View Full Version : Video Tutorial: LW for Print - Camera Resolution

I made a new video tutorial that briefly covers LW11's Print Camera utility for figuring out camera resolution for print. I haven't forgotten about those of you who don't have LW11, so I show some other options for accomplishing the same task. Once the image is rendered, I show how to change the image to 300 PPI/DPI in PhotoShop to satisfy the clients who believe DPI by itself is a meaningful gauge of resolution.

lol well done. And don't be a smart *** like me who tried to make fun of the client by resending the same image with 1000dpi tag, and...ah well, "now it's wrong the other way, come on, can't you get it right?!" ahah.
300dpi, the magic number for the agencies people.
thanks for the tutorial Dana.

One of these days I might try to make a video that tries to explain the whole DPI to resolution relationship to the ordinary man on the street. I have a feeling it'll require props or at least illustrations :D

Client: "We want a 1200px x 1100px image at 300dpi"

Designer: "So you're wanting a 4x3.67 inch image at 300dpi"

Client: "No, it's got to be bigger than that... at least 1200px wide at 300dpi"

Designer: "Sorry, but a 1200px x 1100px render will give you a 4x3.67 inch image printed at 300dpi, and 8x7.33 inches at 150dpi"

Client: "But we need a large 1200px x 1100px image at 300 dpi"

:bangwall:

Good little tut there Dana. The last part, in Photoshop, would only be relevant if you were presenting the client/printer with a PSD.

If people want a nice image size calculator, I use this one:

I just tried saving it as a .tif, and it retained the 300 DPI setting when I brought it back into PhotoShop, so I guess the dpi setting is file-format dependent.

Ok, just to clarify, because this can be really misleading to others. Changing the DPI settings in PS, as per the end of Dana's video, will NOT change the dimensions of the image in pixels (that's why he says NOT to have 'resample image' checked when changing the resolution settings). What it will do is change the document size for the DPI resolution selected. This will then be retained when the image is reopened in PS.

I wonder, it must add some metadata to the image file, so that when it's reopened in PS, it brings in the correct DPI. Because as Dana pointed out, this is the case with PSD, PNG and JPG - so I presume it would be the same for other image formats.

Thanks for the input, Waves of light. It may have been good for me to show what happens when Resample Image is left on and the DPI is changed, but I'm not going to redo the video at this point. :)

I'm trying to get out a new video (tutorial or a render of some kind) every week, but I might take a few weeks off due to work and travel plans.

@Zapper1998, thanks for subscribing :)
