Think about the task. You need to take a picture every time a pulse appears. This suggests a single loop with a "Timer" and a "Camera". The Timer could also have a signal that says "All Done", and lets the loop exit.
OK, so what does the Timer look like? You need 60 pulses at 1/second, followed by 30 pulses at 1/sec. One thing you could do is to realize that this is equivalent to 90 pulses at 1/sec, but we'll stick with two sub-timers. So how do you create something that happens once per second for 60 seconds? How about a For loop, count of 60, inside of which is a Wait for Next Multiple, wired with 1000 (1000 msec = 1 sec)? But you need two loops -- one way to do this is to wrap the Timer loop(s) inside another For loop, this one set to 2, one for each timer. Put a Case statement inside, wired to the Loop Index (i). Inside the i=0 case, put the 60-second timer. Inside the i=1 case, put the 30 second loop, Inside the Default case (all others), put the logic that says "We're done". Note that the "two-timer" For loop, inside of which are your two timers, output a single "Take a Pix Now" signal.
Try coding some of this up. Simple For loops, simple Wait until Next Multiple, possibly using a For loop with a Case inside it to count down through numbered states ...
This might not be the Most Elegant way to solve your problem, but it is straight-forward, respects the Problem Requirements, and, if you look at the form, it is easy to see that it fulfills the "do this at 1/sec for 60 seconds" requirement.
