Sighting proportions/angles of still life objects
Hello. I have been having trouble for a long time with trying to understand sighting. I've watched numerous videos and tried to apply them but I just can't grasp what they're talking about(yes I've even watched Proko's video). I know how you're supposed to hold your hand and keep your elbow locked and stuff my only form of confusion stems from applying what you observe and putting it on the page. many(of the videos I've watched) have said that you can fit the exact measurement you get on the page but it appears too small, so obviously you make it bigger, but that's what confuses me. If you make it bigger(let's say you just start off marking points to your page that represents the top and bottom of the object you are drawing) how can you determine that the points you measure are accurate?
Adding to the other posts, start with the larger shapes/objects and measure those, then work smaller. To do it with sight takes patience and practice, lots of practice. You won't be able to exactly measure from life unless you can physically measure the objects you are drawing which you then scale down (so a 40cm arm -> 4cm arm, then everything is scaled 10x smaller), so you just have to really keep an eye on how things look relative to each other. Have a look at this video by Brett Eviston, hope it helps: https://www.youtube.com/watch?v=PzlAgsPMU7k
Be aware man is no measuring device, so any measurement you take will have errors. There are two kinds of measuring. First there is sight sizing, where you work scale 1:1, putting things on paper the size you see them. Second, you have comparative measuring, where you compare sizes to one another as you see them, and on paper. Also, check out the proportional divider, which unites the two. Whatever you try, be prepared to make lots of mistakes aka to practice.
Well... I guess it's just to make sure the ratio is correct but not exact size. so if you enlarge something 2x then every length measurement should be 2x and every angle should stay the same.
