Ready to experiment photographically with far-out color and an alternative medium like cotton? Blue Sunprints provides exactly what you need to make awesome orange prints in the sun with their Cyanotype Cotton Squares - 6 x 6" (50 Pack, Orange). The resulting print will be the original orange color wherever you placed your design and the negative space will be a deep, dark hue that pushes all that brilliant orange to the forefront. Your images will pop! Whether you're creating standalone works, or you're incorporating them into clothing or other fabric, your images are sure to get noticed.

Each cotton square is pre-washed and pre-treated, and all 50 pieces come sealed in a black light-safe bag. Take them out right before you're ready to expose for the freshest, brightest image possible. Once one side is done, the cotton square can be turned over to expose a totally different design on the other side. When finished exposing, rinse the sheet clean. Due to its archival nature, you'll be able to wash and rewash the cotton without losing contrast or color.

1. Choose your design
Your design choices are nearly endless. Here are some ideas: Drawings or photographs that have been printed on transparencies or acetate. Actual objects such as leaves, flowers, string, toys, letters, hands, jewelry. Experiment with photographic negatives, x-rays, cut-outs or clip art, lace, and sheer fabrics. Use your imagination - try anything! Once you have chosen your design, lay it on the cyanotype material. To hold your design in place during your sun exposure, use a piece of clear glass or Plexiglas for a tight contact or lay your design loosely if there is no wind. You can also choose to pin your design down into a piece of cardboard or foam core

2. Expose your sun print
First make a test print by exposing your design in the sun for different lengths of time on a small section of cyanotype material (use the test print chart included in the instructions as a guide). Then choose the best exposure time to get the tone you want. To print on both sides of the cyanotype material, first expose one side to the sun using your desired exposure time, then turn the material over, lay the same or different design on the second side and expose it for any time you choose. Once you have exposed your sun print, remove your design

3. Rinse your sun print
When you rinse your print in water for a few minutes (until the water runs clear) your cyanotype print will begin to appear immediately. The print will be a dark hue and your design will be the original orange color of the paper. If you want a darker effect, spray hydrogen peroxide on your rinsed print. The darker color will appear instantly

Related Questions and Answers

Q: 1. Will this lens work on the Canon EOS R? Thanks

A: You can use it on the EOS R with the EF-RF adapter but this lens is for crop apsc sensor and the EOS R has a full frame sensor, so you won't be using the full sensor of the R, less than half of the available megapixels will be used and the corners of the image will be black like looking through a key hole, so I do not recommend it for that camera.

Q: 2. Does this lens extend in physical length throughout the zoom process or does the lens remain the same physical length throughout the zoom process?

A: It maintains the same external length throughout the zoom range.

Q: 3. Will this work with d850??

A: No, there are no adaptors to convert Nikon mirrorless lenses on the Z-mount series to Nikon DSLR cameras. ALso this lens is a NIkon DX version which is not recomendad on full frame camera bodies. The most similar option compatible with Nikon D850 Nikon AF-P NIKKOR 70-300mm f/4.5-5.6E ED VR Lens BH #NI7030045AFP.

Q: 4. Sigma 18-35

A: This is the 50-100. Its very sharp and matches the 18-35. I own both and love them both. Great glass.

Q: 5. Is the tripod collar removable?

A: Thank you for your interest in Sigma products. The tripod collar for the 50-100mm f/1.8 DC HSM Art Lens for Nikon F is not removable.

Q: 6. I just got this lens and I'm noticing it losing focus when zooming, is this a setting I need to change in camera or is it the nature of the lens?

A: This is normal for a still photography lens. Only very high end cinema lenses are truly parfocal (retain focus across zoom range).

Q: 7. I'm wandering if this lens is too heavy for my Fuji lens mount. Should I use lens collar or is the weight of the lens fine for the body?

A: This lens is amazing. I use it 60% of the time,(10-24 the rest). My grandkids where just here in Florida for a week. The lens, handheld, was perfect to capture the kids swimming in the pool, in the ocean, or just out and about. Its my favorite lens and I've yet to use it with my tripod. Super sharp and no problems with the mount. Keep in mind most of the time you are grasping the lens rather than the camera. It's almost as if the camera is mounted to the lens rather than the lens being mounted to the camera.

Q: 8. what is the 35mm equivalent of lens with 1.4 teleconverter?

A: The FUJIFILM XF 50-140mm f/2.8 R LM OIS WR Lens with the 1.4x teleconverter is, 107mm - 319mm (35mm equivalent)

Q: 9. This lens is the ideal focal length for me to shoot high school basketball games. It also matches nicely with my 18-50 Sigma, but no image stabilization and one reviewer panned the auto focus speed. I'd be shooting at a high shutter speed anyway to capture the action. Can't make up my mind. Help?

A: Depends on where you are standing or sitting.On the court floor, where I shoot from, a 35mm lens on a DX body can sometimes be too long. So a 50-100 would be way too long.From the bleachers, probably fine.BTW, I shoot with a 35mm f/1.8 lens, 1/1000 sec, f/2, ISO=3200.I suggest renting the lens, and testing the AF speed for yourself.

Q: 10. Is this lens compatible with the Canon DPAF for video?

A: The DPAF (Duel Pixel AF) is camera based and this lens is compatible.
