I take digital images in RAW format, usually quite large, and then open and save the image as a large format Tiff file. At that point, I have to resize the image for the purpose at hand. Here goes...
I normally take the image down to roughly 4x6 inches (I keep the "Constrain Proportions" box checked) and desire a final resolution of 300dpi. Because I'm starting with a much larger image also at 300dpi or higher, this isn't a problem. However, I'm unsure about checking the "resample image" box.
My question is, should I check this box? I'm going to insert my desired resolution dpi regardless, so is it necessary to check the box or should I leave it unchecked? I'm starting to think that the purpose of leaving it checked is to perform roughly the same function as the "constrain proportions" box - to allow the software to automatically resample the image based on the resizing I do. But again, I have a particular resolution in mind and so I'm wondering if it's okay to just uncheck the box and insert my desired resolution. Or, even leave it checked but just go ahead and insert my desired dpi resolution as planned.
To make this clear in my (Holy & Venerable) head once and for all:
The "resampling down" option should be applied when resizing a picture to a smaller size (Thus, I should preferably use "bicubic smoother"?)
Whereas resampling up will give best results when making a picture bigger ("bicubic sharper" for this one?)
Also, what is your experience of these resampling methods in terms of quality loss? I'd assume quality loss will be greater whenever you try to "create pixels out of thin air" as in resizing pics bigger?
What happens to the image when I transform (Ctrl +T) the image regarding to its re-sampling interpolation aspects? By transform I mean make it bigger or smaller.
In the image size dialog you can determine what gonna happened with the pixels when you change the size of an image by check or uncheck the re-samping. But what happens to an image when I commit a transformation operation (Ctrl + T)?
I've tried to figure out a way to do a batch-resampling in photoshopCS2 (Bridge) but I can not figure out how. My books / Helpfunction does not mention it either (as I can see). I've also tried googling.
Is it possible?
I do not want the pixel-size to be reduced before I do the proper croping and stuff on my pictures for web. I need them to go down from 300dpi to 72dpi, then crop them and then resize them to 800x600 (aprox)
I have a large image (21.6 x 14.4in, 51.3MB, and 240ppi) that I need to reduce to approx. 7 x 5in, under 30MB, and 300ppi. First, I resampled the image down to 7 x 4.667in, 5.38MB, and 240ppi. Later, after I realized that I forgot to change the resolution, I resampled the image up by changing the resolution to 300ppi. I was left with a final image that had the following characteristics: 7 x 4.667in / 8.41MB / 300ppi. Since the file size is larger, I'm assuming that Photoshop did a bit of guesswork in order to add information back into the file.
If I would have changed the resolution from 240ppi to 300ppi at the same time that I resampled the image down to 7 x 4.667in, would I have gotten a better image? In other words, should I have done all of the adjustments at the same time?
I can only resize an image using pixels as unit when resampling is turned on. Why can't I resize in pixels without resampling? I can use all the other units but not pixels...
Is cropping to a larger image the same thing as resampling...? I believe I was told it handled the information differently without adding extra pixels... is this true.?
I am a Creative Cloud member, and have downloaded all of the products and they are all up to date currently. The issue I have is, I see all these people using a new resampling setting called "Preserve Details". They go Image ------> Image Size, and then the window pops up. Now their window already looks different then mine. Mine looks like it did in CS4, theirs has an image preview inside the window, plus they have another resampling option available to them. Why doesn't my have this option?
I have tried to upload an image to show you what I mean, but I am unable to upload via my computer, and yes it is the correct size (>450 pxs wide by >500 pixels tall, 131 KB).
Save For Web offers 5 resampling algorithms (the same 5 as in Image Size, ignoring "Bicubic Automatic", of course) for when the output is being resized.
All choices except "Nearest Neighbor" output an identical image (which is different to all results of Image Size). Although the "Bilinear" output contains the same pixels as the output of the 3 bicubics, its file size is slightly different than their shared file size.
Everytime I Resample pictures that are big in size, and resolution, and I reduce the resolution and the size, the end result is always blurry. (doesn't matter if I use Draw or Paint)
- image is 39.4"w by 29.556"h @ 72 DPI, RGB, JPG (when opened in Paint or imported into Draw)
- I want it to be .976"w by .736"h @ 300 DPI ... yes alot smaller
Ultimately, once at the small size, I need to take all artwork (bitmaps, text etc) and make one 300 DPI bitmap to be run on the press.
I have tried ...
- Resampling the original sized image, that is 72 DPI, into 300 DPI and then Resampling the size from there and end up with Blurry (left on Anti-Alias and Maintain aspect ratio)
- Resampling size and DPI, in one step, and end up with Blurry (left on Anti-Alias and Maintain aspect ratio)
- made the image proportionately smaller (now DPI is 2,089) and then Convert into 300 DPI image, and end up with Blurry
This happens only occasionally. I have a file open in PP5. I resample the image -- reduce the physical size from, in this case, 53 inches to 8 inches high, and increase resolution from 72 to 300 dpi, with the resulting file size smaller than the original. I save the file, then import into my layout in Coreldraw. The imported file is back to 72 dpi and the physical size is huge. I reopen the file in PP, resample again, and resave under a new file name. Same problem occurs when I import into Draw. Of course, I can physically shrink the file to 3 inches high and the resulting dpi will be 300.
I have the latest version of CS6 on my Mac, OS X 10.8.x. I have found a bug where Quick Mask is not always activated when you select it. Meaning, you select Quick Mask and the proper pen, color, etc., and it won't paint in the mask (default = red). It also doesn't appear to be actually /doing/ a mask either, so I don't think this is a display/driver issue.
I'm currently looking for techniques to edit unwanted objects out of my pictures without destroying the entire picture. What i mean, currently I am a realtor taking pictures of homes that I am showing. Many times (usually everytime), there is a sign of the home builder advertising who built the home. I am wanting to know how i can edit/crop the sign out of the photograph when i take a frontal picture of the house with the sign in the picture.
I select edit in quick mask mode and start painting away, I switch back to standard mode and hit delete to leave me with the image I want..and all the rest dissapears...as it should. But the image I have left starts to go transparent.
Can anyone help with this as its starting to drive me mad..I have even uninstalled and reinstalled photoshop but I still have the same problem. How can I have the image remain in all its glory and not transparent?
I am fairly new to photoshop and imageready. I saw some tutorials on animation and have one made the one attached.
The question I had was is there a way to make the letters dissolve or do other actions like those on powerpoint. Where the letter slowly fades away or something to that extent.
How do you change the red color of the quick mask to another color. Im editing a photo and the background has a lot of yellow in it. Its hard to tell whats been masked and what hasnt. I would like to change the masking color to black or blue.
I have recently purchased my first Photoshop editing program I am a novice to both As I enjoy my photography I also love playing with the editing side of my hobby, so I recently purchased Photoshop Elents 6 and ditched my old built-in editing program. I have just started playing with changing the background to studio portrait photos, no I am not a pro just a simple amateur, although I am hoping to do some portrait photography as a pastime (I used to dabble a bit in that field with weddings many many years ago). I have been scouring the tutorials on the web for assistance and come across mention of 'Quick mask'. This would be very helpful to me with my photo background changing, but I don't seem to have it in my program Looking into it further, I am wondering if I have purchased the wrong Photoshop program. The mention of 'Quick mask' refers to Photoshop 6, which I thought I had, but can someone explain to me the differences between the various Photoshop programs as I am confused as to why my later version has not got what the earlier Photoshop 4 has.
i can only find the quick selection tool. What i really need is the selection tool that only selects what you want it to and not everything around it. where can i find this?
I'm trying to use the quick selection tool to take part of an image out and combine it with another but when i click to make the first selection a "Could not use the Quick Selection because the result would be too big." message shows up. I havent even made a selection so how would it determine if it's too big? I just don't get it.
After using this tool, the image is left with horizontal bands running throug the entire image from top to bottom. In between the bands the image is clear.
This issue has been around for the last 4 versions at least, Quick Mask stops working, I am getting fed up with having tio reset photoshop to its defaults, because this means that it takes me a good 30 min to reset all of my settings again, and as this has now happened 4 times today, it is costing me money, at least CS3 was a little bit more reliable than CS4, I certainly will not be upgrading our copies of Photoshop.
Has anyone got a simple way to get Quick Mask working again without loosing the other settings from Photoshop...
Or does anyone know why this happens? My system is 4 x Quad Core CPU, running 16Gb RAM and 2 x 8800 Video Cards on x64 Windows XP, so it cannot be down to memory.
I'm running Photoshop CS4 on Vista with 4G RAM. Even when working on a relatively small picture (34M/69M), I get an error when trying to use Quick Select. The message says "could not complete your request because there is not enough memory". I am not running any other applications and I am allowing Photoshop to use 80% of my RAM. I have a 700G scratch disk. What gives?
My PS is starting to get a little out of control and I hope one of you guys can steer me in the right direction with this.
I do quite a bit of stuff in hi rez (300 dpi) switching back and forth between actual pixel view and fit on screen modes. Recently my "fit on screen" mode wants to keep getting bigger and bigger and no longer snaps back to the correct screen size. Does anyone know how I can fix this?
The other question should be pretty simple. I want to change the default blending options. Things like stroke, inner and outter glow color etc.
I must have 'done' something to change how it works because now when I use it, the pixels are not completely selected.
I press the quick mask button and paint the area i want to mask. Then when I have finished, I go back to normal mode. I usually push 'SHIFT' + 'CTRL' + 'I' to invert my selection and then delete everything I didn't mask however, now when I try to invert, I get the message 'No pixels are more than 50% selected'.
I run SC3 on a PC. The other day I did something that has made it so my quick mask selection no longer works but I do not know what it was. What happens is after in go into the quick mask mode (tap the q key) and with the brush color the section I wish to mask; I then tap the q key again to exit the quick mask mode but the marching ants surround the entire photo not my selection. When in the quick mask mode it does show on the title bar that I am in the quick mask mode and when I tap q again that I am going back to normal mode.
