Filling in the Image Logbook

The next stage is to fill-in the image logbook: click here to dowload the logbook then print it out. The image logbook can be a bit confusing at first. But it is important to get this bit right, because later on you'll be entering this data into the Walkabout Generator. This section of the tutorial takes you though the stages involved.

In the example below a few lines of an image logbook have been filled in to show you what it should look like. The example table has been made up from the information given in Figure 2. If you study this figure carefully, you'll see that while standing at station A, three photographs were taken: one looking straight ahead (A1); one turning slightly to the right (A2); and one taking a sideways step to the right (A3).

Now, imagine you are standing at Station A holding a stack of all the photographs you have taken of the monument, with photo A1 - the first one you took - on top. If you were to look up, you should see roughly the same view in front of you, because photo A1 was taken looking straight forward from Station A (as in Figure 2). Now imagine turning left. It's a nice view, but as you go through your stack of photos you find that none of them matches it. That's because no photographs were taken by turning left at this station (as Figure 2 shows). The same goes for the movement 'step left'. No photographs were taken in that direction either.

If you now look at the example image logbook below you'll see that in the first line - the row for photo A1 - we've entered dashes in the boxes for both of these movements. This is to indicate that no photographs were taken stepping or turning left from Station A.

Image id. Step Left Turn Left Forward Turn Right Step Right Caption
A1 - - B1 A2 A3 View looking due E.
A2 - A1 B2 - A3 N-W corner of Object 1
A3 A1 A2 - E3 E2 W. face of Object 1
B1            

Lets make another movement. If you were to 'move forward' from Station A, in a straight line, what would you see then? Not photo A1, because you'd be standing in it. Shuffling though your stack of photographs you'd soon discover that the image that most closely resembles the view you now have is photo B1, because it was also taken looking straight forwards, this time from Station B. So, returning to the Image logbook, in the 'Forward' column for photo A1 we have entered 'B1'. This is the image that relates to A1 as a result of this movement.

It gets more interesting on the right-hand side of Station A. Imagine again that photo A1 is on top of your stack of photos. This time you turn to the right and now you can see the corner of Monument 1 (see Figure 2). Flicking through your photos you find that one of them resembles this view very closely; it is photo A2, which was taken by turning right from Station A. To enter this relationship in the image logbook we have entered 'A2' under the 'Turn Right' heading for photo A1.

There is one other movement we can perform from Station A: a step to the right. Using the same logic, and making use of the plan in Figure 2, what should be entered in the 'Step Right' box for photo A1?

Finally, note that we have added some comments about each photo in the caption column that provides addition information about each image. It is important to fill out this column since you will be required to enter this data into the Walkabout Generator later on.

Hints and Tips

A useful tip when completing the image logbook is to ask yourself this question for each of the photographs you take: what would be the next photograph I would see if I made each of the movements listed along the top of the logbook, i.e. turn left, step right etc?

IMPORTANT: Some cells in the image logbook will remain empty, i.e. there will be photographs that do not relate to one another. This is quite normal. However, you should mark all empty cells with a dash ( - ) to make this clear.

For the more adventurous, note that by moving forward and turning right both at the same time you effectively describe a rightward curve.
