cactus v4 

Final and Last Update 2

Update 1 since this review

I received my Cactus V4 Remote Flash Triggers yesterday and tried it out on Domo. I ordered a set of Trigger and Receiver and a additional receiver. The Cactus V4 is a update of the original V2 cheap EBay remotes that everyone uses as opposed to Pocket Wizards. Unfortunately, they always have a lot of issues either misfiring or not firing at all unless you modified them. I hated using them because they would always not fire. The Cactus V4 by Gadget Infinity went on sale March 13th and quickly sold out. You cant even see any info about them on their website which is sort of funny. I waited one week for them after ordering and since they ship from Hong Kong, that is not bad. You can get 3-day shipping for like $48 or something like that, but waiting several more days for regular airmail was a way better option.

These are the specs for the set: 

1) New antenna design that increases the reliability and effective distance to 30 meters.
2) New power source for receiver –AAA batteries.
3) 16 selectable channels and advanced anti-interference feature.
4) Compatible with low trigger voltage portable flashes, high trigger voltage portable flashes and studio strobes.
5) Trigger set includes three (3) connection cables while receiver only package includes one (1).

I tested my two receivers out on a Canon 430EX, 580EXII, and a old cheapo Sunpak strobe with a Canon 40D. They fired almost everytime on all 3 flashes. The batteries that came with one of them was low, which scared me at first because I thought it wasnt working but once I changed the batteries, it worked fine. The Cactus V4 was suppose to be able to fire up to 1/500 but it definitely was not able to do it. I was able to shoot at 1/100 to 1/250 and it worked fine. I didnt do much testing on the range but I dont usually need a big range since I am usually not too far from the subject and the flashes.

Overall, I am pretty happy and impressed with them so far but I have not tested them out that much yet. I hope to try it out on a model shoot soon.

Drobo Review

 drobo thumb Drobo Review

I have always heard good things about the Drobo by Data Robotics, Inc. and I finally decided to purchase it to use as my main storage backup device. I previously had a Yellow Machine 1TB Nas Server with four hard drives and a RAID5 setting. One of the hard drives failed however, and the network was not 100% reliable so I decided to abandon it and try the Drobo. I went with the Drobo 2nd gen because I am not a fan of 1st gen products so I spent $150 more. The features of the Drobo include:

New Features:

  • FireWire 800
  • Enhanced USB 2.0 performance
  • Quieter, cooler operation

Key Features:

  • Redundant data protection
  • Hot expandable up to 16TB
  • Mix and match drive capacities

The best thing about the Drobo to me is the fact that you can mix and match hard drives. It takes SATA hard drives and instead of the standard RAID, it uses a propriety software to automatically store your data among the drives that you have installed. If one drive fails, you simply remove the drive and replace it with a new hard drive of any size. I have used my Drobo for about a month now and I am pretty satisfied with it. I have 2 x 1 TB Western Digital Green Power Drives and 1 x 80 GB hard drive.

Unfortunately, the Drobo uses quite some space for overhead and protection. Out of the 2.08 TB of available hard drive space, I get about 1TB worth of space. Having less than half of the space available versus actual hard drive space is a pretty big sacrifice and is basically along the lines of RAID1. Obviously a RAID5 or 10 would be a lot better. Using a 1TB RAID5 with four hard drives gave me about 750GB of hard drive and is great to only have to give up 1/4 of the available space. The good thing about this versus a RAID1 is that with a RAID1 (mirror) which usually consists of 2 hard drives of the same size, if one drive fails, you have to replace it with the same exact hard drive. You also cannot add more space to the RAID1 configuration. With the Drobo, you can continue to add more space or replace any one of the hard drives at any time if you need more space.

The Drobo Dashboard is pretty easy to use and to configure. Mounting the drive is pretty simple. I did not want to spend the extra $200 for the Drobo Share network attachment. It sort of sucks that they did not build in a network connection which obviously gave them a great reason to sell an addon to make more money. Only being able to connect using FireWire or USB is a little ridiculous and hopefully they will build it into the next version. So in order to share my Drobo among multiple computers, I have to share the mounted drive and it only works if my computer is on. Connecting the Drobo to my Windows computer using USB is fairly reliable but I have noticed a couple things that bug me about it so here are some of the issues that I have with the Drobo.

When the Drobo is connected to the computer, it takes a very long time to boot up the computer. I am running Windows XP on a 2×2.4GHz AMD 4600+ Processor with 4GB of RAM. It is not exactly a slow machine. The way it works is that for every 1TB volume size, it is suppose to take 1 extra minute to boot up. So technically it is only suppose to take 1 extra minute to boot up, but it definitely took longer. It slows down the actual computer BIOS boot up screen and it also slows down the Window startup as well so it affects both the computer BIOS bootup as well as the OS. I also resolved any Legacy USB issues that they suggested, did a XP BIOS update, and the Drobo firmware update. The easy solution to this is to just unplug the USB cable from the computer before you boot up, and it boots up just fine. Once it is fully booted, I plug the USB cable back in, and the computer detects the Drobo and mounts the drive just fine. it does however do an Autoplay almost everytime which gets annoying even after I tried disabling AutoPlay on the mounted drive. The best alternative to this problem would be to get the DroboShare, but spending an extra $200 just for network capability is not worth it to me.

Other issues I have had are that sometimes if I leave my computer on idle or sleep mode and return, the mounted drive gets unmounted and I can’t seem to remount it except to unplug the USB and plug it back in again. Copying and transferring files is pretty good but I do notice that it is slightly slower as opposed to copying between internal hard drives since SATA II is suppose to transfer at 3GB/s and USB 2.0 transfers at 480Mbps.

When the computer is on, the Drobo is on and when the computer is off, the Drobo turns off. I am not sure if this is a good thing or not since normal NAS or storage servers stay on 24/7. Turning the Drobo on and off may make the hard drives more prone to failure but I dont think it makes a significant difference. Overall, I think the Drobo can be a good solution if you need a basic storage device. Depending on your needs, you may be better off with a Storage Server or Media Server if you want something that has more functionality. It is also compatible with different OSes. I am obviously a technical person so it may be a good solution for non technical people or if you just want a basic reliable storage device. I would recommend the Drobo Share to ease some of the issues that i have.

Don Giannatti Lighting Essentials Workshop Review

 Lighting Essentials Workshop Review 

I attended Don Giannatti’s Lighting Essentials San Francisco Workshop on August 23 & 24th, 2008 and I thought it was pretty good. For $299, we got a two day workshop that included a brief overview of studio lighting, extensive strobe lighting overviews, and a chance to shoot with a good amount of different models at different locations. This was not my first workshop nor do I consider myself a beginner photographer. I would say I am a intermediate photographer since I can comprehend most of the photography concepts. I have gone to several model mixers, and had several of my own model shoots where I do my own lighting so it was not my first time working with models. There was also a makeup artist for the first day which can always help make the models look even better.

I enjoyed the workshop and it was good for all levels from beginner to intermediate photographers because there is always something new to learn in photography. The workshop was intended to be strictly a lighting workshop that focused on lighting and that was exactly the reason why I took the class. Don Giannatti is a professional photographer who has over 40 years of experience and has some good expertise on shooting specifically with strobes. Using strobes or external flashes along with reflectors can be great because it does not require you to bring around big studio lights and battery packs.

 Lighting Essentials Workshop Review

Day one of the workshop started at the Holiday Inn in South San Francisco as Don went over a little bit about lighting and his background. The class had about 20 students,  which was 5 over his normal workshops but due to a computer issue, he was not able to close the attendance signup. This wasn’t a huge issue except for the one or two photographer who always goes off with a model and shoots instead of listening and letting the teacher drive the class which was quite annoying. Photographers were asked to bring their own studio lights for the first day and we had some pretty good lighting setups. We spent some time doing some studio light testing at 4-5 different stations using softboxes, umbrellas, and reflectors. This helped us see the differences between the types of lighting as well as the placement of the lighting and reflectors. The studio lighting was all setup with Pocket Wizards and half the photographers had their own while the other half had to ask people who were willing to let others borrow them without hesitation.

After lunch, we went outside the hotel for some outdoor shooting in the hotel parking lot area using strobes and wireless triggers. For the studio setups, we had used mainly Pocket Wizards, but outside, the other half of the class used Cactus V2 triggers. This was not a huge problem but did cause some minor confusion as you had to basically be in your group using one or the other or wait and ask someone to borrow their triggers. Strobes were not an issue as everyone had at least one strobe whether it be a Nikon, Canon, or SunPak external flash. The great thing about using strobes, is that by attaching a Pocket Wizard, Cactus V2, or any other wireless system, you can basically use the flashes all together and not have any issues. At 5pm the class was suppose to end but one model stayed around and we did some more shooting in the hotel lobby area and outside as well. We took advantage of the natural lighting and Don showed us how we can use reflectors with natural lighting to light the model.

The next day we met at Union Square in downtown San Francisco. The location is great for shooting, but not exactly the best spot for a workshop on a nice sunny Sunday. We had a lack of models on a Sunday morning not surprisingly but did manage to find some tourists to model for us. We even managed to find a girl who just arrived in the United States from Europe for school and ended up modeling for us the whole day. We used strobes and reflectors at different spots to try out the different methods of lighting the model. We then moved to a alleyway and the organization of the workshop began to fall apart. More models finally showed up and photographers started shooting with them on the side and started wandering off and shooting like crazy like they were practicing to be Paparazzi. The goal of a workshop is to let the teacher drive the class and teach the students. The models were mainly used as the tool and subject but some photographers acted like they have never seen a hot young chick so they go shooting like crazy and forget that this is a workshop. After lunch, we walked over to the Yerba Buena Gardens and broke off into groups to do some lighting exercises. That did not turn out so good because photographers basically started doing their own thing and took models with them as well to do their own thing. People started wandering all over the place and basically it was just like the survival of the fittest in trying to learn as much as you can in finding out where Don was and seeing what he was showing and teaching. My group ended up not knowing where everyone was and I ended up wandering around with two of the models trying to find the rest of the group.

 Lighting Essentials Workshop Review

Overall, I think the workshop was worthwhile. The first day was great and the second day was a little disorganized. I knew some of the lighting ideas taught in the class but Don emphasized the idea of knowing how to find out the proper exposure of the subject and how to set your strobes accordingly. I actually never used that way of lighting my models and basically just used the basic shoot and adjust method as opposed to using a light meter. It definitely can be useful to find the right exposure using a light meter and then adjusting your strobe to that exposure and firing it at the right distance. All my shots that you see here have some post processing applied to them. That was not a focus of this workshop so all of my post processing work here is from my own skills.
