No – take them all on your camera’s best setting (I use high quality jpeg), then resize them all in Photoshop afterwards. I use a standard size for my pics (700×450 pixels) and once the pics has been sharpened and resized I paste it into a new window which is the required size and use the move tool until I’m happy it’s about in the middle of the frame. I then add my copyright, save as a Jpeg using an image compression of 9 on the scale.
