I no longer try to photograph products from directly above as this always results in annoying shadows. Instead, I now tape the subject onto a white background and in a vertical position. In the image above, I have positioned one white foamcore board horizontally on two chairs and another perpendicular to this.
Using green painter's tape to secure the towel to the board, I photograph the towel as square on as possible and then use the warp feature in Photoshop to straighten up edges. The green tape is erased digitally by using the copy and paste feature; taking a little of the surrounding tea-towel edge.
Here is the finished product image that includes colour correction. Cottage Garden tea-towel can be purchased here in Ferny Green and other print colours.
Hydrangea tea-towel.Lilacs tea-towel. This one was photographed on the wall so you can see that the images taken with the second reflective board look better. I should probably reshoot the Lilacs. All towels are photographed in natural day-light.
