Adobe Photoshop is a perfect program for creating realistic interiors for Interior Design mock ups. To create a room like the one illustrated here, first open Adobe Photoshop and create a new document with the dimensions of 1280 by 720 pixels, or A4, etc, depending on the purpose of the image. For web work make the resolution 72 pixels per inch, and for print work make the resolution 150 ppi for in-house printing and 300 ppi for commercial printing.
Next open an image of wood grain - this can be downloaded from the internet, but if you do so make sure that the size is large. This will ensure that the image is manageable and does not appear pixilated. We wish to view the images side by side, therefore go to the Window drop-down menu and choose Arrange and one of the Tile options. This lets us view the two images side by side. Next select the Move tool (V), click on the wood grain to select it, then click and drag it across into the blank canvas.
Now right-click on the new layer to Convert to Smart Object. The layer will never be quite the right size, therefore go to Edit, Free Transform (or Control+T). Pressing down on the Shift key as you click and drag on one of the corner anchor points will scale the layer proportionately. Alternatively you may choose Edit, Transform, Perspective or Warp. Or press down on Control to move each anchor point separately.
This comprises one wall of the room. Next we need to copy the wall - we do so by pressing Alt (Mac: Option) and moving with the Move tool. Copy four times to give us the two side walls, floor and ceiling. Adjust the roof layer by going to Object, Arrange, and Flip Vertical. Rename each layer for ease of use later on.
Source a carpet image and copy it to the clipboard. Then double-click on the floor layer to edit the Smart Object, and paste in the carpet image. Press Close to exit, thus updating within the room file.
To add shadows create a new layer and right-click on it to Make Clipping Mask. Then use a large black soft-edged brush to create shadows in each corner of the room. If the shadows look too dark adjust the layer opacity to 50%. Repeat this process for the other walls.
To cut out the window in the back wall select the Rectangular Marquee tool with a Feather value of 2px. Then go to the Select menu and choose Inverse. Lastly click on the Layer Mask button at the bottom of the layers panel, thus revealing the white background layer.
Next open a beach image and copy it into the room file, dragging it to the bottom of the existing layers. Scale down to fit the window space making sure to match the horizon with the converging parallels of the walls.
This completes the room itself. We would now open images of humans and furniture and light fittings. Copy them into the scene and select the objects before masking off the background of each layer. We could also create fake shadows on a new layer with the Lasso tool and a Feather value of 10px, also reducing the layer opacity for a more subtle effect. It's also a good idea to experiment with the Lighting Effects Filter.
As we can see Adobe Photoshop is an ideal program for creating mood boards for interior design before creating the model in a 3D program.
