Can someone please explain to me about file sizes and image dimensions. I have to put together a collage which is 165mm high by 258mm wide. If I click file new and choose default resolution (72) then the file size is ok, if I type in 300 dpi the image becomes huge.
If i chosse 300 dpi then the images I was going to use seem tiny on such a vast workspace - Im confused why does the canvas become so large when changing resolution?
I have a created a new PSD that is 8 1/2 x 11.The canvas size is the same 8 1/2 x 11.I want to put a border around the picture (say 1/2 of an inch all around), and put the finished picture in a Picture frame. After it is in the frame, you would be able to see the entire picture plus the border. Q. Should I change (reduce image size) of the PSD to (for this example), 8 x 10 1/2.     Then increase the canvas size to 8 1/2 x 11. After I increased the canvas size, do a Paint Bucket fill with white (to create the White border)? then print the changed size PSD on 8 1/2 x 11 paper so that it will fit into a 8 1/2 x 11 picture frame I realize I could have just created the new PSD to be 8 x 10 1/2 in the first place.
In photoshop 7, I create a graphic. But most of the time the default size of the canvas is bigger than the graphic. How can I "snap," the canvas size to the picture size?
What is the best way to reduce an image's file size (say by 50%) so that someone with limited RAM can work on the file and then when they are done restore the file back to its 100% size for final output--without sacrificing resolution or pixels. File is a layered psd and will eventually be going to print.
>ap alterations. I have collected many (over 100k) screeenshots of census data. In the interest of not using the actual captures (intelectual property restrictions), I have extracted the data alone to a new multi layered file with each address as its own layer. Some have 1 person, some have 200 people.
Can I export each layer to file in such a way that the canvas will not be the 75 inch canvas in the parent image? I needed to use such a large transparent background because population density is very high. Is ther an autodetect feature?
I'm working on a flyer on a 8x11 canvas, but I want all of the elements I'm working to be transferred to a NTSC video film format. I understand how to a open a NTSC (Video Film Canvas), but I do not understand how to convert a canvas that I'm working to that.
I just got CS5.1 at my job. This must be a preference, but when I adjust the Canvas size, it will constrain the image, rather than cropping the canvas. The Anchor in the Canvas Size menu appears outlined (highlighted?) which indicates that this is something in preferences that I can adjust.
I am trying to export PDFs of drawings with a high resolution image covering almost an entire A1. I realize of course that the file will be very large but it is much larger than I feel it should, and there are also some discrepancies.
The original image is around 100 MB, but only about half is visible in the viewport, so the PDF should be around 50 MB if there is no compression (only negligible amounts of text and lines besides the image), however if I plot it to a PDF using Adobe PDF, setting the resolution to 300 dpi and medium JPEG compression the resulting file is 150 MB. If I choose 72 dpi and low JPEG compression the file looks very bad and compressed but is still around 40 MB in size. This is far too large considering the amount of compression visible in the image, it looks like a 500 KB file tops.
However if I use the DWG to PDF printer instead of the Adobe PDF I can get a very good looking file at around 2,5 MB. Very suitable for printing, but the compression shows if you look up close in the computer (which is a requirement for these files). The odd thing here is that it makes no difference what resolution I set it to, 150 DPI to 1200 DPI creates the same looking file at exactly the same size. I'd like to be able to create a 2,5 MB file to email and a very high quality file for archivation, but not 150 MB large.
Another odd thing is that if I print another file but with the same type of image (a different facade) with 1200 DPI I get a very high quality file of 40 MB, but if I repeat the exact steps and settings for the first file I end up with a 150 MB file. Of course some differences in the image would account for some of this, but not nearly of this magnitude. I deleting everything from the large file and copying in the content from the small file, and successfully printed a 40 MB file again, so there doesn't seem to be some setting or bug in the file I am printing from, rather something in the original file with the image that I have Xref'ed.
How I would go about creating a very high quality file that doesn't bloat up way more than the original image? A 40 MB file is great considering the images are huge, but I can't get this result consistently.
ok it can be supressed on a session basis, but the number of clicks to acheive anything keeps creeping up and I'd rather not see it at all - AFAIK there is no way to suppress it permanently, but the default setting can be increased in the registry
I have my setting at 8000
the registry key is 'ImportSize' in Options > Filters [ verified in designer pro X]
changing registry settings is only for those who know what they are doing and who backup first
is there a function in photoshop cs3 that will reduce the file size of a photo without affecting the physical size of it, i know macromedia fireworks can but thats no help to me unfortunately...
Why is the image on the screen small the the actual file size. As an example I have an image thats 5.7x5.7 @72DPI. My canvas says 100% but the image on screen is about 3x3.
I was trying to add 5mm around the canvas, when i noticed something strange.
I changed the measurement to cm, then added 1cm to each, Height and Width, then changed the Width measurement to mm (which changed both displays to mm) but only one of the setting changed to mm; the height still had the same value it had when displayed in cm.
This only happens when both Height and Width are changed.
im currently working on a project that requires a very large canvas. currently, photoshop will not create any canvas with pixel dimentions of over 30k x 30k. the only way i can currently fit my entire image is to drastically lower the image DPI, any way to change this limitation photoshop has, or if theres another program I can use to do this?
 When I save a file to jpeg the image size in photoshop remains the same as it was as a tiff file BUT according to the information that comes up in windows properties the file is much smaller (300k vs 2.9mg).  Can you advise me which is the correct file size?  If the correct size is the one showing in windows (300K) does mean that the file compressed in JPG and lost a lot of information?
 and if this is the case how can I prevent that from happening and still save the file as a JPG?  [ I would like the image to remain the size photoshop shows it to be] . Thank you very much.
I am trying to open a new document to make a design that will be printed.Since it will be printed, I set my resolution to 300 ppi.I need my canvas size to be 6.5" by 3.625", but the canvas size automatically sets itself to 6.5" by 3.627", and I can't change it. Â I don't have this problem at lower resolutions
I have designed a billboard and used various photos. Due to changes in the positions of the layers, I ended up with a canvas bigger than the photo. So I need to remove the extra canvas. How do I remove the extra canvas? Â I can use the marque tool to copy/cut and paste the photo unto a new file, and hence get rid of the extra canvas. If this is the way forward, is there a precise way to get the marquee tool to the edges of the photo? Is there a function to snap the marquee to the edge of the photo?
I want to change the canvas size, though why is it that when I press the down arrow it adds to the canvas on top, and when I press the up arrow it adds to the canvas on the bottom? It just seems like it should be the other way around.
I have a strange problem when i send my photo i created with photoshop to a company to make a print. In photoshop i create a canvas with the size of 20x30 (300ppi). I put some photo's on it so it fit almost the hole canvas. Than i have a little space for a nice border around it. Finished. Send it to a company and when i receive the photo i check the size of it. It is exactly 20x30, so that is not the problem.
The problem is that i now miss some peace of my border. So if i wanna keep the border i have to send a photo with a canvas size around 19x29.
I need to design my first template using photoshop. the content area of the web site will be 980px ( width ) ..
I like to add border to each side ( left and right ) .. i seen many sits using background image that spans the entire screen and has left and right boarder added to the background , which effectively looks like border on each side of content area.
however, i was not able to figure what would be the best canvas size for this . as each site i looked at , background was set to different size ..
my main content will be in center of the monitor .
im currently working on "stitching" together several high resolution images for work, and have come across a problem with the canvas size. Currently, i cant have my canvas over 30k X 30K pixels, and the only way for me to fit the entire project as one file is to drastically lower my image DPI. is there any way i can change photoshop's canvas limitation?
My picture’s original size was 108.2 MB in tiff. After I developed my photo in Lightroom and exported the new image, the file decrease to 50MB in tiff. Why did Lightroom decrease the file size to more than half the original size? Is there a way to increase the exportation file size to that I may develop a large size print?
A friend took a digital photo with his camera best quality, tiff, and PS showed it had a 72 dpi resolution but a big size: about 70 x 60 cm. (I don't remember the pixels size but it looked high).
I thought the resolution was very low for obtaining a good print but it can be printed with good quality at a 16 x 20 in size. Which is the equivalences between resolution, image size and pixels size? How you convert one mesure to another? Can I forget about resolution and care only about pixels size?
