İlk olarak element belirleyip elementin fotoğrafını çekin ardından indirip picture box üzerinde view edebilirsiniz

  IWebElement element = driver.FindElement(By.Id("test"));
new Actions(driver).MoveToElement(element).Build().Perform();
Thread.Sleep(1000);
var sc = ((ITakesScreenshot)driver).GetScreenshot();
var remoteWebElement = element as RemoteWebElement;
using (var img = Image.FromStream(new MemoryStream(sc.AsByteArray)) as Bitmap)
{
if (remoteWebElement != null)
img?.Clone(new Rectangle(remoteWebElement.LocationOnScreenOnceScrolledIntoView, remoteWebElement.Size), img.PixelFormat).Save(apppath + @"captcha.jpeg", ImageFormat.Jpeg);
                        }
