Lightroom :: How To Adjust DPI Of Photos From 300dpi To 72dpi
Jan 27, 2012
I'm new to Lightroom so I'm used to being able to simply adjust the dpi of my photos from 300 to 72 (or whatever I need it to be). I can't seem to locate a similar feature in Lightroom. Am I missing something here? How can I change my large 300dpi files into smaller 72dpi?
I have 72dpi image at 18in. I need to go to print. Should I resize to 300dpi at around 4in or just scale down the image? It will go on a business card so I really have enough pixels because it's not very big, just not sure best resize method.
In development mode, any adjustments I make on the sliders on the right have no effect to the picture. Sometimes the picture greys out and I have to try and click on a different picture below for it to show up again. The grey screen comes up if I try and crop and image as well. It feels like it's not letting me make any adjustment to the layer.
It was working fine a month ago. Had a client ask for a picture so started up LR4 and experienced the above problem.I have tried the following.
1. Created new catalogue, import new images. Still can't edit the pictures. Moving the sliders around and has no effect to the picture.
2. Unistalled LR4 and Reinstalled LR4 but still no change.
I get artifacts when I lighten (dark specks) or darken (white specks) when I use the adjustment brush to adjust exposure on my photos. It would seem to be a big enough bug to get noticed and promptly fixed, unless I am doing something wrong.
have never discovered an answer to this one. currently using LR4 and have previously used LR2 and 3 with the same issue.
my PP workflow is essensially for the web, so I save images at 72ppi for web viewing and yet when I create a web gallery with LR it converts each image to a print resolution of 240dpi.
that's right. changes from ppi to dpi. go figure.
even if ppi (points per inch) is exactly the same as dpi (dots per inch), why the heck is LR making the change and how can I prevent that change from occuring?
I've successfully merged a sequence of photos taken along the shoreline of Yellowstone Lake using the Photoshop Elements 11 Photomerge Panorama facility. Alignment is perfect but the sky has gone wrong at one or two boundaries.
The sky is there in both the adjoining photos and I'm sure I could do a better job than Elements if I could adjust the mask boundaries and get rid of the existing smudged area, but I can't find out how to do that.
Not sure if this can be done, i have a web development project to start but have been given a lot of PSD files. Normally this would be ok as i would just bounce them to HTML. The problem i have is they are all set to 300dpi. Is there a quick way to convert them to 72dpi? I don't like the idea of have to convert each layer.
I'm trying to open an Illustrator document in Photoshop. It will only open at 72dpi, but I want it to be actual size, at 300dpi. How can I change this?
I just started a new job and they gave me a new Macbook Pro with Retina. I'm accustomed to designing all of my website mockups at 72dpi, but when I open any of their already designed files, they're super small on the Retina screen. I have to plug in a non-retina external monitor just to work with the files.
What can I do to work on the much more beautiful Retina screen? For new files moving forward, should I be setting up my documents at twice the resolution or size?
it seems to only be doing this on 50 x 0 in 72dpi unnamed (not given an extension yet) pictures!!! every time I have a picture of that size and I bring down ANY menu (such as 'edit') it causes Gimp to be unstable and freeze and I lose EVERYTHING in ALL pictures I have up after closing the nonresponsive process!
I was instructed on a video tutorial to be sure to turn off anti-aliasing on this web design/template I am making in Photoshop as they did. But all my text is really bitmapped and on the video it is not bit mapped at all. There is no way to email them to ask so I did some research on my own.
I am on a windows 7 system running Photoshop CS4. My file is an RGB 32 bit, 72dpi 900 x 1000 pixels - pixel aspect ratio is set on square pixels and somewhere I read to turn off the fractional widths in the Character panel which I did but my text is very bitmapped. I don't understand why I would turn off anti-aliasing for such a low resolution file for the web - and why the video tutorial shows their type is absolutely fine.
I have PhotoShop 4, unfortunately. When I saved my pictures at 300 dpi inRGB and imported them into a PDF program called Serif, Serif said they were 175 dpi. I saved them in CMYK in PSD and Serif said they were 200 dpi. I want to print the artwork in a book and would like to send them to the printer as 300 dpi.
In Photoshop, you can set the size of the eyedropper to sample a single pixel, 3x3 average of 9 pixels, 5x5, 11x11, etc. It can make a big difference when sampling a single pixel as opposed to the average of a larger area.
Can the sample size be set in LightRoom?
If not, what is the sample size in LR when you run your cursor over the image? Does this vary depending on the displayed magnification of the image?
In the Print Adjustment panel of the Print module, what do the numbers, which go from -100 to +100 really mean?Exposure slider in the Develop Module, which are, I believe, fractions of an f/stop?
I've been reading online that lightroom has the ability to control sliders in the develop module by simply hovering over the slider and scrolling. However this doesn't appear to be working for me. Whenever I hover over a slider and scroll, Lightroom attempts to scroll the right panel.
My system configuration: Mac OSx mountain lion Lightroom 4 (latest update) tried for raw and JPG files tried using the macbook pro 2 finger scroll, a microsoft USB mouse and a MacAlley USB mouse
is there anything special I need to do to make this work?
Is it possible to adjust the Capture Time by 5:30 or 5:45 hours? These are the Indian and Nepalese timezones. The Edit Capture TimeShift by set number of hours (time zone adjust) only allows adjusting by full hours and not fractions of hours.
It will be great to have this added to the newer versions of Lightroom as 5:30 and 5:45 are, together with other more exotic combinations, valid time zones.
I created a book with 75 or so photos using Lightroom 5.3. Everything is ok and all done - but I forgot that my display is overbright so that I can see things clearly. On single images, I usually increase brightness and contrast in the print module before saving off a single file to print. I don't want to do this to all the 75 images one at a time. is there a way to adjust the brightness/contrast in the book module... kind of in a batch?
If not, what does the print adjustment equal to in the develop module? For example, I have found through testing, that if I go with +67 brightness and +51 contrast in the print module, it compensates any and all photos that I have developed in the develop module with my overbright display.
Why when I print 8.5x11 to PNG at 300dpi (paper size 2550x3300) the actual image dim’s are 34.38”x26.56”? If I print with the paper size at 612x792 (72dpi) the image will be 8.5x11 but look like poop.
how can I print 8.5x11 to PNG at 300dpi and the image dim's be 8.5x11?
im new in .EPS format... i created an AD using photoshop and the magazine company wants me to save the file in DCS2 format @ 300 dpi (.EPS extension), with color composite
but when i save the file, it only gives me 72dpi resolution resolution option...
Have a question regarding the preparation of a TIFF image for printing. I would like to take the image and use it as the background for a printed flyer I want to mass-produce.
Currently the properties of the image are:
pixel dimensions: 1600 × 790 pixels print size: 564.44 × 278.69 millimetres resolution: 72 x 72 ppi colour space: RGB Colour file size: 3.8MB file type: TIFF size in memory: 13.2 MB number of pixels: 1264000 number of layers: 1
I have been told I need to provide an image at least 300 x 300 dpi in order for it to be printed at a decent resolution.
My flyer is going to be around 100mm x 200mm and will be printed on both sides. I will be placing text over the image too. I have the text ready so I just need to work out how to get the background image ready.
My question is, how do I get the image into a format which is acceptable for printing?
I have always used PS to edit my raw images. I am now using elements. I noticed that when I converted all my DNG files to JPS it saved them at 240 dpi is there anyway to change them?
how to adjust the curve of individual RGB channels. I am assuming the LR4 Tone Curve works like the PS Curves dialog with the channel dropdown.
To make adjustments to individual points on the tone curve, choose an option from the Point Curve menu, click the Edit Point Curve button , and do any of the following:
Choose an option from the Channel pop-up menu. You can edit all three channels at once, or choose to edit the Red, Green, or Blue channel individually. When I click the little icon in the lower right corner of the Tone Curve panel, the panel shrinks so that I don't see the Regions sliders. If I click again, they are visible again. I can't find where to select one of the three indvidual channels.
The Help refers to "the Point Curve menu." Where is the Point Curve menu? Is the Point Curve different from the Tone Curve?
If I right-click (Windows) in the curve dialog, the context menu has a Show Info option. I click it on/off and don't see any change or any info. Where should I be looking for info?
I am constructing a photo book with some text boxes. On a couple of the pages the line spacing seems to go haywire and hence the second line partially types over the first line. How do I adjust the line spacing ?
