In order to save hard-drive disk space I want/need to start compressing my Photoshop files. The Tiff-LZW or Tiff-ZIP compressions seems like a great lossless format alternative with apparent significant compression. Is anyone aware whether there is truly no loss of file information with these formats, or does some minimal degradation occur? Any thoughts on JPEG2000 lossless compression?
View 5 RepliesI am archiving numerous historic photographs by scanning the originals as high-resolution TIFF files. I need to rotate the scanned images slightly in Photoshop for presentation/archiving purposes but I am worried about losing some image quality.
To maintain loss less images, is it necessary to open my TIFF images as "Smart Objects" before rotating them? If so, this increases my file size many-fold on saving. Is there a way to maintain the approximate size of my original TIFF file? I am working in Photoshop CS4, Windows 7 64-bit.
Since a couple of days when I export tiff files to jpeg the exported image looks darker. If I reimport it the histogram is evidently changed.
It looks like something messed up in preferences but I didn't make any changes (at least I didn't do it purposely).
I upgraded to the 4.4 version after this happened but nothing changed.
Till X3 Photo-Paint opened and saved transparent PNGs as a seperate image with attached mask.Example:I have an image and load a B/W mask into it.
When I save this as PNG and reload it in X3, Photo-Paint displays again exactly what I have just saved:
However when I open this same PNG in X6, the image and mask get merged into a single object:
It's in effect doing automatically a "create object from selection" function and discards then the background.Why? I can't work with the full background image anymore, because the transparent parts are missing, and the mask is also gone. Is there no way to open the full PNG, without any merging and deleting of masks, just the way X3 was doing it?Also, the only way to save a transparent PNG in X6 is to check "save only selected objects"? When I don't check this, but still check "transparency" in the PNG export dialogue, then the mask won't be saved nonetheless.
I have an aerial image in TIFF format.Can I get DEM information from this format? If yes, what should I do?
View 3 Replies View RelatedI am cleaning up the Hard Drive on my Mac G4. My scanned images are taking a great portion of the 80 Gig drive. I finished clearing my external drive by removing nearly 60 gigs of images by storing them on DVD. I will do the same for the Mac drive.
My trouble is that all my images are stored in TIFF format which takes up enormous space no matter the storage. Since I output images in various sizes, mainly prints, to 30 x 40 inches, I need a master image archived in the best format for such. However, I do not want to fill my drives, or DVD, with large files. Code:
I am a AutoCad drafter for telecommunications and I have utility pole points (long/lats)
I can insert the poles via long/lat and all is great, my issue is I would like more information in those points.
For example, pole number, class, HOA, Make Ready. Currently I create a survey data store and import ASCII Points using PNE(comma delimited)
So with my Excel file (this is where I get my pole information from) I get a point/northing/easting to enter into the formatting section.
I would like to add more information to these individual points, like ploe number, class, HOA...
If I view the point table I see that there are a lot of other columns, can I use them or customize them? is there a quick tutorial on this issue?
I am using PSE 12 as an external editor for Aperture. When I ask to use an external photo editor, Aperture creates a .tiff file in my Aperture folder, launches PSE 12 and tells it to edit that .tiff file. This all works great. When I am done editing in PSE 12, I ask it to save the file and it saves it back to the original Aperture folder with a .tif extension. I can instead say "save as" and then it suggests the file name with a .tif extension. When I correct the extension to .tiff it warns me that I'm going to overwrite the file (exactly what I want!). I say yes and then I find out that PSE did not overwrite the file, but wrote it as a .tif file anyway. I have to go to the folder, delete the .tiff file and rename the .tif file to .tiff and then everything is fine - but what a hassle.
View 3 Replies View RelatedI have recently installed Photoshop CS3 on a newer PC which runs Windows 7 Home Premium, after the programme was locked on a PC running Vista which died on me and which I have just had repaired. However since installing the programme, every time I turn my PC off and then on again next morning, I have lost the internet.
I have been getting around the problem by running the HP network check and the automatic repair that it performs is to "reset the Realtek PCIe FE Family Controller Adapter". However this only works until the PC is turned off again and then I have to do the whole process again. Is there a way to fix this problem permanently? I was hoping there would be an update from Adobe that might sort the problem, but Adobe don't seem to be able to work with that as they say the programme is too old and don't have online support for this.
I have followed everything that is suggested by HP i.e. rebooting the modem and router.
If I reset the PC to before the programme was installed the problem goes away. When I reinstall the problem comes back. Its definitely to do with the Photoshop programme, but I don't understand why.
there is Old picture in sizs 5" x 7".
I want to print this picture from lab of size 16" x 20".
Please can anybody tell me How I convert this picture in to biger size without any lose of resolution and Quality.
I convert the original picture in to TIF.
then Go to Image size increase the Percentage by 100 to 125.
and Again save this file into Tif with Name A1.
Then Again Open A1 do same size change 100% to 125% and save this by name A2.tif.
continue...
This is right way or any method.
why I suddenly lose all my loaded presets and also preferences (like zooming with the mouse wheel). I don't lose the presets altogether, but I have to go back and reload them again. This doesn't happen all the time, only occasionally and I can't fathom out why.
View 4 Replies View RelatedWhen I take a screenshot and paste it into photoshop I am losing a lot of color. Here I took a rainbow gradient and placed consecutive screenshots side by side.
The first bit is the original, then the first screenshot, then a screenshot of that, and so on.

I created a collage type image in CS3 . It had 4 layers with a tiff size of 60mbs. as a psd file it was about 20mb. when i saved it as a jpeg it shrunk to below 1 mb. I can't print the jpeg larger than larger than a 5 x 7. what am i doing wrong? why would the jpeg shrink so much?
View 2 Replies View RelatedI had an 18MP picture (3456x5184 pixles) and I was trying to fit it into an A1 canvas of a 100 dpi so I used free transformation to scale it down. Later on, I have decided to make the canvas of 150 dpi instead of 100. Would increasing the resolution now make my picture look pixelated on the canvas? I know that the original photo would look alright on a 150 dpi.

Wondering if there is a loss of original full RGB information if changing color mode from RGB to CMYK and back to RGB. I understand that RGB has a wider color gamut and that if changing to CMYK that I will have a narrower color gamut. BUT, I want to know how if Adobe retains full RGB data after changing color mode to CMYK?
In other words, If I change from RGB to CMYK and back to RGB will I have all the original color data that I did with the original image? Does Photoshop "throw out" the full gamut information for RGB when switching to CYMK, so that when I do convert back to RGB, it is jsut looking for the comparable RGB color within the CMYK gamut now?
OR
Does Photoshop "know" the full color information regardless of in RGB or CMYK, but only changes that color information to fit within the CYMK color gamut while "remembering" what it's full color gamut WAS outside of CMYK?
If I do lose full RGB info, what's the best workflow option when using for print in indesign? Keep two seperate Photoshop files, one original RGB and one CMYK? OR just place into InDesign as RGB and change to CMYK when exporting as PDF?
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?

Basically, I saved a copy of of a PSD to a JPG (max quality)
Then I opened the saved JPG and removed a few guide lines and re-saved the file still at max quality.
My questions is, did data loss, or re-compression occur during this "re-save" process? Is the re-saved file now of lower quality than the originally saved JPG?

Windows Explorer and some software bundled with digital cameras [Canon and Panasonic] warn when rotating a picture that there may be loss of image quality. Presumably it must re-compress the jpg image file?
In order to avoid that problem, I have been rotating image files in PS7, since no such warning comes up there.
Is there loss of image quality by rotating or cropping in PS7? I usually save jpg files at quality level 10.
