-HC1 is just slightly underexposed. I've tried to correct exposure in iMovie, but this results in a loss of sharpness and detail. Would using Final Cut Pro HD provide a way to fix my under-exposure without losing the detail and sharpness of the video? Any help would be appreciated. Thanks.

PowerMac G5 Quad Mac OS X (10.4.8)

I don't know much about iMovie's capabilities here, but I've seen wonderful fixes with the color correction in FCP... I'd think unless your video is REALLY underexposed (as in so dark most of the picture is black), you'd get fine results with FCP.

Photo sharpness in Acrobat

Saving Photoshop files as PDFs and later combining them into a single PDF using the Acrobat Combine Files Into a Single PDF causes a loss of image sharpness.
Contrary, opening the Photoshop PDF file in Acrobat and using the Add Pages menu option produces no loss of sharpness.
Why does the Combine Files Into a Single PDF option degrades the photo quality and what is this option meant for?

Did you check the conversion settings when you used the combine function. In the version of Acrobat on this machine (AA8), there are three resolution options.

Straighten tool reduces image sharpness

Has anyone else found that when rotating JPEG images using the straighten tool, there is a loss in sharpness in the rotated image? I am using the straighten tool on a 100% zoomed image, so this isn't an artifact of cropping/resizing. Even at 100% zoom, any image that has been 'straightened' appears softer compared to the master (when I'm clicking 'M' to switch back and forth between master and straightened image).
This does NOT have something to do with how Aperture simply DISPLAYS 'straightened' images in real time, because if you open the straightened image in an external editor (Photoshop), it STILL appears soft! However, if you perform the same rotation on the original image withing Photoshop, the image remains sharp!
Aperture's rotation/straighten algorithm is seriously flawed?!

This is true. Rotation DOES result in loss of sharpness because of interpolation, etc.
HOWEVER, the loss in sharpness under Aperture is UNACCEPTABLE. The loss of sharpness under Adobe Photoshop, on the other hand, is ACCEPTABLE.
Here is a self-explanatory image showing the UNACCEPTABLE loss of sharpness upon rotation of images under Aperture vs. Photoshop.

Apple, step it up. Or else I want my money back. Aperture, in my eyes, is no longer valid software for a 'professional photographer'.

Straightened or cropped photos lose sharpness

The following phenomenon which annoyed me in iPhoto 08 and is worse in 09. The phenomenon is not processor- or display-dependent -- I see it on both my G5 with 23" cinema display and my 13" MacBook.
I don't currently have RAW capabitlity so the following all refers to JPEG images:
Try this:
1) Find a photo that has a fair bit of sharp fine detail -- architectural stuff is good, like houses with wrought-iron bits, small bricks/tiles/ornaments or similar.
2) Open the image in Edit mode and use the Straighten function to rotate the image a few degrees. You'll see that the image loses some of its sharpness. (Alternatively, crop the photo a bit -- same result.)
3) Click the Done button or move to the next photo to record the Step 2 change permanently.
4) At this point you can directly reopen the image, or you can quit and restart iPhoto, or even quit and restart the Mac, and then reopen it. You'll see that the image is still slightly unsharp.
5) Now grab the picture size slider and move it just fractionally (the smallest amount you can) to the right. After a few seconds, more or less, you'll see the image regain its former sharpness. Move the slider back to the extreme left again, and once again you have the less-than-sharp image.
Having discovered this in iPhoto 08, I had developed a solution, which was to open the image in Photoshop, make a tiny inconsequential edit -- just enough to get Photoshop to rewrite the image when you resaved it (as a JPEG to replace the iPhoto original). Having done this, the image would then open in iPhoto in its correctly sharp form.
The bad news is that in iPhoto 09, this solution doesn't work!
I'm not sure what to do at this stage. It looks as though I may simply revert to iPhoto 08 --- I don't want to have to move the size slider every time I look at a photo to see the "unfuzzy" version.

I have the same problem; the only way is to export photos straightened and re-import them again into the library. But i found some cases in which this workaround doesn't work at all: in some cases photos remain "out of focus"; this is only a view problem in i-photo, because viewing them in an external editor no loss of sharpness is found. This is very strange because in this case photos have not an associated modification that has to be applied on them; in this case photos are like originals but they look out of focus too. I tried to reload the thumbnails reloading library (with command+option buttons while clicking on iphoto icon) but nothing changed. Is there a way to have photos look as they are?
I think this is a big problem, since i-photo is a tool which main functionality is to view photos.
