CS3 and 32-bit (HDR) images

I picked up a book last week about true HDR images - how to make them, how to manipulate them, the pros & cons, all that... The author uses CS3 Extended for his demonstrations. All he really does is use layers, filters, and some of the tweaks in the Image menu - nothing fancy. When I tried my own HDR, merged in Photomatix (basic) and saved, then opened in PS for the fun part, I noticed I didn't have the option of layers at all. I did have the image adjustments and the filters, as I expected. It's just only now occured to me as I'm writing this that the file format (OpenEXR, .exr, using ZIP compression) which I used might not support layers. I can't test that until tonite when I'm home. However, the author does recommend using the .exr or .hdr file formats for the 32-bit images and makes no comment about having to convert to a different file format to manipulate in his CS3 Extended (or at all).
Does anyone here have any experience with the 32-bit mode and "plain vanilla" CS3 - not Extended - and/or those file formats? Is it the file format, or is it a limitation of CS3 basic vs. Extended that I don't have access to layers?
Thanks!

In 32-bit color space you have very limited options in Photoshop. The vast
majority of features aren't available. There is nothing wrong that is just
how it is. Either use the limited tools available or convert the image to
16-bit or 8-bit. HDR technology is still in its infancy. Photoshop with each
version has expanded what you can access in 32-bit mode. But, it is still a
work in progress. Part of the consideration is that a 32-bit image is nearly
twice the size in memory as a 16-bit image and four times the size of an
8-bit. With most computer systems being limited in the amount of memory
available, at least for right now Adobe can allow you to add layers and
stuff that are going to eat up RAM. You are using most of the RAM now just
for opening and basic editing of the 32-bit image as it is.
Once we get in to full 64-bit OSes, lots of memory and real 64-bit
applications things in this area should really change.
BTW the book you mention, cutting and pasting various parts of images to
make one is not a true HDR. A true HDR is one thing and one thing only and
that is a single image made up of several images with different exposures.
Now this may sound like cutting and pasting but it isn't. The end results
look very different. The fact that so many companies and user's choose to
call everything under the sun that evens out exposure in an image an HDR
image doesn't make it so. Taking a single RAW file and adjusting the
exposure to create 4 or 5 different images with what the user considers
different exposure and then using them to create a single image isn't a real
HDR image either. The software from the single oridginal file already saw
the data that was there even if the user couldn't see it. So creating
several images from one is not going to show the software anything that
wasn't there to begin with.

  • Before/after: LR4.1 for 32-bit HDR images - wow!

    I have given the new support in LR4.1 for 32-bit HDR images a try. I'm very impressed.
    Here's an old version (Photomatix I think) of an HDR I shot a few years ago:
    Not so bad, huh?
    Now look what I could do after creating a 32-bit tiff and importing into Lightroom:
    The new defringing is awesome to have. The fringes can become so very visible otherwise when making HDR.
    I've got all the gory details of how I did this on my blog:
    http://davidnaylor.org/blog/2012/05/lightroom-4-32-bit-hdr-editing/
    Anyone else who has given this a spin?

    Actually, I think I may have been wrong there. I believe I actually used
    Photoshop to develop the old version. Even so, I prefer Lightroom's output
    to anything Photomatix would produce.

  • Difference between CS3 and CS4 when placing images, percentage not kept

    There is some kind of difference between CS3 and CS4 when placing images. The images I've dealt with right now were vector images but it might apply to all kinds of images.
    When replacing an existing image, the CS4 behaviour is to let the image fill up the frame. In CS3 the percentage was set to 100% as default (the % you see when selecting the image, not the container).
    Also when replacing an impage in CS4, the "inner" image frame is kept, while in C3, the percentage was kept.
    Is there some kind of placement preferences / settings to let CS4 act the same wat as CS3 did, when placing an image?
    -- Andreas

    Yes, the behavior was changed in CS4 (and many users, like me, prefer the new system).
    If you click and drag a loaded image place cursor the entire image will be be scaled to fit the proportionally drawn frame -- a huge timesaver if you mostly place uncropped art. If you want 100% of the image at 100% scale, just click and release -- same as before, or as before you can pre-draw a frame and place into it and your image will come in cropped at 100% (unless you've changed the fitting options for the frame before placing).

  • Graphics, ImageIO, and 32-bit PNG images with alpha-channels

    I have a series of 32-bit PNG images, all with alpha channels. I'm using ImageIO.read(File) : BufferedImage to read the PNG image into memory.
    When I call graphics.drawImage( image, 0, 0, null ); I see the image drawn, however all semi-transparent pixels have a black background, only 100% transparent pixels in the source image are transparent in the drawn image.
    The Graphics2D instance I'm drawing to is obtained from a BufferStrategy instance (I'm painting onto an AWT Canvas).
    Here's my code:
    Loading the image:
    public static BufferedImage getEntityImage(String nom, String state) {
              if( _entityImages.containsKey(nom) ) return _entityImages.get( nom );
              String path = "Entities\\" + nom + "_" + state + ".png";
              try {
                   BufferedImage image = read( path );
                   if( image != null ) _entityImages.put( nom, image );
                   return image;
              } catch(IOException iex) {
                   iex.printStackTrace();
                   return null;
         private static BufferedImage read(String fileName) throws IOException {
              fileName = Program.contentPath + fileName;
              File file = new File( fileName );
              if( !file.exists() ) return null;
              return ImageIO.read( new File( fileName ) );
         }Using the image:
    Graphics2D g = (Graphics2D)_bs.getDrawGraphics();
    g.setRenderingHint( RenderingHints.KEY_ANTIALIASING , RenderingHints.VALUE_ANTIALIAS_ON);
    public @Override void render(RenderContext r) {
              Point p = r.v.translateWorldPointToViewportPoint( getLoc() );
              int rad = getRadius();
              int x = (int) p.x - (rad / 2);
              int y = (int) p.y - (rad / 2);
              BufferedImage image = Images.getEntityImage( getCls(), "F" );
              r.g.drawImage( image, x, y, null );
         }

    You may want to check on you system and see what ImageReaders are available, it could be ImageIO is just not picking the best one, if not, then you can use getImageReaders to get an iterator of image readers, then choose the more appropriate one.

  • 32 bit HDR Images (Edit in) problems

    I'm using Lightroom 4.3 and Photoshop CS5 12.0.4 64x on a 27" iMac with 16GB RAM.
    I have used the 'FILE - PLUG IN EXTRAS - MERGE TO 32BIT HDR' (Photomatix plug in)  command to create a series of HDR images, which I have subsequently tone mapped in Lightroom.
    Now I want to merge the resulting .tif files in to a panorama, I have tried 'PHOTO - EDIT IN - MERGE TO PANORAMA IN PHOTOSHOP' and 'PHOTO-EDIT IN- OPEN AS LAYERS IN PHOTOSHOP' but neither work.
    Lightroom appears to start the process as I get the RAW 7.3 Warning box, I click 'OK' and then the Photomerge dialogue box opens in Photoshop with my .tif files selected. I again click OK but nothing happens.
    I have tried closing down and restarting both Lightroom and Photoshop, I have rebooted my iMac but still nothing.
    Can anyone offer me any advice or assistance please?

    ...well I suppose Adobe have to try and keep the money rolling in somehow
    That is correct, and I like your attitude .
    People who pay thousands of dollars on hardware should not complain too much about hundreds of dollars in software. Complex software takes a huge amount of time to develop and maintain - companies that produce it must get paid for it... - it ain't charity work... profit margin is very thin, not fat (has to be that way to remain competitive). Adobe makes good money by selling a lot of copies, but rest assured: they could not price things much less or accept less income in one place without getting more in another - otherwise they'd go out of business.
    Movie and sports stars have fat profit margins - not software companies...

  • Open previously created 32-bit HDR image in HDR Pro

    It seems to me that it would be nice to be able to open previously-created 32-bit HDR files back in HDR Pro. I usually create a number of radiance files, which I can then process in different manners for different purposes. Photomatix and all other HDR proggies allow us to reopen a 32-bit file in HDR mode, why not CS5? It is a waste of time and effort to merge files every time I want to reprocess an HDR file to 16 bit.

    Ah! My apologies. I didn't realize that the toning tools would come up (nor is it mentioned in the Adobe knowledgebase page I read on the subject of converting to 16/8 bit). I guess it should have been obvious, though, that there would need to be some control over how to map the tones. Actually, this appears to be the much better way to work with HDR tonemapping in CS5, since you have a real 100% preview, which is, sadly, lacking in the "real" HDR workspace. Great to have found this out.
    Thanks,
    Toby

  • Exposure adjustment layer for 32 bit HDR images

    I know I can adjust exposure in Camera Raw. I can use the adjustment brush to make local exposure adjustments in ACR too. Is it possible to make exposure adjustments to 32 bit images in Photoshop? My attempts at using the exposure adjustment layer weren't successful. Although I'm told "exposure" was designed for 32bit, the adjustment layer doesn't seem to be to access and manipulate any of the exposure data thats I know is in the file, but is not visible. It would be should be so useful, but from what I gather the exposure adjustment is totally useless for 32 bit images. Are I doing something wrong? 

    Thanks for the reply. I'm struggling to explain so i'll try and illustrate instead. Basically the Exposure adjustment layer does not work on the 32 bit file in the same way that ACR does. ACR changes exposure in the predictable way it should (like a raw file). The Exposure adjustment layer in photoshop doesn't work the same way. Or at all?

  • Ugly banding in sky (32-bit HDR)

    I've seen this a few times now, and decided to ask if anyone else has come across it.
    When developing 32-bit HDR images in Lightroom (merged in Photoshop) I sometimes get these discoloured bands across the sky. (Top left corner.)
    I tried to see if any of the sliders (clarity/shadows/highlights/etc) caused these coloured bands, but they are there even if I reset everything and just lower the exposure to get the colour back in the sky:
    For comparison, here is the -3 EV exposure which was part of the (three-frame) HDR. As you can('t) see, there is no banding going on here:

    Canon only offers this capability to pros shooting 1 series bodies, but you can still shoot six images almost as fast with other bodies like your 7D.
    Adjust all the camera settings normally used for HDR shoots. Next set Exposure Comp./AEB for ±2 EV exposure bracketing, shift it -3 EV (-5, -3, -1) and save to Camera User Setting C1. Next shift the ±2 EV bracket to +3 EV (+1, +3, +5) and save to custom function C2. Shoot the first bracket with Camera User setting C1, select C2 and shoot the second bracket. You will have six 2 EV spaced exposures spanning 10 EV (-5, -3, -1, +1, +3, +5) from which you can select the best three, five, or even all seven for the HDR merge.
    You could also use a ±1 1/3 EV bracket, which will give you six images spanning  6 2/3 EV. This is more than the 6 EV range you're using now and with less than 1/2 the EV spacing. You can select the best five images based on the scene exposure, or use all six.
    This of course assumes you don't need the two custom functions for other purposes and are using a tripod. I use a Canon RC-6 remote to help prevent tripod shake. You must set the camera's drive mode to 10 sec. or 2 sec Timer/Remote Control and set the RC-6 remote switch to the lower setting ( not 2 sec. delay). Canon's documentation on remote usage isn't very detailed so it took me a while to figure this out.  This also works best when shooting tripod mounted without the remote, since the 2 sec. delay lets the tripod settle after pushing the shutter button with your finger.
    There are more costly alternatives like the 'Promote' remote controller or running tethered with a laptop.

  • Why do 16 bit greyscale images look significantly worse than 32 bit?

    Howdy,
    I am trying to display a greyscale image from a camera. Parts of the program are written by someone else, and the image comes in as a U16 array. I am using IMAQ create and IMAQ arraytoimage. The image displays perfectly if I use the 'float' inputs on the above to sub vi's, but if I use 16 bit or 8 bit, the image quality is terrible. I would like to be able to display the image as 16bit.
    If I save the 16 bit image, and reopen it with another program, it's still just as bad. I have also tried converting the array to I16, and U8, but it makes no difference to the image quality.
    From what I understand, there should be very little visible difference between 8, 16 and 32 bit greyscale images. Does anyone have any ideas where the problem might be? my next guess is the camera settings, but I'd love it to be something in my code..
    Cheers,
    Andy

    Andy,
    Thank you for contacting National Instruments.  The key thing to note is that the image data type that LabVIEW uses is a signed interpretation so you need to do some more conversion to get an Unsigned 16-bit array to display properly as an NI-IMAQ image.  Refer to the Knowledge Base: 16-bit Images in NI-Vision for more information on how to do this.  Thanks and have a great day.

  • HDR Images and Aperture Workflow?

    Hey folks, I'm starting to get my hands dirty with HDR images, and am having some difficulty with the seemingly high (at least for me) learning curve in getting going.
    I'm wondering if anyone here who has experience with HDR can summarize how they use Aperture in their workflow for creating and working with images to get an HDR result.
    I shoot a series of a shot -3 to +3 (inclusive) in exposure steps which usually nets me about 7 images. Where I seem to get botched results in prepping my images prior to going to Photomatrix, Photoshop CS3 or the not-so-impressive (for me) Hydra HDR plugin.
    Any assistance (or pointers to must-read docs online) are greatly appreciated !

    Hey Magnus, I'm actually trying to limit my processing of any sort to inside Aperture as much as possible. Perhaps I'm a bit spoiled with my need to stick to an aperture-like (RAW) process; I find it frustrating to have to generate duplicate versions of images in external editors (photoshop, hydra etc.)
    I think the main thing for me is to identify a clear path to follow to start generating HDR content I feel right now like each attempt is a stab in the dark

  • CS5 64 bit merging HDR image problem

    Hello,
    I am doing a HDR image lesson (Adobe CS5 Classroom in a Book, page 139) using three .DNG files from the training CD.
    If I use CS5 32 bit all (model's face and background) is ok.
    If I use CS5 64 bit the image has bad background colors and a portion of the model's face is dark red.
    So I a wondering if possibly the DNG was created by CS5 32 bit and cannot be opened and processed in CS5 64 bit HDR?
    Note:
    Each DNG image looks good using CS5-64 File Open.
    I have two jpg if needed to show.

    Has anyone tried this on an installation of Adobe Photoshop CS5 or CS5.1, with an older version of Adobe Camera RAW installed?
    I had this issue reported to me by a faculty member who is attempting to teach this lesson in one of our Mac Labs.  She has taught this lesson in the past without issue, but, recently reported this issue.  We recently upgraded our photography lab's equipment, which included new iMacs, and updates to software installed in the lab, including the CS5.5 Design Premium suite.  I'm able to replicate the issue on all the computers in the photo lab, with the same issue as others described above.  I then went to try to replicate the issue on my personal computer with CS5.5 installed, and, surprisingly, the HDR merge worked successfully.  The only signifigant difference on that computer was that it was running Adobe Camera RAW 6.6, rather than the current 6.7.  I then went ahead and updated the Camera RAW on that computer up to version on 6.7, and the problem doing the merge with these specific files returned as it had in the photo lab.
    So perhaps this is a combination of 64bit and Camera RAW 6.7?  I can't get the 32bit workaround to work on the Mac's I'm testing.  Any suggestions would be appreciated.

  • Unable to Open Images in Bridge CS3 and Continuing Icon issues!

    Re: Icon issues in Bridge CS3 and also with Photo Downloader that have never been there before.     
    So, these are the issues.   Just one of the folders that previously would show thumbnails now only shows DNG icons, and none will open in Photoshop to let me work on previous image.    Issue #2  - can't download images with Photo Downloaders - both my wife's Canon G9 only shows CR2 icons, and my Nikon D300 only shows NEF icons - neither of these issues had appeared before or been an issue.  Third issue.  None of my Bridge folders - even those with regular thumbnail immages- will open now - get a message that says words to the effect of Photoshop doesn't recognize this type of file.  Computer is a Mac, with OS 10.5.8
    I recently tried to make more room on HD, so must have taken some critical files/commands out by accident. 
    Thanks for your time and previous  suggestions - still not working.  I'm sure that in trying to correct things have made things even worse- as may be noticed  by the two snapshots I've attached.  The first is one from a library from my user section.  The second library image is from my hard drive.  Hopefully you and others aren't laughing or crying too much over what you see - redundantcy, etc!  All of my energies have focused on taking photos, obviously none to proper setup/use of organizing things on my Mac.  But after the laughing has stopped, any help will be tremendously appreciated - am most anxious to getting back to working with and saving images.

    First of all, if you don't know much about how applications work inside of the OS, its wise to not look in the application folder(s). Deleting anything here can make your apps go haywire. If this happened, then you are best to 1)unregister photoshop, 2) uninstall your entire suite. 3) reinstall the suite and finally 4) reregister photoshop.
    All images/textures/photo's including dng, cr2 and nef files need to be stored in your pictures folder and no where else, unless you're an intermediate user on your OS. In your pictures folder you can create folders for organizing the pictures whether by location, season's, time, or file format.
    Then when you back up you can just drag a copy of the files to another drive including cd's or dvd's.
    This will make sure you don't accidently delete important app files.
    All this said, my OS of choice is Windows, so if anything does not sound right, thats why.
    Hopefully this helps...

    Hi, Tom.
    FYI: You've not stated which of your listed Macs is having the problem. However, the following may help in any case:
    1. Did you install Front Row using the Front Row hack on a Mac that did not ship from the factory with Front Row installed? If so, See my "Uninstalling the Front Row hack" FAQ. This has been known to cause a variety of problems, including the menu bar (Clock, Spotlight) issues you noted.
    2. If you did not install the Front Row Hack, an incompatible or corrupted Startup or Login Item may be partly to blame for the problems with the menu bar. My "Troubleshooting Startup and Login Items" FAQ can help you pin that down if such an item is causing the problem.
    3. As a general check, run the procedure specified in my "Resolving Disk, Permission, and Cache Corruption" FAQ. Perform the steps therein in the order specified.
