Today’s Question: I watched one of your lessons that covered the Oil Paint filter in Photoshop, and the effect looked nice. But when I apply the filter to my own images the effect is so small it looks like a basic canvas texture rather than an oil painting. Is there something I’m missing?
Tim’s Quick Answer: In my experience you get the best results with the Oil Paint filter in Photoshop by first resizing the image to around 2,000 pixels or so on the long edge.
More Detail: The Oil Paint filter in Photoshop stands out to me as one of the most impressive creative filters, in large part because many of the other creative filters are very simplistic and outdated. The key to getting the best results with the Oil Paint filter is to apply the effect to an image that has been resized to around 2,000 pixels on the long side.
Reducing the pixel dimensions is obviously reducing the total amount of information in the image, and so it is important to create a copy of the original image for this purpose. For example, after opening the image you want to apply the effect to you can choose Image > Duplicate from the menu. In the Duplicate Image checkbox I recommend turning on the “Duplicate Merged Layers Only” checkbox so the duplicate image will be flattened, while preserving any layers in the original file.
Next, choose Image > Image Size from the menu, make sure the Resample checkbox is turned on, and with the popups for Width and Height set to Pixels enter the desired value for the larger dimension. Be sure to keep the lock feature enabled using the button with the chain link icon to the left of the Width and Height fields so the aspect ratio won’t be altered. Click OK to resize the image.
You can then apply the Oil Paint filter. If you want to have greater flexibility you can apply the filter as a Smart Filter, which means choosing Filter > Convert for Smart Filters from the menu to convert the Background image layer to a Smart Object first. Then choose Filter > Stylize > Oil Paint from the menu, and adjust the settings for the filter to create an oil paint effect with your preferred look.
