Creating a montage from 32 separate, different photos

[AllotmentBeans]

Our road community wants to create a special reminder of the fantastic work our UK NHS key-workers are doing in these difficult covid-19 times. We have distributed 32 A1 sheets of paper to 32 different people. Each person will produce a unique painting/textual work of art based around an overall design broadly with a rainbow symbol. There will be NO overlap so I can't use Lightroom Photo Merge.

We want to photograph each of the 32 sheets and then combine the 32 photographs in an 8 x 4 matrix  and merge/create 1 big photograph which we intend then reduce in size and get printed on metal and placed at each end of the road.

Please can anyone advise how to do it?

Many thanks

Dave

A montage normally blend and mask images into some kind of artistic composite.  It Sound like you just want to lay out your image image into a matrix if images with no overlap 8 columns 4 row.  That should be quite easy to do in Photoshop.  Load  your 32 A1 size images into a stack.  Menu File>Scripts>Load Files Into a Stack....   All Image should be the same A1 Size 594mm wide by 841mm high at the same print resolution so all images will have the same size canvas.  

They use menu Image>Canvas Size... a set the canvas size to 4,5752mm wide by 3,364mm high  8wide 4 high.

The use menu View>New Guide layout.... and set 8 columns 4 rows.

Then use the move tool to move the image layers into to the guide layout they should snap into place.

Thanks Stephen. A friend has also shown me how to do it using Print to file in Lightroom by creating a template
