Taking good clear pictures with a decent amount of lighting will generate more swap interest which equals more swap offers (this is what you want; you want to get rid of your old stuff that you don’t use for stuff that you really want or could use). I am going to list some simple ideas for you.
(1) Use adequate lighting (turn on all the lights, if at all possible or try snapping the pics when it’s light out). Some people take pictures outside to get the maximum effect.
(2) Try to take clear pictures. If there is a shadow or a small amount of blurriness, someone might request additional pictures, in order to see the item better. This will take more time and work on your part. If you are busy like me, might as well, get it right the first time to avoid all this additional time and effort. If you have several pictures to post, you might want to post the best picture first, something you think might grab someone’s attention first.
(3) If taking close-up shots of an item to show detail of some sort (logo, brand name, pattern, material, color, etc.), use the macro setting on your camera. You might have to play around (take several test shots) with each setting (indoors, flash-on, flash-off, etc.) to determine which setting gets the best results. If there is any damage or flaws (stains/holes/rips/worn areas/broken zipper), it’s a good idea to take pictures of this, so as not to misrepresent the item’s condition (full disclosure).
(4) Use tools for size scale comparison (to include in the picture alongside the item/s)- for jewelry, use a dime or a pencil/pen, for handbags, use a doorknob, a hook, a hanger, or a measuring tape. Some people use a can of soda to illustrate. Some people have mannequin forms. Some people use a model to display the handbag on her arm (a closeup of the arm and upper torso, minus her head). Some people use themselves wearing the item, but then black out the face, so as to have privacy.
(5) Avoid lots of distracting objects or busy prints in the background. Some people use colored sheets in a solid color (black velvet, red felt) or a simple fabric to highlight the item. Some people provide their user names on slips of paper beside the item/s, to authenticate that the item is in his/her possession; that the photos are not taken off the internet, or stock photos (these pics usually feature an all-white background).
(6) Avoid putting the item on the floor, as this is a turnoff for some people, like me (one of my pet peeves). This may indicate that the item is dirty as the floor, whether it be carpet, tile, whatever, is a high-traffic area filled with germs and footprints. I usually use: the sofa, the bed, a chair, the ottoman, a hanger, a doorknob, or a hook.
It’s amazing how many people do not post pictures of their items on these websites. These people will not get as much swap interest, thus less offers. I rarely swap for items that are not pictured (some book sites do not require pictures, as the pictures auto-populate when listing books with the ISBN number). It’s also amazing that some people do not put much thought into their pictures, as well. It’s easy to grab a swapper’s attention by using pictures to illustrate your items in the best possible manner. I hope that you found my tips useful.
