Help with scaling please

[andy_8039]

Hey folks

This should be an easy one, hopefully 🙂

Im looking for help in scaling to a measurement i have in an image.

I am making mockups showing prints at scale on customers walls, they send me a photo with something in the room i can scale to and give me the measurement. Ie a sofa width.

Could you help me with the easy way to do this, i am pasting the image of the print into the customers photo.

Im using CS6

Muchos appreciated

is this an indesign question?

Photoshop thanks

in the future, to find the best place to post your message, use the list here, https://community.adobe.com/

p.s. i don't think the adobe website, and forums in particular, are easy to navigate, so don't spend a lot of time searching that forum list. do your best and we'll move the post (like this one has already been moved) if it helps you get responses.

Thankyou very much, ill see what i can find, any pointers?

(for photoshop questions, ask in the photoshop forum where i've moved this, and you have a response from @ExUSA .)

Drag a guide to each edge of the known object. Use the Ruler Tool to measure the distance between guides. Divide the number of pixels by the known object size. That is your scaling factor.

Example:

Couch is 84" wide. Place a guide on each side in your image. Let's say its 420 pixels between guides. So scaling factor is 5.

Picture is 36" wide. 36 x 5 = 180. Scale picture to 180 pixels wide to match the couch. There will be some small parallax error (couch appears larger because its closer to the camera than the wall) but you can probably ignore that or scale the picture a bit smaller to compensate.

You don’t have to do much math if you use the command Image > Analysis > Set Measurement Scale > Custom to calibrate the Ruler tool to the known dimensions of that object in your photo like the sofa width. I did this to fit my mockup of specific frame sizes onto a photo of a wall at a site.

You mentioned that you’re using CS6. This feature might be available only in the CS6 Extended edition; because CS6 is now 13 years old I’m not exactly remembering if it’s in the standard edition.

[andy_8039]

Thankyou but im afraid im not skilled enough yet to actually understand what you mean.

[Conrad_C]

When you use the Ruler tool with the Use Measurement Scale option enabled, the readout in the options bar isn’t reporting pixels, it’s reporting the real world measurement in the image, based on how you calibrated it in the Measurement Scale dialog box. So in the demo below, when you see W and L1 reporting 12, that’s 12 feet on the real wall, not 12 pixels in the document.

For all the details, read the Adobe help article about measurement:

I haven't used CS6 in well over 10 years. It's been so long, I don't remember much about it. 

That said, for your purposes, the FRAME tool could be useful. 

Here's a breakdown:

1. The Frame Tool:

• The Frame tool (K) allows you to create rectangular, elliptical, or custom-shaped placeholders. 

• You can then drag & drop images into these frames, and the image will be automatically inserted as a "smart object" that can be resized and positioned within the frame's boundaries. 
• This is useful for creating layouts where images need to fit specific shapes or areas.

Thankyou! However when i rethink what i really need to do is get the photo to size so that the sofa is to scale from my measurement.

[Nancy OShea]

Whichever way you approach this, "smart objects" are your best friend for rescaling elements in Photoshop non-destructively. 

Good luck with your project.

[andy_8039]

Its pretty simple really'

I am trying to create mockups of customers rooms so that i can show them different sizes of frames at scale.

having an image of their room with a sofa against the wall that is to have fames hung, i need to get the image to size so that the sofa matches the width of sofa measurement.

So i know the width of the sofa in cm but how to i get it to that size in the image so that i can add farmes to scale?

I am using an old version of Photoshop.

Thankyou

Going back to Conrad_C's first reply, you enter the physical size in the Logical Length and Logical Units fields. When that's done, the Ruler tool with Use Measurement Scale checked will read out the physical length.

[Conrad_C]

Yes, the answer to your question should be completely answered by the info and the link in my previous replies. This is how it worked for me:

The site sent me photos of the room, and also they told me how tall and wide the wall was. They said the wall was 12 feet wide. This is like how you know how large the sofa is.

I opened Image > Analysis > Set Measurement Scale > Custom, and dragged the Ruler tool to fit the width of the wall, and I entered 12 feet. Now Photoshop knows that 1700 pixels long in the picture is equal to 12 feet in real life. With that done, the options bar shows measurements in feet so that after I add my objects, I can place and size them to scale.

In your case, you want to calibrate the Measurement Scale using the size of the sofa that you were given.

I recorded a more specific demo below, and I realize this is how I should have done the earlier one. So I’ll edit that earlier post with this demo so that it’s clearer for anyone who asks this in the future.

We already covered this in the earlier replies: If you are using Photoshop CS6 Extended, the tool I showed is available to you.

[Nancy OShea]

This shouldn't be hard to do on a flat surface with Free Transform => Scaling. It's a bit trickier with diagonals, but still doable.

Hey Guys

I have realised my last post was a little confusing, my issue is really quite simple.

Which PS version you use?

[andy_8039]

CS6

[c.pfaffenbichler]

Please post sample images. 

Depending on the shape and perspective of the sofa you may need more than the sofa’s width to produce a meaningful scale. 

Do you take the images yourself or are they provided by the customers? 

[andy_8039]

The width is really all i need. I just need the image to be the right size so that if i measure the sofa wisth its correct. Simple.

I have been gradually resizing and measuring untill i get it correct. There must be a smart way.

@andy_8039 I've merged your three threads on this subject. Let's keep it all together or it just gets confusing for those trying to help you.

Have a read of Conrad's post further up this thread. Using the ruler with a custom measurement scale is the way to do this. By co-incidence I've just been doing something similar, matching custom logos to watch dials for mock up where the size needed to reflect exactly as the logo will appear on the dial. I knew both the size of the dial and the size of the logo so was able to set a custom measurement scale for each document, based on the dial diameter, showing how many pixels represented how many mm.  Then by using the measure tool, to drag out the known size of the logo, and then dragging guides to it, enabled me to position the logos exactly at the right size.

Sometime it easier to use Vanishing Point measurament tool. Use Vanishing Point in Photoshop.  May be this can help.
