After
reading a number of articles on photographic holograms, I was intrigued by the
possibilities. The holographic effect is achieved by using two identical
photos, one of them on a transparent fabric, separated by a spacer. The
articles I read nominated stretcher bars to provide the spacer, but I decided
to use an inexpensive paint canvas to provide a frame and to create the space
needed to produce the effect.
Preparing the frame:
I chose an
8”x10” canvas. By turning it over and using the back of it, I had a ‘box’ with
wooden sides and a canvas base, with a 5”x7”opening - perfect for a photo. I
left the canvas attached to the frame, and discarded the wedges that came with
it. I wasn’t sure how much of the inside of the box would be seen once it was
all assembled, so I painted the inner sides with black acrylic paint, making
sure that there was paint inside the grooves provided for the wedges.
Preparing the photos:
I chose a
photo of the beach at the northern tip of Denmark taken on a visit this year. I
made some adjustments in Photoshop to brighten and sharpen the photo; then
printed it once on cotton for the base, and once on semi-transparent silk
organza for the overlay. It is important that the photo on the organza is in
the centre of the sheet, but you can be more conservative with the cotton. I
used a Jacquard Cotton Sheet bought from
www.ozquilts.com.au
($22.95 for a pack of 10), and ExtravOrganza also from ozquilts ($17.95 for a
pack of 5). After printing, I cut the cotton sheet to the size of the photo but
left the organza sheet whole.
Attaching the first photo to the canvas:
I was not
sure how the photo printed on cotton would react if I used a wet glue to attach
it to the canvas base, and I knew it would be awkward to get an iron into the
box to attach it with vliesofix, so I decided on a two-stage process.
I first
attached the photo to a piece of adhesive backed felt with vliesofix, then
peeled the backing off and pressed it onto the canvas base of the box with hand
pressure. This seems to have been successful.
Attaching the overlay:
I lay the
silk organza sheet over the top of the box and carefully and evenly stapled it
all around the top. The trick here is to make sure that the image on the
overlay is exactly over the base image. Once it was securely fastened I trimmed
off any organza overhanging the outer edge of the box and made sure that all the
staples were well embedded in the timber around the top of the box.
Finishing:
To complete
the picture, I added a frame of stiffened felt (available from Spotlight in a
variety of colours) to cover the top edge of the box. I cut it 8”x10” with a 5”x7”
cutout in the centre and attached it to the top of the box with gel medium. As
a final touch I also used gel medium to attach some small stones I had picked
up on the beach. It has held them well.
Notes:
I am not
sure that this is the best sort of photo for this technique – perhaps something
with more action or colours or contrasts etc might be better. I also now wonder
about the necessity of the base photo being printed on fabric. Printing it on
photographic paper would make it sharper and clearer which might improve the
final effect. Each of these ideas will be tested in my next project!
