Photography is all about creating images.


Whether you choose to take conventional landscapes, macro images, portraits or even create images using torch light there is certainly some element of image making which will appeal to everyone.

You don't need the most expensive camera equipment to enjoy this fascinating hobby and in many ways the simpler cameras allow you to concentrate entirely on the image creation rather than spending a considerable amount of time reckoning with the camera controls and menus of more complicated cameras. 


Through this blog, and my youtube channel (


I would like to share my passion for image making and try to pass on any hints, tips and knowledge to anyone who cares to stop by and read or watch.


If I mention a particular make or model it doesn't mean I have been sponsored by the manufacturer to say so, it's because I felt is worthwhile because of some feature that may be of interest to other users.


The process of creating a beautiful image is both an art and a science. Art because we need to comprehend a basic set of rules which will make our images stand out and offer more viewing pleasure and Science because we need to understand some principal factors which influence the exposures captured by the camera.

Having spent many years working in the imaging technology industry and taking pictures, trying to improve my skills and knowledge, I thought it would be enjoyable to exchange opinions and experiences with other photography enthusiasts.


In this blog my aim is to talk about digital cameras their technology and quality objectives an also software for digital processing.


I'm not affiliated with any company or manufacturer so all the reviews are totally unbiased. I've made some bad purchasing decisions along the way and hopefully I can help you avoid the same mistakes.


I'm not a professional photographer, I don't earn my living though photography but I do love being out and about learning by doing and then passing on those experiences to anyone who will listen.


I would also like to showcase some of mine and your images, offer some shooting techniques and everything that may be of interest to a passionate photographer.

Again I am disappointed to see the production costs for the colour version. From the basic print price and then adding on the Amazon mark up puts the cost of the book into a price point where I cannot justify adding my own earning from the book.

 Having just received the final proof edition of the book I cannot really justify recommending the colour version over the black and white as the paper used does not render the colour images with the subtle tones which are needed in some photo illustrations. For graphics this would be fine but really it needs semi-gloss paper for the detailed images. The B&W version is good enough for the detail and then if you need clarification the PDF version would allow you to view the topic. The PDF also has the extensive search facility where the hard copy does not have an index.


With each purchase you will get the full colour PDF of the book and this does give the required quality for screen reading on a variety of devices from tablet to PC screen.


Alternatively I have released the full colour PDF file ahead of the Amazon hard copy release and unless you specifically want hard copy then this is my recommendation for this guidebook.

Schematic for the working version of the FZ200 AGC Defeat Unit


The final circuit turned out to be more simplistic than I had originally thought.

I assumed that the input would need to be a sine wave to prevent harmonic distortion if a square or triangular wave was used for the input to the camera. In testing I found that the camera would still perform well with a square wave input so I decide to try both an astable multi-vibrator pair of transistors running at 20 KHz and a NE555 timer IC.

In the end I decide to use the more stable 555 IC as the frequency remained solid even during the battery run down.

Here is the schematic for the project.

The timing is done by R2-C2 giving 20KHz. The output from pin 3 is attenuated by R1-R3  to 7-8millivolts at the camera input after being coupled with the mic input and allowing for its impedance.

the right hand mic input goes straight to the camera input whilst the left hand input has the 20KHz signal injected into it.

If you wanted to get finer control of the AGC defeat voltage  input R3 could be substituted with a 27K resistor and a 100K potentiometer in parallel with it. The output would be taken to C3 form the wiper of the pot. This would allow the output to be set for 0V to about 10millivolts.

The unit is powered by a PP3 9v battery.

Here is the built unit. I used a stereo splitter cable from £/$ store to get the wired 3.5mm inline socket. The 2.5mm plug I wired but again it could be obtained from a 2.5mm to 3.5mm audio cable if you didn't want to have to solder one up.

The version 2 of this unit now features a trim pot (22K) in place of R3 ( the wiper connects to C3) so that you can adjust the level of the bias signal sent to the FZ200. Adjust to about 1/3 or the rotation as a starting point. Do a test recording with the unit on and adjust the trim pot until the background noise doesn't increase when you stop talking.

Modifying the Qutaway 5v to 9v Conversion cable for 8.4 Volts


This is the pcb from the Qutaway product. The case is easily removed by inserting a sharp blade at each corner and prising the two halve apart.


on the left is the input from the USB plug and on the right the output cable.


We are going to add a series diode in the red output lead to drop the 9v to 8.4v as shown below.


Note that the adaptor featured here will support video recording or burst mode with electronic shutter and single mode shooting with the mechanical shutter operative otherwise the camera demands too much current and resets when used with the FZ2000/2500, on the FZ1000 it is OK.

Here you can see the addition of the GP150 silicon diode (or a 1n54 series diode) connected in series with the red lead.


De-solder the red lead from the pcb, insert the diode with the anode (plain end marking) to the pcb and then connect the red cable to the cathode (ringed end) of the diode.

Ensure the diode is clear of the pcb when installed.

Re-fix the covers and add suitable marking to the unit to designate it now to be 8.4 volt output.


The completed unit.
