How can we provide a dynamic range in

Twitter Facebook Pinterest Share You’ve probably heard the term Dynamic Range (DR) used a lot in photography articles and camera reviews, but what exactly is it, and how does it relate to your photography and camera skills? When I first That’s why we created this beginner-friendly guide – soon you’ll understand the key points about dynamic range and have the confidence to use it to your advantage in creating awesome images in 2023. We’ve also included 6 helpful tips to help you maximise the dynamic range of your current camera. Let’s dive right in! In a nutshell, dynamic range is the difference between the lightest and darkest tones in a photograph – from pure white to pure black. DR is essential as every camera has a sensor that records image information in tones or grey shades. Some sensors can only see the detail from dark grey tones to light grey tones – but not quite pure white and black. More importantly, a camera’s dynamic range refers to how many increments the image sensor can detect between pure black and white – plus the tones in between. Those increments are known as stops, stops from here on to keep it simple. Stops are the unit of measurement used in photography for reading and controlling how much light a camera can see. If each increment in the dynamic range is a single stop, then how many increments a camera can read determines how many stops of dynamic range it can capture. Keep in mind that a camera sensor’s ability to detect a greater dynamic range depe...

In this Article • • • • • • • • • • • This article will demonstrate how to create a Dynamic Range in Excel VBA. Declaring a Referencing Ranges and Cells When we reference the Range or Cell object in Excel, we normally refer to them by hardcoding in the Range Property Using the Range Property, in the example lines of code below, we can perform actions on this range such as Range("A1:A5").Font.Color = vbRed Range("A1:A5").Font.Bold = True Cells Property Similarly, we can use the For example, the cell address A1 can be referenced as: Cells(1,1) Or Cells(1, "A") To use the Cells Property to reference a range of cells, we need to indicate the start of the range and the end of the range. For example to reference range A1: A6 we could use this syntax below: Range(Cells(1,1), Cells(1,6) We can then use the Cells property to perform actions on the range as per the example lines of code below: Range(Cells(2, 2), Cells(6, 2)).Font.Color = vbRed Range(Cells(2, 2), Cells(6, 2)).Font.Bold = True Dynamic Ranges with Variables As the size of our data changes in Excel (i.e. we use more rows and columns that the ranges that we have coded), it would be useful if the ranges that we refer to in our code were also to change. Using the For example Dim lRow as integer Dim lCol as integer lRow = Range("A1048576").End(xlUp).Row lCol = Range("XFD1").End(xlToLeft).Column Last Row in Column As there are 1048576 rows in a worksheet, the Last Column in Row Similarly, the lCol will move to Column XFD whi...

I’d always believed that Named Ranges in Google Sheets would only accept static ranges and not formulas like Excel, which makes them less powerful of course. (Check out the Named ranges sidebar and you’ll see what I mean. No place to add formula-based dynamic ranges in there.) However, there is a clever trick using the Drumroll please… Using formulas in named ranges to make them dynamic Step 1: Create a formula whose output is a range reference in string format, for example: =SPARKLINE(INDIRECT( dynamicRange)) Once these are setup, if you go back and change the value in cell B1, the range will update and the formulas in Step 3 will also update. Can I see an example worksheet? How does the formula for dynamic named ranges work? • Formula to count last row • Formula to create a string range reference • This cell is a named range: dynamicRange • SUM formula using INDIRECT and the named range • SPARKLINE formula using INDIRECT and the named range Dynamic named ranges! Woohoo! This is one of my all time favorite Google Sheet tricks. Hi Rachit, I tried this with a sheet labelled ‘1’ and my vlookup formula looked like this: =vlookup(A1,'1'!A:R,2,false) It worked fine when I tried, so not sure what’s going wrong with your formula. Have you tried to return a column outside of the range A:R, by using an integer beyond 18 as your third argument in the vlookup? That would give an out of bounds for example. Cheers, Ben Hello Ben thanks For your help. I have a dynamic range : “Expenses!...

One way to create a dynamic Note: OFFSET is a volatile function, which means it recalculates with every change to a worksheet. With a modern machine and smaller data set, this should't cause a problem but you may see slower performance on large data sets. In that case, consider building a dynamic named range with the INDEX function instead. In the example shown, the formula used for the dynamic range is: =OFFSET(B5,0,0,COUNTA($B$5:$B$100),COUNTA($B$4:$Z$4)) This formula uses the OFFSET function to generate a range that expands and contracts by adjusting height and width based on a count of non-empty cells. The first argument in OFFSET represents the first cell in the data (the origin), which in this case is cell B5. The next two arguments are offsets for rows and columns, and are supplied as zero. The last two arguments represent height and width. Height and width are generated on the fly by using COUNTA, which makes the the resulting reference dynamic. For height, we use the COUNTA function to count non-empty values in the range B5:B100. This assumes no blank values in the data, and no values beyond B100. COUNTA returns 6. For width, we use the COUNTA function to count non-empty values in the range B5:Z5. This assumes no header cells, and no headers beyond Z5. COUNTA returns 6. At this point, the formula looks like this: =OFFSET(B5,0,0,6,6) With this information, OFFSET returns a reference to B5:G10, which corresponds to a range 6 rows height by 6 columns across. Note: Th...

In this tutorial, you will learn how to create a dynamic named range in Excel and how to use it in formulas to have new data included in calculations automatically. In last week's tutorial, we looked at different ways to define a static If you are working with a continuously changing data set, you may want to make your named range dynamic so that it automatically expands to accommodate newly added entries or contracts to exclude removed data. Further on in this tutorial, you will find detailed step-by-step guidance on how to do this. • • • How to create a dynamic named range in Excel For starters, let's build a dynamic named range consisting of a single column and a variable number of rows. To have it done, perform these steps: • On the Formula tab, in the Defined Names group, click Define Name. Or, press Ctrl + F3 to open the New… button. • Either way, the New Name dialogue box will open, where you specify the following details: • In the Name box, type the name for your dynamic range. • In the Scope dropdown, set the name's Workbook (default) is recommended in most cases. • In the Refers to box, enter either • Click OK. Done! In the following screenshot, we define a dynamic named range items that accommodates all cells with data in column A, except for the header row: OFFSET formula to define an Excel dynamic named range The generic formula to make a dynamic named range in Excel is as follows: OFFSET( first_cell, 0, 0, COUNTA( column), 1) Where: • first_cell - the first i...

An interesting phenomenon of language is that we often understand words that we cannot define. This is part of our natural linguistic faculty and usually doesn’t cause any problems, especially in ordinary conversation. In the world of engineering, though, we place greater emphasis on precision and clarity. Discussing technical details, mathematical relationships, and performance specifications is not always easy, and we can make the task more manageable and productive by striving to carefully employ and thoroughly understand the relevant terminology. One term that electrical engineers confront regularly, and in a variety of contexts, is “dynamic range.” Before you continue reading, take a minute and try to formulate a precise, comprehensive definition. In my opinion, it’s surprisingly difficult! In any case, I hope that by the end of this article we’ll all be ready with a solid explanation when someone stops us on the street and asks, “Hey, could you tell me what dynamic range is?” Static vs. Dynamic Range As far as I know, the term “static range” doesn’t exist. But let’s pretend that it does and use it to clarify the nature of dynamic range. “Range” is defined as the region of variation between two limits. “Static,” from a Greek verb related to standing or motionlessness, denotes a lack of movement, action, or change. Thus, static range suggests a region of possible variation in which the limits are not constrained by the need for input or output phenomena to actively and...
