A "slow sync" photograph is one wherein the duration of the shutter velocity is longer than that typically used with a flash (either external or on-camera). This permits more visibility for heritage items or dimmer lights and may have many creative applications. This post will speak via the process in the back of making this shot the use of slow sync:

| Slow Sync Apple Cutting - directly out of the camera (SOOC) |
The shot above turned into created the use of a unmarried publicity and with none virtual manipulation. The crucial factors of creating this shot or a similar one is the use of sluggish sync and 2nd curtain flash.
Second curtain flash way that the flash will hearth on the give up of the publicity, instead of at the beginning. Dig around in the settings on your digicam, and you may locate an option to select second curtain. (On my Canon T1i, it's miles underneath flash manage, built-in flash characteristic placing, and shutter sync.)
In order to set a longer shutter pace and use the flash, you'll need to apply the manual capturing mode on your camera. Keep your ISO low (100 or two hundred) and use a wide aperture to maximize the amount of mild accrued from the heritage in the course of the part of the exposure earlier than the flash. The velocity you pick out for your shutter will depend on the amount of time it takes for whatever actions or effects you want to strive. The final settings for the photograph above have been ISO one hundred, f/five.6, and 20-seconds.

| Wide view of the set up for this shot (before turning the lighting off) |
The setup for the very last shot changed into pretty easy: I wanted an apple, a knife, and a reducing board. My give up table / sewing machine acted as a stand-in for a wooden table, and a sheet strung up between the 2 curtain rods acted as a backdrop. I deliberately positioned the end table a bit distance far from the backdrop so that the backdrop might be outdoor the aircraft of consciousness.
Because I suspected that it would take me several efforts to nail the timing and get the shots of the knife spaced out the way I had predicted them, I knew that I did not need to be seeking to really slicing the apple for the duration of the picture. An greater contact of realism will be introduced through cutting the apple in 1/2 before and finding a manner to keep both halves upright and slightly separated with room for the knife to move through.

| Sample composition set up shot, involved in surrounding lighting fixtures on |
After getting all the components in area, I set my digicam up on the tripod and zoomed in to set up the composition I wanted. I used the apple to set the focus even as all of the lighting fixtures have been still on after which switched the point of interest to manual to maintain it fixed on the apple. The 10-2d countdown timer on my digital camera gave me enough time to start the countdown and get into vicinity before the publicity started out. I additionally turned off all of the lighting across the installation, leaving on simply the lights in the corridor at the back of the digicam.
Moving the knife easily through the complete exposure resulted inside the image above. (The astute among you could word that I also had no longer finished moving the knife when the flash fired and the digital camera stopped taking the photo.) While this smear impact has a number of exciting applications, it changed into not the appearance I desired for this particular photo.
The actual trick at the back of this type of shot is inside the timing. In order to have the knife visible in each of the distinct locations, I figured out that I had to keep it in region for about three seconds in each spot earlier than speedy transferring it down to the next role and conserving. When the knife made it to the bottom, behind the apple, then the publicity might finish and the flash might hearth, illuminating the apple, cutting board, and historical past.
There are masses of innovative applications of sluggish sync photography and 2nd curtain flash. This approach is specifically applicable to growing ghostly images through moving slowly or partially in the course of the final exposure. Give it a attempt, and notice what you could create!
