greetings all

I know theres some trick about trying to increase the dimensions of a file. It involves small steps of increase, like 10%, and then i believe, each increase is followed by a slight unsharp mask.
Or something like this…. does anyone have the complete description of this technique?

thanks

Your steps will work, but with limited results. PS (and any other image program) is only able to create pixels out of non-image data, by guessing. Each increase will lead to some degredation of the image. How much is dependent on the interpolation method chosen, and the size of the increase. It will degrade, but might still be acceptable to you and your client. Only trying it will prove if it is OK. Be prepared for loss in image quality and stop when you can no longer tolerate it. Obviously, the best is to capture the image at the highest possible resolution, so you never have to scale up.

How many times have I had a client who said, "oh, 8×10 is ALL we’ll ever want. I don’t want to pay for a 4×5 film shoot (or high-rez RAW), when we’ll NEVER use it big… "? Then the next day, they inform me that they have just bought space in the airport and want to do a 72"x120" backlite mural!!!!!! Happens all the time. :-{

uh, i knew all that, but the method i was looking for, is sort of "the best way to go about doing something you normally should never do"

there’s a specific enlargement that seems to minimize distortion, done in repeated small doses, and then there’s some additional trick along with it…. i cant remember what it is

Open an image you want res up.

Open the Actions palette and select "New Set".

Name it "Creeping Increase" or whatever you like.

Now select New Action and call it "1.5 Increase"

Next go to Image/Size and put a check in "Resample" and "Constrain Proportions"

with Bicubic and change the width drop down to "percent" and enter 110.

Now go to "Image Size" do the same 3 more times.

Then "Stop Recording"

Next "New Action" Name it "2.0 Increase"

Now "Edit/Purge All"

Next select the "1.5 Increase" in the Actions Palette

and press the Play button.

select the "1.5 Increase" again,

press the Play button again.

Stop Recording.

"New Action" Name it 3.0 Increase.

"Edit/Purge All"

Select and play the "2.0 Increase"

Select and play the "1.5 Increase"

Stop Recording.

"New Action" Name it 4.0 Increase.

"Edit/Purge All"

Select and play the "3.0 Increase"

Now "Image Size" 110 percent.

And again "Image Size" 110 percent.

Stop Recording.

Save the Action.

Or go to the Adobe Studio Exchange and search for ‘interpolation’.

Whatever. I still all depends on how much degredation you/your client will accept.

Or go to the Adobe Studio Exchange and search for ‘interpolation’.

And get the answer: "Nothing found, please refine your search and try again"

My mistake, it’s under ‘resize’, could have sworn he had interpolation in the keywords, Adobe may have removed that bit….

FFrank’s Less Loss Resize

I find the bicubic resize method does not provide very good results. I tried several others once (I remember Lanczos, forgot the others), I think Irfanview packs some, and found the results much more acceptable. Haven’t tried that Frank’s Less Loss resize, will give it a go as well. Pjotr

It beats paying someone else for something that does the same job…
